通過systemctl命令執(zhí)行對系統(tǒng)服務的操作
systemctl [OPTIONS...] COMMAND [NAME...]
例如啟動網(wǎng)絡服務
systemctl start NetworkManager
CentOS7有兩個網(wǎng)絡服務棚品，其中network是為了兼容之前的版本黎侈，可以關(guān)掉network嚷炉，只啟動NetworkManager
systemctl stop network
systemctl restart NetworkManager
設置服務的開機自啟動
設置自啟動
systemctl enable NetworkManager
取消自啟動
systemctl disable NetworkManager
查看服務的自啟動情況,enable/disable/static,static依賴于其他服務的服務,本身不考慮是否自啟動
systemctl list-unit-files
[root@linux ~]# systemctl list-unit-files
