超级web服务器yum 安装apache+源码编译tomcat+awstat+phpmyadmin+mysql+php+AB压力测试

实验环境：

两台机器：Centos6.4

机器一： 192.168.56.10  安装httpd  php   等整合

机器二： 192.168.56.11 安装 mysql

========================================================================================

（iptables -t nat -I PREROUTING -d 外IP -p tcp -m tcp --dport 端口 -j DNAT --to-destination 外网IP：端口）

========================================================================================

机器一：

1. yum -y install *libxml2* httpd* PHP* *gcc* mysql mysql-devel ( 这里的mysql 是客户端）

vim  /etc/hosts      

    192.168.56.10    www.example.com

    192.168.56.10    web.example.com

vim  /etc/httpd/conf/httpd.conf

修改：ServerName www.example.com:80

      DirectoryIndex index.html index.html.var index.php

         

      NameVirtualHost  192.168.56.10:80  //开启虚拟主机

      

<VirtualHost 192.168.56.10:80>

    ServerAdmin www.example.com                             

    DocumentRoot /var/www/html

    ServerName www.example.com

    ErrorLog logs/www.example.com-error_log

    CustomLog logs/www.example.com-access_log common

</VirtualHost>

2. 解压phpMyadmin-*

cp -RV   phpmyadmin-*                /var/www/html/phpmyadmin

cd     /var/www/html/phpmyadmin

mv config.sample.inc.php    config.sample.inc.php.bak

cp config.sample.inc.php.bak     config.inc.php

vim config.inc.php

$cfg['blowfish_secret'] = 'redhat';  //随便指定，不为空

$cfg['Servers'][$i]['auth_type'] = 'cookie';

$cfg['Servers'][$i]['host'] = '192.168.56.11';//指定mysql 数据库地址

$cfg['Servers'][$i]['controluser'] = 'root';

$cfg['Servers'][$i]['controlpass'] = 'redhat'; //指定mysql 数据库的用户名和密码

$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';

$cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';

$cfg['Servers'][$i]['relation'] = 'pma_relation';

$cfg['Servers'][$i]['table_info'] = 'pma_table_info';

$cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';

$cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';

$cfg['Servers'][$i]['column_info'] = 'pma_column_info';

$cfg['Servers'][$i]['history'] = 'pma_history';

$cfg['Servers'][$i]['tracking'] = 'pma_tracking';

$cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';

vim libraries/config.default.php 

$cfg['blowfish_secret'] = 'redhat';

$cfg['Servers'][$i]['host'] = '192.168.56.11';

$cfg['Servers'][$i]['port'] = '3306'; //指定Mysql 数据库端口

$cfg['Servers'][$i]['controluser'] = 'root';

$cfg['Servers'][$i]['controlpass'] = 'redhat';

$cfg['Servers'][$i]['user'] = 'root';

$cfg['Servers'][$i]['password'] = 'redhat';

//这个里面默认的为空，找到他们写入跟上面一样的数值：

$cfg['Servers'][$i]['pmadb'] = 'phpmyadmin';

$cfg['Servers'][$i]['bookmarktable'] = 'pma_bookmark';

$cfg['Servers'][$i]['relation'] = 'pma_relation';

$cfg['Servers'][$i]['table_info'] = 'pma_table_info';

$cfg['Servers'][$i]['table_coords'] = 'pma_table_coords';

$cfg['Servers'][$i]['pdf_pages'] = 'pma_pdf_pages';

$cfg['Servers'][$i]['column_info'] = 'pma_column_info';

$cfg['Servers'][$i]['history'] = 'pma_history';

$cfg['Servers'][$i]['tracking'] = 'pma_tracking';

$cfg['Servers'][$i]['designer_coords'] = 'pma_designer_coords';

===============================================================

客户端输入192.168.56.10/phpmyadmin   会报 mcrypt 插件错误：yum 安装PHP 没有mcrypt的插件。源码安装PHP你又必须指定 Mysql的安装位置。由于数据库和PHP分两台机器没法指定mysql的安装位置。所以我们采用编译安装模块。

========================================================================

1。开始编译 安装：libmcrypt-2.5.8

./configure    make && make install

2。开始编译 安装：mhash-0.9.9.9 

   /configure    make && make install

3。开始编译 安装：mcrypt-2.6.8 

 /configure    make && make install

===================================================================

以上三个包编译安装为了一个目的就是解决 php 没有 mcrypt.so 模块的问题

====================================================================

4。开始编译 源码PHP ：（只编译不安装）php-5.2.13

./configure  --with-mcrypt

5. 编译完成以后，进入解压以后源码包的存放mcrypt的目录下

 cd php-5.2.13/ext/mcrypt/

===========================================================

phpize 敲这条命令 

aclocal 再敲这条命令 

如果没有phpize 这条命令你需要安装php-devel.

亲身试验RHEL 光盘包没这个包。而centos里面有这个包。

敲这条命令的目的是为了在 mcrypt生产 configure 文件 。默认没有configure的

=====================================================================

6. 然后安装执行：

cd php-5.2.13/ext/mcrypt/

./configure

make clean

make

make install

7. 现在php的安装目录下面应该有了mcrypt.so 的文件了。

实在不清楚在哪里就用命令找一下

find / -name  mcrypt.so

我找到的在这个路径下 ：

/usr/lib64/php/modules/mcrypt.so

/tmp/php-5.2.13/ext/mcrypt/modules/mcrypt.so

/tmp/php-5.2.13/ext/mcrypt/.libs/mcrypt.so

==========================================================================

8。 最后一步，把mcrypt.so 让php 调用识别就行了 ：

vim  /etc/php.ini

extension=mcrypt.so

service  httpd restart

========================================================================

有些报错可能会遇到，我没遇到;这里就标识出来吧：

特别注意:

1、phpize需在解压后的源码包下执行，执行后生成configure脚本

2、运行./configure时,如果提示

configure: error: Cannot find php-config. Please use --with-php-config=PATH

请使用:

./configure --with-php-config=/php-install-path/bin/php-config #而不是使用php.ini

==============================================================================

机器二： 192.168.56.11  比较简单

yum  -y install mysql*

service mysqld restart

mysqladmin -u root password redhat

mysql -u root -p

输入密码进入mysql：

use mysql;

select host, user，password from user; 

//查看到的只有本地的连接

| host                  | user | password                                  |

+-----------------------+------+-------------------------------------------+

| localhost             | root | *84BB5DF4823DA319BBF86C99624479A198E6EEE9 |

| SERVER-11.example.com | root |                                           |

| 127.0.0.1             | root |                                           |

| localhost             |      |                                           |

| SERVER-11.example.com |      |   

//所以，我们要添加远程能够连接：

GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'redhat';

root@%  root 是你mysql的用户名 % 代表所有主机： 这里可以写IP：如 [email protected]

BY  指定的是你root的密码 ：（这里的密码和上面PHPMyadmin 里面保持一致）

flush privileges; //使修改即时生效

=================================================================================

再用select host, user，password from user; 查看

+-----------------------+------+-------------------------------------------+

| host                  | user | password                                  |

+-----------------------+------+-------------------------------------------+

| localhost             | root | *84BB5DF4823DA319BBF86C99624479A198E6EEE9 |

| SERVER-11.example.com | root |                                           |

| 127.0.0.1             | root |                                           |

| localhost             |      |                                           |

| SERVER-11.example.com |      |                                           |

| %                     | root | *84BB5DF4823DA319BBF86C99624479A198E6EEE9 |

+-----------------------+------+-------------------------------------------+

=====================解决完成mcrypt.so完===================================

==========================================================================

安装 Discuz动网论坛

1. 修改php.ini

vim /etc/php.ini

short_open_tag = on

2. 解压论坛：unzip Discuz_7.2_FULL_SC_UTF8.zip -d discus

mv discus/upload/*  /var/www/htlm/bbs

service httpd restart

浏览器打开：http://192.168.56.10/bbs/install/index.php

点击安装下一步，会出现 什么不可读写，需要下一步把红色部分变成读写：

解决方法：(权限必须777；755试了还是不能写）

cd /var/www/html/bbs

chmod -R 777 config.inc.php attachments/

chmod -R 777 forumdata/ uc_client/data/cache/

service httpd restart

=========================================================================

在数据库服务器上创建bbs的数据库：192.168.56.11

create database discuz;

=========================================================================

在浏览器输入http://192.168.56.10/bbs/install/index.php 下一步，下一步。

指定数据库服务器：92.168.56.11

数据库名字：discuz

数据库用户名：root

数据库密码：redhat

数据库表前缀：cdb_discuz

下面写管理员密码：

安装完成： http://192.168.56.10/bbs

网站前台：http://www.example.com/bbs/index.php

访问bbs后台：http://www.example.com/bbs/admincp.php

=============================================================

有些情况出不来页面就把instll.php 删除

root@localhost bbs]# mv install/ install.lock

[root@localhost bbs]# chmod o-rx install.lock/

这两步不操作也可成功：

==============================================================

额外操作：可以不做，没实质意义：

AB 压力测试 ：

[root@localhost ~]# ulimit -a | grep "open files"

使用awstats 分析web 日志：

mv awstats-6.95/ /usr/local/awstats

cd /usr/local/awstats/tools/

./awstats_configure.pl

 指定你的ｈｔｔｐ安装的路径，我是yum安装的，所以指定：
