CentOS 6.6搭建LNMP环境

一、安装前

1、关闭linux的安全机制

vim /etc/selinux/config

SELINUX=enforcing  改为  SELINUX=disabled

2、关闭iptables防火墙

vim /etc/sysconfig/iptables   #把里边的条例全部dd删除掉，wq保存退出

service iptables stop            #关闭iptables
   chkconfig iptables off          #开机不自启动iptables

3、配置yum源（本地，网络都可以）#如果能上网的话建议配置网络yum源

详细如何配置yum请阅读  http://blog.csdn.net/allen_a/article/details/51198585

4、重启系统

reboot

二、安装篇

yum list
yum clean all
yum -y install pcre-devel zlib-devel
yum -y install gcc* gcc-*
yum remove httpd
rpm -qa httpd
1）编译安装nginx
A.安装支持软件
yum -y install pcre-devel zlib-devel
B.创建运行用户、组
useradd -M -s /sbin/nologin nginx
C.编译安装Nginx
tar zxvf nginx-1.6.0
cd nginx-1.6.0
./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module
make && make install

/usr/local/nginx/sbin/nginx   # 启动Nginx

访问Nginx服务器的IP,会出现    欢迎来到Nginx

nginx开启，关闭命令

killall -s HUP nginx
killall -1 nginx

killall -s QUIT nginx
killall -3 nginx

查看日志信息
cd /usr/local/nginx/logs/

natstat -anpt | grep nginx

优化应用程序控制
vim /etc/init.d/nginx
#!/bin/bash
# chkconfig: - 99 20
# description: Nginx Server Control Script
PROC="/usr/local/nginx/sbin/nginx"
PID="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
  $PROC
  $PROG
  ;;
stop)
  kill -s QUIT $(cat $PID)
  ;;
restart)
  $0 stop
  $0 start
  ;;
reload)
  kill -s HUP $(cat $PID)
  ;;
status)
  [ -f $PID ] &> /dev/null
       if [ $? -eq 0 ]
          then 
          netstat  -anpt | grep nginx
       else
          echo "Nginx is not running."
        fi   
  ;;
*)
  echo "Usage: $0 {start|stop|restart|reload|status}"
esac
exit 0

检查语法
nginx -t

检测安装环境，卸载rpm的应用程序
yum remove httpd mysql php

1、安装MySQL数据库
1）编译安装MySQL数据库
yum -y install ncurses-devel

tar zxvf cmake-2.8.6.tar.gz
cd cmake-2.8.6
./configure 
gmake 
gmake install

tar zxvf mysql-5.5.22.tar.gz
cd mysql-5.5.22
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_EXTRA_CHARSETS=ALL -DSYSCONFIGDIR=/etc
make && make install

2）优化调整
rm -rf /etc/my.cnf
cp support-files/my-medium.cnf /etc/my.cnf
cp support-files/mysql.server /etc/rc.d/init.d/mysqld
chmod +x /etc/rc.d/init.d/mysqld 
chkconfig --level 35 mysqld on
echo "PATH=$PATH:/usr/local/mysql/bin" >> /etc/profile
. /etc/profile 或者 source /etc/profile

3）初始化数据库
groupadd mysql
useradd -M -s /sbin/nologin mysql -g mysql
chown -R mysql:mysql /usr/local/mysql/

/usr/local/mysql/scripts/mysql_install_db  --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/ --user=mysql

4）启动数据库
service mysqld start
mysqladmin -u root password 'pwd123'
mysql -u root -p

2、安装PHP解析环境
1）编译安装PHP
yum -y install gd libxml2 libxml2-devel libjpeg-devel libpng-devel
tar zxvf php-5.3.28.tar.gz
cd php-5.3.28

./configure --prefix=/usr/local/php5/ --with-gd --with-zlib --with-mysql=/usr/local/mysql --with-config-file-path=/usr/local/php5 --enable-mbstring --enable-fpm  --with-jpeg-dir=/usr/lib
make && make install

测试：make test

2）安装后的调整
cp php.ini-development /usr/local/php5/php.ini
ln -s /usr/local/php5/bin/* /usr/local/bin/
ln -s /usr/local/php5/sbin/* /usr/local/sbin/

3)安装ZendGuardLoader
tar zxvf ZendGuardLoader-php-5.3-linux-glibc23-x86_64.tar.gz
cd ZendGuardLoader-php-5.3-linux-glibc23-x86_64/php-5.3.x/
cp ZendGuardLoader.so /usr/local/php5/lib/php/

vim /usr/local/php5/php.ini
zend_extension=/usr/local/php5/lib/php/ZendGuardLoader.so
zend_loader.enable=1

service nginx restart

3)配置Nginx支持PHP环境
1）启动php-fpm进程
cd /usr/local/php5/etc/

cp php-fpm.conf.default php-fpm.conf
useradd -M -s /sbin/nologin php

vim php-fpm.conf
pid = run/php-fpm.pid(去掉分号)
user = php
group = php
pm.start   20    
pm.min     5
pm.max     35
pm.max_children  50

启动php-fpm进程
/usr/local/sbin/php-fpm

netstat -apnt | grep php-fpm
netstat -apnt | grep nginx
netstat -apnt | grep mysqld

service nginx restart 或 reload

2）配置Nginx支持PHP解析
location ~ \.php$ {
            root           html;
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            #fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
            include        fastcgi.conf;
        }
3）php页面的测试访问
vim t.php
<?php
phpinfo();
?>

vim test.php
<?php 
$link=mysql_connect('localhost','root','pwd123');     //单引号
if($link)
echo "恭喜你，数据库连接成功！"; 
mysql_close();
?>
