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 record is as follows: [root @ jwbdbalpha] # chkconfig & ndash; listyum-updatesdyum-update reported to the boss yesterday that our linux server is automatically updated every day and the boss is furious, it is very insecure to say that the production system cannot be like this. a senior engineer also mentioned that server update is also very cautious when he was moving. 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:
