文件夹位置

一些可能的文件夹位置:

Ubuntu 18.04.2 LTS: /lib/systemd/system

CentOS Linux 7 (Core): /usr/lib/systemd/system

使用方法

  1. sudo systemctl daemon-reload
  2. sudo systemctl start redis
  3. sudo systemctl status redis

自动启动

# 成功后将显示:
# /etc/systemd/system/multi-user.target.wants/mongod.service → /lib/systemd/system/mongod.service
# 然后可实现开机自动启动
sudo systemctl enable mongod
