mysql 用戶免密執行root命令方法

說明： sudo命令的執行流程是: 當前用戶轉換到root, 然後以root身份執行命令, 執行完成後, 直接退回到當前用戶. 需要注意的是: 執行sudo時輸入的密碼, 是當前用戶的密碼, 並非root密碼 1、修改文件寫權限 # ls -l /etc/sudoers -r--r----- 1 root root 4042 Nov 4 15:05 /etc/sudoers # chmod u+x /etc/sudoers # vi /etc/sudoers # ls -l /etc/sudoers 2、添加免密用戶 vi /etc/sudoers ## Allow root to run any commands anywhere root ALL=(ALL) ALL ## add mysql user mysql ALL=(ALL) NOPASSWD: ALL 3、sudo免密測試 [mysql@devdb01 ~]$ sudo ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:50:56:87:3b:bd brd ff:ff:ff:ff:ff:ff inet 1x2.55.3.xx/24 brd 196.55.3.255 scope global eth0 inet6 fe80::250:56ff:fe87:3bbd/64 scope link valid_lft forever preferred_lft forever [mysql@devdb01 ~]$
