启动php-fpm服务：

[root@phplichao ~]# netstat-anpt | grep php-fpm

[root@phplichao ~]#firewall-cmd –permanent –add-port=9000/tcp
success
[root@phplichao ~]#firewall-cmd –reload
Success
在该主机上新建虚拟主机目录用于存放网页文件
[root@phplichao ~]# mkdir -p/var/www/benet
至此php安装配置完毕，下面配置apache通过fastcgi协议调用php
6、配置apache(切换到apache主机上操作 )
在Apache2.4以后已经专门有一个模块针对FastCGI的实现，此模块为mod_proxy_fcgi.so，它其实是作为mod_proxy.so模块的扩充，因此，这两个模块都要加载
LoadModule proxy_modulemodules/mod_proxy.so
LoadModule proxy_fcgi_modulemodules/mod_proxy_fcgi.so
[root@www ~]# apachectl -M |grep proxy
proxy_module(shared)
proxy_fcgi_module (shared)
建立一个目录作为虚拟主机的家目录
[root@www ~]# mkdir -p /var/www/benet
编辑主配置文件httpd.conf，开启虚拟主机
启用Include conf/extra/httpd-vhosts.conf
同时定位 AddType；添加下面两行：让apache能识别php格式的页面
AddTypeapplication/x-httpd-php .php
AddTypeapplication/x-httpd-php-source .phps
并且定位至DirectoryIndex：支持php格式的主页
DirectoryIndex index.phpindex.html #添加index.php（最好添加在最前面）
配置虚拟主机支持使用fcgi
[root@www ~]# vi/usr/local/http-2.4.23/conf/extra/httpd-vhosts.conf
ServerAdmin [email protected]
DocumentRoot “/var/www/benet”
ServerName www.benet.com
ServerAlias benet.com
ErrorLog “logs/benet.com-error_log”
CustomLog”logs/benet.com-access_log” common
ProxyRequests Off
ProxyPassMatch ^/(.*\.php(/.*)?)$ fcgi://192.168.31.141:9000/var/www/benet/$1
#
# ProxyPassfcgi://192.168.31.141:9000/var/www/benet
#
Options FollowSymLinks
AllowOverride None
Require all granted
其中：
ProxyRequests off #关闭正向代理
ProxyPassMatch：把以.php结尾的文件请求发送到php-fpm进程，php-fpm至少需要知道运行的目录和URI，所以这里直接在fcgi://192.168.31.141:9000后指明了这两个参数，其它的参数的传递已经被mod_proxy_fcgi.so进行了封装，不需要手动指定。
特别注意的是，红色字体部分需要与
ProxyPassMatch
只有满足特定正则模式的内容才会匹配并执行此规则，这里的模式是，^/(.*\.php(/.*)?)$
从网站（虚拟主机
^ (caret) 和 $ (dollar)标志要匹配的路径的开始和结束
( )括号里的内容可以用 $1 来表示，以方便后面引用它。
fcgi:// 192.168.31.141:9000通过mod_proxy_fcgi 来转发的代理，使用 fastCGI 协议，转到PHP-FPM 监听的端口。
/path/to/your/documentroot/
非常重要！必须与虚拟主机的路径匹配，且必须是对应 php 文件在操作系统中的绝对路径。否则会找不到文件。
$1可以从原始请求扩展成整个请求路径的变量，这里指代前面( ) 里面匹配的那个路径（uri）
充：Apache httpd 2.4以前的版本中，要么把PHP作为Apache的模块运行，要么添加一个第三方模块支持PHP-FPM实现。
测试LAMP环境：
在mysql主机上创建用于php服务器连接的mysql账户
mysql> grant all on *.*to testuser@’%’ identified by ‘123456;
注意防火墙要允许mysql连接。
在php服务器上的/var/www/benet目录下创建.php的测试页：
[root@phplichao ~]# cat/var/www/benet/index.php
phpinfo();< /strong>
?>
[root@phplichao ~]# cat/var/www/benet/test1.php
$link=mysql_connect(‘192.168.31.225′,’testuser’,’123456′);
if ($link)echo”connection success……”;
mysql_close();
?>
测试访问
7、压力测试
网站性能压力测试是服务器网站性能调优过程中必不可缺少的一环。只有让服务器处在高压情况下，才能真正体现出软件、硬件等各种设置不当所暴露出的问题。
性能测试工具目前最常见的有以下几种：ab、http_load、webbench、siege。今天我们专门来介绍ab。
ab是apache自带的压力测试工具。 ab非常实用，它不仅可以对apache服务器进行网站访问压力测试，也可以对或其它类型的服务器进行压力测试。比如nginx、tomcat、IIS等。
下面我们开始介绍有关ab命令的使用：
1． ab的原理
2． ab的安装
3． ab参数说明
4． ab性能指标
5． ab实际使用
6．测试nginx性能
1）ab的原理
ab是apachebench命令的缩写。
ab的原理：ab命令会创建多个并发访问线程，模拟多个访问者同时对某一URL地址进行访问。它的测试目标是基于URL的，因此，它既可以用来测试apache的负载压力，也可以测试nginx、lighthttp、tomcat、IIS< /span>等其它Web服务器的压力。
ab命令对发出负载的计算机要求很低，它既不会占用很高CPU，也不会占用很多内存。但却会给目标服务器造成巨大的负载，其原理类似CC攻击。自己测试使用也需要注意，否则一次上太多的负载。可能造成目标服务器资源耗完，严重时甚至导致死机。
2）ab的安装
ab的安装非常简单，如果是源码安装apache的话，那就更简单了。 apache安装完毕后ab命令存放在apache安装目录的bin目录下。如下：
/usr/local/http2.4.23/bin/ab
如果apache 是通过yum的RPM包方式安装的话，ab命令默认存放在/usr/bin目录下。如下：
which ab
注意：如果不想安装apache但是又想使用ab命令的话，我们可以直接安装apache的工具包httpd-tools。如下：
yum -y install httpd-tools
查看ab是否安装成功，可以切换到上述目录下，使用ab �CV命令进行检测。如下：
[root@www ~]#/usr/local/http-2.4.23/bin/ab -V

3）ab参数说明
有关ab命令的使用，我们可以通过帮助命令进行查看。如下：
[root@cent05 ~]# ab–help
下面我们对这些参数，进行相关说明。如下：
-n：在测试会话中所执行的请求个数(即总请求数)。
-c：一次产生的请求个数（即并发用户数）。
[root@www ~]# ab-c 500 -n 10000 http://192.168.31.83/index.html

这部分数据用于描述每个请求处理时间的分布情况，比如以上测试，80%的请求处理时间都不超过66ms，这个处理时间是指前面的Time per request，即对于单个用户而言，平均每个请求的处理时间。
继续压力测试
我们再来进行一次压力测试，此时并发用户数为1000，其他条件不变，查看两次测试结果的吞吐量差别
4）ab性能指标< /p>
在进行性能测试过程中有几个指标比较重要：
1、吞吐率（Requests per second）
服务器并发处理能力的量化描述，单位是reqs/s，指的是在某个并发用户数下单位时间内处理的请求数。某个并发用户数下单位时间内能处理的最大请求数，称之为最大吞吐率。
记住：吞吐率是基于并发用户数的。这句话代表了两个含义：
a、吞吐率和并发用户数相关
b、不同的并发用户数下，吞吐率一般是不同的
计算公式：总请求数/处理完成这些请求数所花费的时间，即
Request persecond=Complete requests/Time taken for tests
必须要说明的是，这个数值表示当前机器的整体性能，值越大越好。
2、并发连接数（The number of concurrent connections）
并发连接数指的是某个时刻服务器所接受的请求数目，简单的讲，就是一个会话。
3、并发用户数（Concurrency Level）
要注意区分这个概念和并发连接数之间的区别，一个用户可能同时会产生多个会话，也即连接数。
4、用户平均请求等待时间（Time per request）
计算公式：处理完成所有请求数所花费的时间/（总请求数/并发用户数），即：
Time perrequest=Time taken for tests/（Completerequests/Concurrency Level）
5、服务器平均请求等待时间（Time per request:across all concurrentrequests）
计算公式：处理完成所有请求数所花费的时间/总请求数，即：
Time takenfor/testsComplete requests
可以看到，它是吞吐率的倒数。
同时，它也等于用户平均请求等待时间/并发用户数，即
Time perrequest/Concurrency Level
8、CentOS7.2下安装php加速软件
说明：
php安装目录：/usr/local/php5.6
php.ini配置文件路径：/etc/php.ini
1）安装xcache
wgethttp://xcache.lighttpd.net/pub/Releases/3.2.0/xcache-3.2.0.tar.gz #下载
[root@phpserver ~]# tar zxfxcache-3.2.0.tar.gz #解压
[root@phpserver ~]# cdxcache-3.2.0/ #进入安装目录
[[email protected]]# /usr/local/php5.6/bin/phpize#用phpize生成configure配置文件
[[email protected]]# ./configure –enable-xcache –enable-xcache-coverager–enable-xcache-optimizer –with-php-config=/usr/local/php5.6/bin/php-config #配置
[[email protected]]# make && make install #编译、安装
Installing sharedextensions: /usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/
安装完成之后，出现下面的界面，记住以下路径，后面会用到
/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/
2）创建xcache缓存文件
# touch /tmp/xcache
# chmod 777 /tmp/xcache
3）拷贝xcache后台管理程序到网站根目录
[[email protected]]# cp -r htdocs/ /var/www/benet/xcache
4）配置 php支持xcache
vi / etc/php.ini #编辑配置文件，在最后一行添加以下内容
[xcache-common]
extension =/usr/local/php5.6/lib/php/extensions/no-debug-zts-20131226/xcache.so

将xcache目录拷贝到 apache主机的网页文档目录下
[root@phpserver ~]# scp -r/var/www/benet/xcache/ [email protected]:/var/www/benet/
6）测试
service php-fpm restart #重启php-fpm
浏览器打开网站根目录下面的xcache
http://http://192.168.31.83/xcache可以看到如下页面：
至此，Linux下安装php加速软件Xcache教程完成

9、部署bbs论坛
Discuz的程序文件解压，并且将upload中所有文件放置到网站目录(php服务器的操作)
#unzipDiscuz_7.0.0_FULL_SC_UTF8.zip -d discus
# mv discuz/upload/ /var/www/benet/bbs
设置php-fpm的服务用户为下面文件的属主或者对其设置写权限，否则安装时会报错
#cd /var/www/benet/bbs
#chown -R nobodyconfig.inc.php attachments/ forumdata/ uc_client/data/cache/ templates/
#chmod -R 777uc_server/data/
修改php.ini文件
short_open_tag = On
# service php-fpm restart
web服务器也需要有静态文件(apache服务器上操作)
#unzipDiscuz_7.0.0_FULL_SC_UTF8.zip -d discus
# mv Discuz/upload/ /var/www/benet/bbs
设置httpd的服务用户对指定文件也需要有写权限
#cd /var/www/benet/bbs
#chown -R daemonconfig.inc.php attachments/ forumdata/ uc_client/data/cache/ templates/
在数据库服务器上创建bbs数据库及授权帐户
mysql> create databasebbsdb;
Query OK, 1 row affected(0.01 sec)
mysql> grant all onbbsdb.* to runbbs@’%’ identified by ‘pwd@123’;
Query OK, 0 rows affected, 1warning (0.03 sec)
置完成之后，输入httd：//192. 168.31.83/bbs/install即可安装
填写数据库的相关信息，添加数据库服务器的地址和MariaDB创建的数据库和用户密码，而后在设置bbs的管理员帐号密码就可以继续安装了。
剩下的根据提示安装即可。
出现上面这种情况是由于php服务器安装了discuz之后导致程序发生变化从而导致动态服务器和静态服务器的程序不一致，只需要手动把bbs服务器的文件和web服务器进行一次同步即可，如果想实现自动同步，需要使用其他服务，如initory+rsync、sersync等工具。
#scp -r /var/www/benet/bbs/*[email protected]:/var/www/benet/bbs/
动态服务器和静态服务器同步文件之后，再次访问bbs的网址就正常了。
至此本环境论坛全部打好，只需要在简单的维护即可！买一个云主机IP输入自己的公网IP，就可以让广大网民访问了。
