nginx添加启动项

这篇博客介绍了如何在系统中新增Nginx服务,并设置为开机启动。内容包括编辑Nginx的启动脚本,赋予脚本执行权限,使用chkconfig添加启动项,以及查看和管理Nginx服务的状态。脚本详细展示了启动、停止、重启和重新加载配置的操作流程。

# 新增nginx
[my@xxxsbin]# vim /etc/inid.d/nginx
# 可执行文件
[root@xxxsbin]# chmod +x /etc/inid.d/nginx
# 添加启动项
[my@xxxsbin]# chkconfig nginx on
# 查看启动项
[my@xxxsbin]# chkconfig --list

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

netconsole     	0:off	1:off	2:off	3:off	4:off	5:off	6:off
network        	0:off	1:off	2:on	3:on	4:on	5:on	6:off
nginx          	0:off	1:off	2:on	3:on	4:on	5:on	6:off
redis          	0:off	1:off	2:on	3:on	4:on	5:on	6:off

nginx脚本如下:

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

# Check that networking is up.
