What this article shares with you is about how to configure linux sudo permissions. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

Record the simple sudo configuration process of linux and check it later.

1. Root, open the sudo configuration file

[root@centos ~] # visudo

2. Sudo configuration items

# # Next comes the main part: which users can run what software on

# # which machines (the sudoers file can be shared between multiple

# # systems).

# # Syntax:

# #

# # user MACHINE=COMMANDS

# #

# # The COMMANDS section may have other options added to it.

# #

# # Allow root to run any commands anywhere

Root ALL= (ALL) ALL

Mysql ALL= (ALL) ALL # configure all commands executed by the mysql user equivalent to the root user

3. Configure mysql secret-free execution

# # Read drop-in files from / etc/sudoers.d (the # here does not mean a comment)

# includedir / etc/sudoers.d

Mysql localhost= (root) NOPASSWD:ALL

4. Root changes the password of mysql

[root@centos ~] # passwd mysql

5. Mysql adds the sudo password of the mysql user. The sudo password is the password of the mysql operating system layer set in part 4.

-bash-4.1$ sudo uname

[sudo] password for mysql:

Linux

-bash-4.1 $

6. View sudo configuration

[root@centos ~] # sudo-l

Matching Defaults entries for root on this host:

Requiretty,! visiblepw, always_set_home, env_reset, env_keep= "COLORS DISPLAY HOSTNAME HISTSIZE INPUTRC KDEDIR LS_COLORS"

Env_keep+= "MAIL PS1 PS2 QTDIR USERNAME LANG LC_ADDRESS LC_CTYPE", env_keep+= "LC_COLLATE LC_IDENTIFICATION LC_MEASUREMENT

LC_MESSAGES ", env_keep+=" LC_MONETARY LC_NAME LC_NUMERIC LC_PAPER LC_TELEPHONE ", env_keep+=" LC_TIME LC_ALL LANGUAGE LINGUAS

_ XKB_CHARSET XAUTHORITY ", secure_path=/sbin\: / bin\: / usr/sbin\: / usr/bin

User root may run the following commands on this host:

(ALL) ALL

[root@centos ~] #

7. Mysql users test whether sudo is correct

-bash-4.1$ sudo mkdir / test1

-bash-4.1$ ls-l / test1

Total 0

-bash-4.1$ rm-rf / test1

Rm: cannot remove `/ test1': Permission denied

-bash-4.1$ sudo rm-rf / test1

-bash-4.1$ ls-l / test1

Ls: cannot access / test1: No such file or directory

-bash-4.1 $

The sudo configuration of linux is complete!
