超级web服务器yum 安装apache+源码编译tomcat+awstat+phpmadin+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httpdphp 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.comvim/etc/httpd/conf/httpd.conf
修改：ServerName www.example.com:80
DirectoryIndex index.html index.html.var index.php
NameVirtualHost192.168.56.10:80//开启虚拟主机为了以后做虚拟主机挂网站
<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/phpmyadminmv config.sample.inc.php config.sample.inc.php.bakcp 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';//指定你的mysql 数据库地址
$cfg['Servers'][$i]['controluser'] = 'root';$cfg['Servers'][$i]['controlpass'] = 'redhat'; //指定你的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'; //指定你的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/./configuremake cleanmakemake 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 / -namemcrypt.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
servicehttpd 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 root@192.168.56.10BY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.inivim /etc/php.inishort_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/bbschmod -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# chmod o-rx install.lock/
这两步不操作也可成功：
