systemctl管理nginx启动或重新启动卡住问题处理-工具盒子

概述

项目中安装部署最新nginx后由开发修改对应配置文件。在启动和重新启动nginx发现systemctl命令卡住无输出，在终止命令后发现服务实际已经运行。

解决办法

由于Nginx为yum安装，默认的pid文件路径是/run/nginx.pid，开发修改了nginx中的默认pid文件路径。导致systemctl命令无法读取到pid内容以至于夯住。

[root@localhost ~]# vi /usr/lib/systemd/system/nginx.service
[Unit]
Description=The nginx HTTP and reverse proxy server
After=network-online.target remote-fs.target nss-lookup.target
Wants=network-online.target

\[Service\]
Type=forking
PIDFile=/run/nginx.pid


Nginx will fail to start if /run/nginx.pid already exists but has the wrong

SELinux context. This might happen when running `nginx -t` from the cmdline.

ExecStartPre=/usr/bin/rm -f /run/nginx.pid

修改PIDFile=路径为Nginx配置文件中的pid路径即可解决。
