Linux环境下安装Nginx-sky9890
操作系统：CentOS> 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
#
wget http://nginx.org/download/nginx-1.10.3.tar.gz
# tar -zxvf nginx-1.10.3.tar.gz
# cd nginx-1.10.3
# ls
autoCHANGESCHANGES.ruconfconfigurecontribhtmlLICENSEMakefilemanobjsREADMEsrc
2.编译安装Nginx
安装依赖包：
# yum install pcre-devel zlib-devel openssl-devel
#./configure \ #配置
--prefix=/usr/local/nginx \
--with-http_ssl_module
#make && make install #编译与安装
3.Nginx的启动与停止
Nginx启动
# cd /usr/local/nginx/sbin/
# ./nginx
# ps aux|grep ninx#ps命令查看Nginx运行状态
root 195990.00.0 103336 900 pts/0 S+ 08:38 0:00 grep ninx
立即停止服务：
# ./nginx-s stop
从容停止服务：
# ./nginx-s quit
通过kill或killall命令杀死进程
# killall nginx
# kill 19640 #kill nginx主进程PID
查看端口号占用：
# netstat-tlnup #查看端口号占用的情况
Active Internet connections (only servers)

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。
# ln -s /usr/local/nginx/sbin/nginx/usr/local/sbin/nginx
# nginx -s quit#停止Nginx服务
# nginx #启动Nginx服务
# nginx -s>#重新载入配置（平滑启动)
用一个shell脚本实现Nginx服务：
# 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"
;;
> echo "Reloading nginx daemon...."
$DAEMON -s> ;;
restart)
echo "Restaring nginx daemon..."
$DAEMON -s quit
$DAEMON && echo "SUCESS"
;;
*)
echo "Usage:service nginx{start|stop|restart|reload}"
exit 2
;;
esac
# chmod +x /etc/init.d/nginx #添加可执行权限
# chkconfig --add nginx #添加自启动操作
# chkconfig --level 2345 nginx on #设置启动级别
# nginx -t#检查语法
