In the jumpserver, the system user needs to be set. It can be directly set as the root user with full permissions, but this risk is also relatively high. The user can create users and delete files, so we need to deal with different employees. , Assign different system users, or each employee establishes a system user, and then set permissions

Setting a root permission is
simple, just add a root user, and set the permissions of / bin / su, which is equivalent to giving administrator permissions. After logging in to jumpserver, this user can directly perform root operations on the machine .
/bin/susystem user
Parameter description! / Bin / su Disable sudo su-switch to root This is very important, if you don't want them to be able to do sudo su-operation you need to add !/bin/su

Login test rules
After we landed a springboard to the machine, the user becomes a huangcong, then need to do is sudo su -switch to an administrator, then perform dangerous operations, you will find, not just delete the root of this dangerous operation.
