LNMP平臺搭建

基本配置：
操作系統爲：CentOS 7.2

[root@localhost qwe]# cat /etc/redhat-release CentOS Linux release
7.2.1511 (Core)

確定主機名：LNMP

vim /etc/hostname

確定IP地址：192.168.0.195

ip a
/etc/sysconfig/network-scripts/ifcfg-eth0

關閉防火牆：service iptables stop

一、配置Nginx網站服務

1.運行Nginx需要pcre、zilib等軟件包支持，先安裝開發包

[root@LNMP qwe]# yum -y install pcre-devel zlib-devel

2.創建運行的用戶和組

[root@LNMP qwe]# useradd -M -s /sbin/nologin nginx //不指定宿主目錄且禁止登錄shell
[root@LNMP qwe]# id nginx
uid=1000(nginx) gid=1000(nginx) 組=1000(nginx)

3.編譯安裝Nginx

[root@LNMP ~]# tar zxvf nginx-1.10.1.tar.gz
[root@LNMP nginx-1.10.1]# ls
auto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src
[root@LNMP nginx-1.10.1]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module 
./configure: error: C compiler cc is not found       //這個錯誤是你沒有安裝c語言編輯器
[root@LNMP nginx-1.10.1]# yum -y install gcc* gcc-*
[root@LNMP nginx-1.10.1]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module
          ###  http_stub_status_module      //添加狀態統計模塊
[root@LNMP nginx-1.10.1]# make && make install
[root@LNMP nginx-1.10.1]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
[root@LNMP nginx-1.10.1]# ls -l /usr/local/sbin/nginx 
lrwxrwxrwx. 1 root root 27 Jul 19 08:07 /usr/local/sbin/nginx -> /usr/local/nginx/sbin/nginx

執行nginx –t可以檢查配置文件nginx.conf中的錯誤

[root@LNMP ~]# nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

4.直接執行nginx運行服務

[root@LNMP qwe]# ngxin
[root@LNMP qwe]# netstat -anpt | grep nginx
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      4790/nginx: master  
Killall –s HUP nginx                    //HUP表示重載配置
Killall –s QUIT nginx                   //QUIT表示退出進程

5.編寫Nginx服務控制腳本

[root@LNMP qwe]# touch /etc/init.d/nginx
[root@LNMP qwe]# 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
  ;;
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

[root@LNMP qwe]# chmod +x /etc/init.d/nginx 
[root@LNMP qwe]# chkconfig --add nginx
[root@LNMP qwe]# chkconfig --list nginx
nginx           0:關 1:關 2:關 3:開 4:關 5:開 6:關

6.Nginx的訪問狀態統計

[root@LNMP qwe]# vim /usr/local/nginx/conf/nginx.conf
#user  nobody;                                          //默認用戶nobody
worker_processes  1;                                        //工作進程數量
#error_log  logs/error.log;                                 //錯誤日誌文件位置
#pid        logs/nginx.pid;                                 //PID文件位置

events {
    use epoll;                                              //啓用epoll模型
    worker_connections  1024;                               //每進程處理連接數量
}
    http {
      ······
 server {
        listen       80;                                //監聽端口默認80
        server_name  www.benet.com;                 //網站名稱
        charset utf-8;                                  //網站默認字符集

        location / {                                    //根目錄配置
            root   html;                                //網站根目錄
            index  index.html index.htm;                //默認首頁
        }

        location /status {                              //訪問位置/status
            stub_status           on;                   //開啓status統計功能
            access_log          off;                    //關閉此位置的日誌記錄
        }

        error_page   500 502 503 504  /50x.html;            //內部錯誤的反饋頁面
        location = /50x.html {                          //錯誤頁面配置
            root   html;
        }
        }
｝
[root@Nginx ~]# /etc/init.d/nginx reload
使用客戶機訪問www.benet.com/status   //如果域名訪問的話，需要在客戶機加上映射
