Mac OS X 安装mysql过程

从mysql官网http://mysql.com/downloads/mysql/下载dmg格式的安装文件。推荐使用64位（x86, 64-bit）。

打开安装包，第一个扩展名为pkg的文件即是安装文件。mysql不必编译安装，直接运行pkg安装即可。MySQL的Mac OS X PKG安装到/usr/local/mysql-VERSION，并且还会生成一个符号连接，/usr/local/mysql，指向新的位置。如果有/usr/local/mysql目录，首先将它改名为/usr/local/mysql.bak。安装完后，安装器会自动执行mysql_install_db在MySQL数据库中创建授权表。

安装完成后，双击MySQL.prefPane文件，即可给系统编好设置添加一个mysql的管理面板，可以在系统偏好设置中开启和关闭mysql。

如果安装了MySQL.prefPane这个偏好设置项，打开系统偏好设置会看到新增一项“MySQL”项。打开后可以启动和停止mysql服务。同时可以看到下方有个单选框“Automatically Start MySQL Server on Startup”，就是是否随系统开机启动Mysql服务，选中它的话，下面这项MySQLStartupItem.pkg就不必安装了。

MySQLStartupItem.pkg这个文件是干吗的呢？它提供了mysql随mac系统开机启动的功能。如何取消随系统启动呢？前面刚刚说完，不选中随机启动就行了。

仔细阅读readme.txt文件会发现，你可以为mysql和mysqladmin做两个alias。这样就不必每次输入完整路径来执行mysql和mysqladmin了。

在终端中运行：

alias mysql=/usr/local/mysql/bin/mysql
alias mysqladmin=/usr/local/mysql/bin/mysqladmin

1 2	alias mysql=/usr/local/mysql/bin/mysql alias mysqladmin=/usr/local/mysql/bin/mysqladmin

刚安装完的mysql是没有密码的。可以使用如下命令来给root用户创建一个密码，例如我们给mysql 的root用户设置初始密码为123456

/usr/local/mysql/bin/mysqladmin -u root password 123456

1	/usr/local/mysql/bin/mysqladmin -u root password 123456

除了在控制面板中开启和关闭mysql，还可以使用终端命令行来控制启动，停止和重启：

sudo /Library/StartupItems/MySQLCOM/MySQLCOM [start|stop|restart]

1	sudo /Library/StartupItems/MySQLCOM/MySQLCOM [start\|stop\|restart]

OK，安装到此完成。

部署War包到Tomcat根目录位置(Ubuntu/CentOS)

操作系统：CentOS 5.6

对于ubuntu 14.04来说，Tomcat的war包默认目录路径位置在 /var/lib/tomcat7/webapps

对于ubuntu 18.04来说，Tomcat的war包默认目录路径位置在 /var/lib/tomcat8/webapps 或 /var/lib/tomcat9/webapps

对于CentOS 7来说，Tomcat的war包默认目录路径位置在 /usr/share/tomcat/webapps

Tomcat版本：apache-tomcat-6.0.33

在Tomcat中部署war包很简单：

首先，直接把相应的war包放到$TOMCAT_HOME/webapps下，不用建目录；

然后，修改$TOMCAT_HOME/conf/server.xml，在Host配置段中添加类似于如下内容：

<Context path="/" docBase="hdfs-webdav.war" debug="0" privileged="true" reloadable="true"/>

1	<Context path="/" docBase="hdfs-webdav.war" debug="0" privileged="true" reloadable="true"/>

其中，docBase参数标识的是war包的名称。

访问时，使用如下地址进行访问：http://ip:port/hdfs-webdav

如果要把war包部署到Tomcat根目录，直接使用http://ip:port进行访问，需要的操作稍微复杂一些：

一、把war包解压，部署到除$TOMCAT_HOME/webapps以外的目录

二、删除$TOMCAT_HOME/ webapps/ROOT目录下的所有文件

三、在$TOMCAT_HOME/conf/Catalina/localhost目录下，新建一个ROOT.xml文件，写入类似于如下内容：

<?xml version='1.0' encoding='utf-8'?>
<Context path="/" docBase="/usr/local/tomcat-6.0/webdav" debug="0" privileged="true" reloadable="true"/>

1 2	<?xml version='1.0' encoding='utf-8'?> <Context path="/" docBase="/usr/local/tomcat-6.0/webdav" debug="0" privileged="true" reloadable="true"/>

其中，docBase指向的是war包解压后的目录名称，需绝对路径。

一个简单的Jsp+Servlet实例

开发环境Eclipse+Tomcat7

1、先创建web project，项目名为Hello，

2、在WebRoot 目录下创建login.jsp文件，只需修改body中的内容，如下所示：

<body>
   <form action="login">
   username:<input type="text" name="username"><br>
   password:<input type="password" name="pwd"><br>
   <input type="submit">
   </form>
 </body>

<body>

username:<input type="text" name="username"><br>

password:<input type="password" name="pwd"><br>

</form>

</body>

3、在scr目录下的com.ht.servlet编写AcountBean.java文件，代码如下：

package com.ht.servlet;

public class AccountBean {
private String username = "";
private String password = "";
public String getPassword() {
 return password;
}
public void setPassword(String password) {
 this.password = password;
}
public String getUsername() {
 return username;
}
public void setUsername(String username) {
 this.username = username;
}
}

package com.ht.servlet;

public class AccountBean {

private String username = "";

private String password = "";

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

4、在scr目录下的com.ht.servlet编写servlet类CheckAccount.java文件，代码如下：

package com.ht.servlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;

public class CheckAccount extends HttpServlet {

 @Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {
 doGet(req,resp);
 }

 @Override
public void doGet(HttpServletRequest req, HttpServletResponse resp)
  throws ServletException, IOException {
 HttpSession session = req.getSession();
  AccountBean account = new AccountBean();
  String username = req.getParameter("username");
 String pwd = req.getParameter("pwd");
  account.setPassword(pwd);
 account.setUsername(username);
  if((username != null)&&(username.trim().equals("jsp"))) {
  if((pwd != null)&&(pwd.trim().equals("1"))) {
   System.out.println("success");
   session.setAttribute("account", account);
    String login_suc = "success.jsp";
   resp.sendRedirect(login_suc);
    return;
  }
 }
 String login_fail = "fail.jsp";
 resp.sendRedirect(login_fail);
  return;
}

}

package com.ht.servlet;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import javax.servlet.http.HttpSession;

public class CheckAccount extends HttpServlet {

@Override

protected void doPost(HttpServletRequest req, HttpServletResponse resp)

throws ServletException, IOException {

doGet(req,resp);

}

@Override

public void doGet(HttpServletRequest req, HttpServletResponse resp)

throws ServletException, IOException {

HttpSession session = req.getSession();

AccountBean account = new AccountBean();

String username = req.getParameter("username");

String pwd = req.getParameter("pwd");

account.setPassword(pwd);

account.setUsername(username);

if((username != null)&&(username.trim().equals("jsp"))) {

if((pwd != null)&&(pwd.trim().equals("1"))) {

System.out.println("success");

session.setAttribute("account", account);

String login_suc = "success.jsp";

resp.sendRedirect(login_suc);

return;

}

String login_fail = "fail.jsp";

resp.sendRedirect(login_fail);

return;

}

5、在WebRoot目录下编写success.jsp文件成功后跳转

<body>
   <%
   AccountBean account = (AccountBean)session.getAttribute("account");
    %>
   username:<%= account.getUsername()%>
    <br>
    password:<%= account.getPassword() %>
 </body>

<body>

AccountBean account = (AccountBean)session.getAttribute("account");

username:<%= account.getUsername()%>

<br>

password:<%= account.getPassword() %>

</body>

6、在WebRoot目录下编写fail.jsp文件失败后跳转

<body>
  Login Failed! <br>
 </body>

<body>

</body>

7、修改web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>

Eclipse with Tomcat 7 on Ubuntu

Eclipse with Tomcat V7.0 in Ubuntu
1. Download Eclipse from the Eclipse web site. (J2EE version)
2. Download Tomcat version 7 or install it via apt-get
apt-get install tomcat7 tomcat7-admin tomcat7-common tomcat7-docs tomcat7-examples
3. Set the following configuration:

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo ln -s /var/log/tomcat7 logs
sudo chmod -R 777 /usr/share/tomcat7/conf

cd /usr/share/tomcat7

sudo ln -s /var/lib/tomcat7/conf conf

sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy

sudo ln -s /var/log/tomcat7 logs

sudo chmod -R 777 /usr/share/tomcat7/conf

3. Run eclipse
4. Add a view ( Windows -> Show View -> Other -> Server -> Servers -> OK )
5. Go to the view
6. Add a Tomcat v7 (consider /user/share/tomcat7 as your path)
7. Enjoy Tomcat 7 in Eclipse.

Eclipse add Tomcat 7 blank server name

I was trying to add Tomcat 7 in my Eclipse in Ubuntu. When I click "Add new server" in Eclipse and select "Tomcat v7.0 Server", the field "Server Name" is blank and I cannot type in anything in that textbox as shown below:

It is a bug in Eclipse. I had exactly the same problem, also on Ubuntu with Eclipse Java EE Juno.

Here is the workaround that worked for me:

1.Close Eclipse
2.In {workspace-directory}/.metadata/.plugins/org.eclipse.core.runtime/.settings delete the following two files:
org.eclipse.wst.server.core.prefs
org.eclipse.jst.server.tomcat.core.prefs
3.Restart Eclipse

Tomcat在Mac平台安裝

到http://tomcat.apache.org下載tomcat版,例如apache-tomcat-7.0.42.tar.gz
将apache-tomcat-7.0.42.tar.gz 解压缩到目标目录
执行

 chmod a+x apache-tomcat-7.0.42/bin/*.sh

1	chmod a+x apache-tomcat-7.0.42/bin/*.sh

设置管理用户密码:
编辑 apache-tomcat-7.0.42/conf/tomcat-users.xml , 加入

<role rolename="manager-gui"/>
<user username="User" password="password" roles="manager-gui"/>

1 2	<role rolename="manager-gui"/> <user username="User" password="password" roles="manager-gui"/>

設定好後執行 apache-tomcat-7.0.42/bin/startup.sh , 再使用browser連到http://localhost:8080, 如果可以看到以下画面, Tomcat Server的安裝算是初步完成

設定Launchd主要讓Mac OS X server啟動時, 也順便啟動Tomcat Server, Launchd有點類似Windows的NT Service使用Launchd來啟動Tomcat Server

1.到 apache-tomcat-7.0.42/bin/目錄下新增一個檔案 launchd_wrapper.sh, 內容如下

#!/bin/bash
function shutdown()
{
date
echo "Shutting down Tomcat"
$CATALINA_HOME/bin/catalina.sh stop
}
date
echo "Starting Tomcat Server"
export CATALINA_PID=/tmp/$$
# Uncomment to increase Tomcat's maximum heap allocation
# export JAVA_OPTS=-Xmx512M $JAVA_OPTS
export JAVA_OPTS="-Xms256m -Xmx512m -XX:MaxPermSize=256m"
export CATALINA_OPTS="-DHUDSON_HOME=/Users/admin/hudson"
. $CATALINA_HOME/bin/catalina.sh start
# Allow any signal which would kill a process to stop Tomcat
trap shutdown HUP INT QUIT ABRT KILL ALRM TERM TSTP

#!/bin/bash

function shutdown()

{

date

echo "Shutting down Tomcat"

$CATALINA_HOME/bin/catalina.sh stop

}

date

echo "Starting Tomcat Server"

export CATALINA_PID=/tmp/$$

# Uncomment to increase Tomcat's maximum heap allocation

# export JAVA_OPTS=-Xmx512M $JAVA_OPTS

export JAVA_OPTS="-Xms256m -Xmx512m -XX:MaxPermSize=256m"

export CATALINA_OPTS="-DHUDSON_HOME=/Users/admin/hudson"

. $CATALINA_HOME/bin/catalina.sh start

# Allow any signal which would kill a process to stop Tomcat

trap shutdown HUP INT QUIT ABRT KILL ALRM TERM TSTP

请注意 ,launchd_wrapper.sh要使用

chmod a+x launchd_wrapper.sh

1	chmod a+x launchd_wrapper.sh

使其具有执行权限

2. 加入tomcat for Launchd 文件, 到/Library/LaunchDaemons目录使用

 sudo touch tomcat.plist

1	sudo touch tomcat.plist

新增tomcat.plist

3. 使用

sudo vi tomcat.plist

1	sudo vi tomcat.plist

, 编辑tomcat.plist, 文件內容如下, 要注意的是/Users/admin为安装目录, 请改成你的目录

<key>UserName</key>

</dict>

</plist>

4.手动测试Launchd

sudo launchctl load -w /Library/LauhchDaemons/tomcat.plist

1	sudo launchctl load -w /Library/LauhchDaemons/tomcat.plist

停止指令

sudo launchctl unload -w /Library/LaunchDaemons/tomcat.plist

1	sudo launchctl unload -w /Library/LaunchDaemons/tomcat.plist

测试OK后, 下次重新开机Tomcat Server就会自己执行了.

ubuntu下安装Apache+PHP+Mysql

步骤一，安装apache2

sudo apt-get install apache2

1	sudo apt-get install apache2

安装完成。
运行如下命令重启下：

sudo /etc/init.d/apache2 restart

1	sudo /etc/init.d/apache2 restart

在浏览器里输入http://localhost或者是http://127.0.0.1，如果看到了It works!，那就说明Apache就成功的安装了，Apache的默认安装，会在/var下建立一个名为www的目录，这个就是Web目录了，所有要能过浏览器访问的Web文件都要放到这个目录里。

步骤二，安装php:

sudo apt-get install libapache2-mod-php5 php5

1	sudo apt-get install libapache2-mod-php5 php5

此外，建议安装扩展php5-gd php5-mysql，安装方式同上.

安装完后，我们要重新启动Apache，让它加载PHP模块：

sudo /etc/init.d/apache2 restart

1	sudo /etc/init.d/apache2 restart

接下来，我们就在Web目录下面新建一个test.php文件来测试PHP是否能正常的运行，命令：

sudo gedit /var/www/test.php

1	sudo gedit /var/www/test.php

然后输入:

<?php echo  hello,world! ?>

1	<?php echo hello,world! ?>

接着保存文件,在浏览器里输入http://127.0.0.1/test.php，如果在网页中显示hello,world!!，那就说明PHP已经正常运行了。

步骤三,安装mysql数据库:

sudo apt-get install mysql-server mysql-client

1	sudo apt-get install mysql-server mysql-client

apt-get程序会自动下载安装最新的mysql版本。在安装的最后，它会要求里输入root的密码，注意，这里的root密码可不是Ubuntu的root密码啊，是你要给MySQL设定的root密码。

步骤四,安装phpmyadmin-Mysql数据库管理

sudo apt-get install phpmyadmin

1	sudo apt-get install phpmyadmin

phpmyadmin设置：

在安装过程中会要求选择Web server：apache2或lighttpd，使用空格键选定apache2，按tab键然后确定。然后会要求输入设置的Mysql数据库密码连接密码Password of the database’s administrative user。

然后将phpmyadmin与apache2建立连接，以我的为例：www目录在/var/www，phpmyadmin在/usr/share /phpmyadmin目录，所以就用命令：

sudo ln -s /usr/share/phpmyadmin /var/www

1	sudo ln -s /usr/share/phpmyadmin /var/www

建立链接。

phpmyadmin测试：在浏览器地址栏中打开http://localhost/phpmyadmin。

以上ALMP的基本组件就安装完毕了，下面我们再来看一些其他的设置：

步骤五，设置Ubuntu文件执行读写权限

LAMP组建安装好之后，PHP网络服务器根目录默认设置是在：/var/www。由于Linux系统的安全性原则，改目录下的文件读写权限是只允许root用户操作的，所以我们不能在www文件夹中新建php文件，也不能修改和删除，必须要先修改/var/www目录的读写权限。在界面管理器中通过右键属性不能修改文件权限，得执行root终端命令：

sudo chmod 777 /var/www

1	sudo chmod 777 /var/www

然后就可以写入html或php文件了。777是linux中的最高权限，表示可读，可写，可执行。

处理在64位Ubuntu使用jd-gui报错error while loading shared libraries: libgtk-x11-2.0.so.0

在64位Ubuntu中使用jd-gui反编译时出现错误：
error while loading shared libraries: libgtk-x11-2.0.so.0

此时，需要安装如下依赖包，即可：

(Ubuntu 13.04 x64)

$ sudo apt-get install ia32-libs-gtk libglib2.0-dev

1	$ sudo apt-get install ia32-libs-gtk libglib2.0-dev

(Ubuntu 13.10 x64)

$ sudo apt-get install libgtk2.0-0:i386 libxxf86vm1:i386 libsm6:i386 libglib2.0-dev libcanberra-gtk-module:i386 gtk2-engines-murrine:i386

1	$ sudo apt-get install libgtk2.0-0:i386 libxxf86vm1:i386 libsm6:i386 libglib2.0-dev libcanberra-gtk-module:i386 gtk2-engines-murrine:i386

Ubuntu下远程桌面rdesktop的安装及配置

Rdesktop是Linux操作系统下的一款远程桌面工具，可以用来链接Windows系统
使用rdesktop来指定分辨率，让远程桌面刚好填充到空白区域：
在终端里敲：

rdesktop 远程ip -u 用户名 -p 密码 -a 16 -g 1024x768 -r sound:local -5

1	rdesktop 远程ip -u 用户名 -p 密码 -a 16 -g 1024x768 -r sound:local -5

其中-g 参数就是指定分辨率。因为我是1280*800 所以我使用1024*768的分辨率是正好的。你可以根据你的情况来调整分辨率，找到一个最佳值。

其中-a参数指定的是16色。
但这有个缺点，就是每次都要敲一堆参数，太麻烦。所以，我们可以使用别名来简化这个命令。
打开~/.bashrc 这个文件。在里面可以添加别名（写在最后面就可以了）：
例如：

rdesktop alias rdp='rdesktop -a 16 -g 1024x768 -r sound:local -5 '

1	rdesktop alias rdp='rdesktop -a 16 -g 1024x768 -r sound:local -5 '

注意1024x768之间的x别写成*或其他，否则分辨率设置不起作用。
关闭终端。重新打开终端，此时只要敲 rdp ip地址 -u 用户名 -p 密码就可以了。
而且你还可以把你常用的远程连接写成别名：

alias rdp='rdesktop 192.168.111.231 -u Administrator -p 1 -a 16 -g 1024x728 -r sound:local -5 '

1	alias rdp='rdesktop 192.168.111.231 -u Administrator -p 1 -a 16 -g 1024x728 -r sound:local -5 '

这样只要敲rdp就可以打开了。
PS：1、用户主目录下的.bashrc 文件会在终端启动的时候被终端读取。
2、此外，-g 还可以以百分比的形式填写如下：

rdesktop -g 80% -u dell 192.168.111.231

1	rdesktop -g 80% -u dell 192.168.111.231

Example compiling the latest Audacity source code on Ubuntu

These simple steps have been tested building Audacity 2.x on Ubuntu 11.04 (natty) and onwards including 13.04 (raring). The steps should also work with appropriate modification on most other Debian-based systems and for most legacy 1.3 versions of Audacity.

Open a terminal and type the following commands:

sudo apt-get install subversion
svn checkout http://audacity.googlecode.com/svn/audacity-src/trunk/ audacity-read-only
sudo apt-get build-dep audacity
sudo apt-get install cmake (currently required for building Audacity 2.0.3-alpha from HEAD)
cd audacity-read-only
./configure
sudo make install

sudo apt-get install subversion

svn checkout http://audacity.googlecode.com/svn/audacity-src/trunk/ audacity-read-only

sudo apt-get build-dep audacity

sudo apt-get install cmake (currently required for building Audacity 2.0.3-alpha from HEAD)

cd audacity-read-only

./configure

sudo make install

This should now give you the Audacity program at usr/local/bin and the plug-ins at usr/local/share/audacity.
On occasions, changes to latest Audacity HEAD may require you to regenerate the configure file before running it. To do this

sudo apt-get install autogen
chmod +x ./autogen.sh
./autogen.sh

sudo apt-get install autogen

chmod +x ./autogen.sh

./autogen.sh
