在服务器中设置nginx开机启动

Nginx安装

使用yum安装nginx

yum install nginx

配置nginx开机启动
在/etc/init.d/下创建nginx文件，在该目录下创建的文件都会开机就执行

vi /etc/init.d/nginx

复制以下代码在刚刚创建的文件中

#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig:   - 85 15

设置/etc/init.d/nginx 执行权限

chmod 777 /etc/init.d/nginx

设置开机默认启动

chkconfig --add nginx //添加系统服务
chkconfig --level 345 nginx on //设置开机启动,启动级别
chkconfig --list nginx //查看开机启动配置信息

nginx控制命令

service nginx start   #开启
service nginx stop    #停止
service nginx restart #重启
service nginx reload  #重新加载

在/etc/nginx/nginx.conf 主配置文件的http块中加入这段命令，一般nginx配置文件是自带的，如果没有就加上吧。加上这段命令，在nginx启动时就会把conf.d中的配置文件也一起加载。

include /etc/nginx/conf.d/*.conf;

nginx实例配置

vi /etc/nginx/conf.d/flaskmovie_nginx.conf

复制以下内容

   upstream movie {
        server 127.0.0.1:5001;
        server 127.0.0.1:5002;
        server 127.0.0.1:5003;
        server 127.0.0.1:5004;
    }
    server {
        listen 8000;
        server_name localhost;
        location / {
            root html;
            index index.html index.htm;
            proxy_pass http://movie;
        }
        location ~ \.flv$ {
            flv;
            limit_rate 1024k;
            rewrite ^/static/upload/(.+?).flv$ /flask_movie/app/static/upload/$1.flv permanent;
        }
        location ~ \.mp4$ {
            mp4;
            limit_rate 1024k;
            rewrite ^/static/upload/(.+?).mp4$ /flask_movie/app/static/upload/$1.mp4 permanent;
        }
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
            root html;
        }
    }

这样服务器重启之后，就不用再去手动启动nginx或者去指定nginx的配置文件了。再加上上一篇文章的用supervisor管理uwsgi进程。以后重启服务器也不用做其他事，已经部署的网站也会在服务器重启之后重新执行。
