查看哪些是开机自启动服务
可以通过 chkconfig 命令查看
[root@linux30 ~]# chkconfig注：该输出结果只显示 SysV 服务，并不包含
原生 systemd 服务。SysV 配置数据
可能被原生 systemd 配置覆盖。要列出 systemd 服务，请执行 'systemctl list-unit-files'。查看在具体 target 启用的服务请执行'systemctl list-dependencies [target]'。netconsole 0:关 1:关 2:关 3:关 4:关 5:关 6:关
network 0:关 1:关 2:开 3:开 4:开 5:开 6:关
[root@linux30 ~]#如果是原生 systemd 服务，则可以使用 systemctl list-unit-files命令查看
[root@linux30 tidb]# systemctl list-unit-files

关闭开机自启动服务
方法1：
[root@linux30 tidb]# systemctl disable NAME...
# 示例：
[root@linux30 tidb]# systemctl disable tidb-4000.service
Removed symlink /etc/systemd/system/multi-user.target.wants/tidb-4000.service.
[root@linux30 tidb]#效果：
方法2：
针对具有集群管理工具的服务，可以使用其自带命令设置关闭
# 查看要禁用开机自启动的集群名称 ：tidb-cluster
