supervisor管理nginx

supervisor配置文件/etc/supervisor/supervisord.conf中定义了include,因此如果想要管理服务,就需要编辑/etc/supervisor/config.d/*.ini文件

[include] 
files = /etc/supervisor/config.d/*.ini

编辑nginx服务配置文件/etc/supervisor/config.d/nginx.ini

⚠️需要注意的是/usr/sbin/nginx表示在后台运行,但是supervisor不能监控后台程序, 所以supervisor就一直执行这个命令 ,因此会报错

/usr/sbin/nginx后必须加参数 -g 'daemon off;' 表示在前台运行

cat >/etc/supervisor/config.d/nginx.ini<<'EOF'
[program:nginx]
# use default nginx config file and dir
command = /usr/sbin/nginx -g 'daemon off;'
stdout_logfile = /var/log/supervisor/nginx.log
redirect_stderr = true
autorestart = true
EOF

将nginx加入supervisor

$ supervisorctl update nginx
nginx: added process group

查看状态

$ supervisorctl status nginx
nginx           RUNNING   pid 9464, uptime 0:00:03

详细配置

[program:nginx]
# use default nginx config file and dir
command = /usr/local/nginx/sbin/nginx -g 'daemon off;'
stdout_logfile = /var/log/supervisord/nginx.log
redirect_stderr = true
autorestart = true
