设置nginx开机启动

た入场券 2022-05-21 07:47 419阅读 0赞

**本文目标**

设置完成后，可以通过 /etc/init.d/nginx start 或者 service nginx start的方式启动nginx。

**准备工作**

查看linux服务器上nginx存放的目录(通过whereis nginx或者find / -name nginx命令查找)，记录下来，如：

nginx命令目录为：/usr/local/nginx/sbin/nginx

nginx.conf目录为: /usr/local/nginx/conf/nginx.conf

**开始**

# cd /etc/init.d
    # 新建nginx文件
    # touch nginx
    # 改变该文件权限(由于该目录中几乎所有文件都是755权限,所以将nginx也设置为755)
    # chmod 755 nginx
    # chkconfig --add nginx
    # 设置开机启动
    # chkconfig --level 2345 nginx on
    # 编辑nginx文件
    # vi nginx

在文本编辑器中将以下代码复制进去，修改其中的nginx命令和nginx.conf配置文件位置

注: 以下代码来自官网 [https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/][https_www.nginx.com_resources_wiki_start_topics_examples_redhatnginxinit], 可到官网查看最新版本信息，并复制粘贴修改。

根据本地的实际路径，将代码中的:

nginx="/usr/sbin/nginx" 改为 nginx="/usr/local/nginx/sbin/nginx"

NGINX\_CONF\_FILE="/etc/nginx/nginx.conf" 改为 NGINX\_CONF\_FILE="/usr/local/nginx/conf/nginx.conf"

最后将这个改动的文件全部内容复制粘贴到nginx文件内，:wq保存即可

**测试**

# service nginx status
    nginx (pid 6799 6798) is running...
    # service nginx stop
    Stopping nginx:                                            [  OK  ]
    # service nginx start
    Starting nginx:                                            [  OK  ]
