CentOS 7 sets up startup service and adds custom system services

• Create service file
• save directory
• Set auto-start at boot
• Other commands

---

1. Create service file

File path

<code>vim /usr/lib/systemd/<span>system</span>/nginx.service </code>

Service File content

<code><span>[Unit]</span><span>Description=<span>nginx - high performance web server</span></span><span>After=<span>network.target remote-fs.target nss-lookup.target</span></span><span>[Service]</span><span>Type=<span>forking</span></span><span>ExecStart=<span>/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf</span></span><span>ExecReload=<span>/usr/local/nginx/sbin/nginx -s reload</span></span><span>ExecStop=<span>/usr/local/nginx/sbin/nginx -s stop</span></span><span>[Install]</span><span>WantedBy=<span>multi-user.target</span></span></code>

Explanation of file content

<code>[<span>Unit</span>]:服务的说明<span>
Description:描述服务</span><span>
After:描述服务类别</span><span>
[Service]服务运行参数的设置</span><span>
Type=forking是后台运行的形式</span><span>
ExecStart为服务的具体运行命令</span><span>
ExecReload为重启命令</span><span>
ExecStop为停止命令</span><span>
PrivateTmp=True表示给服务分配独立的临时空间</span><span>
注意：启动、重启、停止命令全部要求使用绝对路径</span><span>
[Install]服务安装的相关设置，可设置为多用户</span></code>

2. Save the directory

Save in the directory with 754 permissions:

<code>/usr/lib/systemd/<span>system</span></code>

3. Set up auto-start on boot

Execute in any directory

<code>systemctl enable nginx<span>.service</span></code>

4. Other commands

Start nginx service

<code>systemctl <span><span>start</span> nginx.service</span></code>

Set up auto-start at boot

<code>systemctl enable nginx<span>.service</span></code>

Stop auto-start at boot

<code>systemctl disable nginx<span>.service</span></code>

View the current status of the service

<code>systemctl status nginx<span>.service</span></code>

Restart the service

<code>systemctl restart nginx<span>.service</span></code>

View all started services

<code>systemctl <span>list</span>-units --<span><span>type</span>=</span>service</code>

').addClass('pre-numbering ').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced CentOS 7 to set up startup services and add custom system services, including centos 7 content. I hope it will be helpful to friends who are interested in PHP tutorials.
