操作系统：CentOS release 6.9 (Final)
软件：nginx-1.10.3
任务：安装 Nginx
实战技巧：设置nginx自动启动服务
1.获取Nginx软件
[root@sky9890 tools]#
wget http://nginx.org/download/nginx-1.10.3.tar.gz
[root@sky9890 tools]# tar -zxvf nginx-1.10.3.tar.gz
[root@sky9890 tools]# cd nginx-1.10.3
[root@sky9890 nginx-1.10.3]# ls
auto CHANGES CHANGES.ru conf configure contrib html LICENSE Makefile man objs README src
2.编译安装Nginx
安装依赖包：
[root@sky9890 ~]# yum install pcre-devel zlib-devel openssl-devel
[root@sky9890 nginx-1.10.3]#./configure \ #配置
--prefix=/usr/local/nginx \
--with-http_ssl_module
[root@sky9890 nginx-1.10.3]#make && make install #编译与安装
3.Nginx的启动与停止
Nginx启动
[root@sky9890 /]# cd /usr/local/nginx/sbin/
[root@sky9890 sbin]# ./nginx
[root@sky9890 ~]# ps aux|grep ninx #ps命令查看Nginx运行状态
root 19599 0.0 0.0 103336 900 pts/0 S+ 08:38 0:00 grep ninx
立即停止服务：
[root@sky9890 sbin]# ./nginx -s stop
从容停止服务：
[root@sky9890 sbin]# ./nginx -s quit
通过kill或killall命令杀死进程
[root@sky9890 sbin]# killall nginx
[root@sky9890 sbin]# kill 19640 #kill nginx主进程PID
查看端口号占用：
[root@sky9890 sbin]# netstat -tlnup #查看端口号占用的情况

udp 0 0 0.0.0.0:123 0.0.0.0:* 1615/ntpd
优化配置：
创建软链接后，可以在任意目录下直接使用Nginx命令来控制Nginx服务。
[root@sky9890 ~]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/nginx
[root@sky9890 ~]# nginx -s quit #停止Nginx服务
[root@sky9890 ~]# nginx #启动Nginx服务
[root@sky9890 ~]# nginx -s reload #重新载入配置（平滑启动)
用一个shell脚本实现Nginx服务：
[root@sky9890 ~]# vi /etc/init.d/nginx
#!/bin/bash
#chkconfig: 35 85 15
DAEMON=/usr/local/nginx/sbin/nginx
case "$1" in
start)
echo "Starting nginx daemon..."
$ DAEMOM && echo "SUCCESS"
;;
stop)
echo "Stopping nginx daemon..."
$DAEMON -s quit && echo "SUCCESS"
;;
reload)
echo "Reloading nginx daemon...."
$DAEMON -s reload && echo "SUCCESS"
;;
restart)
echo "Restaring nginx daemon..."
$DAEMON -s quit
$DAEMON && echo "SUCESS"
;;
*)
echo "Usage:service nginx{start|stop|restart|reload}"
exit 2
;;
esac
[root@sky9890 ~]# chmod +x /etc/init.d/nginx #添加可执行权限
[root@sky9890 ~]# chkconfig --add nginx #添加自启动操作
[root@sky9890 ~]# chkconfig --level 2345 nginx on #设置启动级别
[root@sky9890 ~]# nginx -t #检查语法
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
[root@sky9890 ~]# nginx -v #检测版本
nginx version: nginx/1.10.3
[root@sky9890 ~]# nginx -V
