Disable Automatic centos update

Yesterday, I reported to my boss that our Linux server was automatically updated every day. The boss was furious and said that the production system could not be like this and it was very insecure. A senior brother also said that when he was moving, server updates are also very cautious. It seems that my thinking is too technical and not comprehensive enough, so I will turn off automatic update when I come back.

The operation records are as follows:

[[Email protected] Alpha] # chkconfig-list Yum-updatesd

Yum-updatesd 0: Disable 1: Disable 2: Enable 3: Enable 4: Enable 5: Enable 6: Disable

[[Email protected] Alpha] # service Yum-updatesd stop

Stop Yum-updatesd: [OK]

[[Email protected] Alpha] # service Yum-updatesd status

Yum-updatesd stopped

[[Email protected] Alpha] # chkconfig-level 35 Yum-updatesd off

[[Email protected] Alpha] # chkconfig-list Yum-updatesd

Yum-updatesd 0: Disable 1: Disable 2: Enable 3: Disable 4: Enable 5: Disable 6: Disable
