Centos7搭建apache+php5.4环境

1.安装

　　yum -y install httpd

2.开启apache服务

　　systemctl start httpd.service

3.设置apache服务开机启动

　　systemctl enable httpd.service

4.apache重启

　　systemctl restart httpd

5.卸载

　　yum erase httpd.x86_64

配置修改 /etc/httpd/conf/httpd.conf

• AllowOverride None 讲None改为 All 在APACHE里面去配置 (注意其他地方的AllowOverride也统统设置为ALL)

  <Directory>
  AllowOverride ALL
  Options None
  Order allow,deny
  Allow from all
  </Directory>

• 绑定 ServerName localhost:80

apache性能优化

配置修改 /etc/httpd/conf/httpd.conf

TraceEnable off
ServerTokens  Prod
ServerSignature  off

配置修改 /etc/httpd/conf.modules.d/00-mpm.conf

<IfModule mpm_prefork_module>
    StartServers 10
    MinSpareServers 10
    MaxSpareServers 20
    ServerLimit 2000
    MaxRequestWorkers 1500
    MaxConnectionsPerChild 10000
</IfModule>

配置修改 /etc/sysctl.conf

net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_max_tw_buckets = 5000

修改后配置文件使之生效的办法：sysctl -p

php5.4安装

升级以下centos的软件仓库

#rpm -Uvh https://mirror.webtatic.com/yum/el7/epel-release.rpm

#rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

#yum -y install php

#yum -y install php-gd php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring

#yum -y install epel-release //扩展包更新包

#yum -y update //更新yum源

#yum -y install gcc

#yum -y install tcl

#yum -y install php-mcrypt

安装php支持php-redis

　　yum -y install php-redis

安装低版本php-redis

　　yum -y install php-pecl-redis-2.2.8-1.el7.x86_64

ThinkPHP 去掉 public 和 index.php

保存到.htaccess文件下

<IfModule mod_rewrite.c>
 RewriteEngine on
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteRule ^(.*)$ index.php/$1 [QSA,PT,L]
</IfModule>

windows 统计连接80端口数

netstat -ano | find ":80" /c

linux 统计连接80端口数

netstat -nat|grep -i "80"|wc -l
