添加可执行权限：
|
1
|
chmod 754 /usr/lib/systemd/system/postgresql.service |
设置为开机自启动：
|
1
|
systemctl enable postgresql.service |
常用指令(以postgresql服务为例)：
启动某服务:
|
1
|
systemctl start postgresql.service |
停止某服务:
|
1
|
systemctl stop postgresql.service |
重启某服务:
|
1
2
|
systemctl restart postgresql.serviceservice postgresql restart |
使某服务自动启动(如tomcat服务):
|
1
|
systemctl enable postgresql.service |
使某服务不自动启动:
|
1
|
systemctl disable postgresql.service |
检查服务状态:
|
1
2
|
systemctl status postgresql.service （服务详细信息）systemctl is-active postgresql.service（仅显示是否Active) |
显示所有已启动的服务:
|
1
|
systemctl list-units --type=service |
