一、LNMP架构简介
LNMP平台就是Linux、Ngnix、MySQL、PHP的组合架构，需要Linux服务器、MySQL数据库、PHP解析环境
Nginx是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。Mysql是一个小型关系型数据库管理系统。PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。
二、Nginx编译安装
1 [root@localhost ~]# yum -y install gcc gcc-c++ make pcre-devel zlib-devel
2
3 [root@localhost ~]# tar zxf nginx-1.12.2.tar.gz
4 [root@localhost ~]# cd nginx-1.12.2/
5 [root@localhost nginx-1.12.2]# ./configure
6 --prefix=/usr/local/nginx
7 --user=nginx
8 --group=nginx
9 --with-http_stub_status_module ###统计状态模块
10
11 [root@localhost nginx-1.12.2]# make && make install
12
13 [root@localhost ~]# useradd -M -s /sbin/nologin nginx ###创建一个不可登录的程序用户
14
15 [root@localhost ~]# ln -s /usr/local/nginx/sbin/nginx /usr/bin ###优化执行路径
16 [root@localhost ~]# nginx ###启动服务
17 [root@localhost ~]# netstat -anpt | grep nginx ###查看nginx服务是否开启
18 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 16429/nginx: master
19
20 [root@localhost ~]# killall -s QUIT nginx ###选项-s QUIT等于-3 停止服务
21 [root@localhost ~]# netstat -anpt | grep nginx
22
23 [root@localhost ~]# killall -s HUP nginx ###选项-s HUP等于-1 重新加载
24 [root@localhost ~]# netstat -anpt | grep nginx
25 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 16488/nginx: master
26
27 [root@localhost ~]# vi /etc/init.d/nginx ###制作管理脚本
28 #!/bin/bash
29 #chkconfig: 35 20 80
30 #description: nginx server
31 PROG="/usr/local/nginx/sbin/nginx"
32 PIDF="/usr/local/nginx/logs/nginx.pid"
33
34 case "$1" in
35 start)
36 $PROG
37 ;;
38 stop)
39 killall -s QUIT $(cat $PIDF)
40 ;;
41 restart)
42 $0 stop
43 $0 start
44 ;;
45 reload)
46 killall -s HUP $(cat $PIDF)
47 ;;
48 *)
49 echo "Usage: $0 {start|stop|reload|status}"
50 exit 1
51 esac
52 exit 0
