以下为在root用户下安装mysql5.6.19&＃xff0c;然后升级到5.6.48的过程&＃xff0c;在root下操作非常简单&＃xff0c;且都是5.6系列只要简单执行rpm -ivh进行安装,rpm -Uvh 进行升级既可&＃xff0c;5.6只需要安装client包和service。mysql5.7系列和非root下的安装、升级&＃xff0c;后续会说到。

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER ! #注意这两句话&＃xff0c;告诉你默认密码放在哪
You will find that password in &＃39;/root/.mysql_secret&＃39;.

You must change that password on your first connect,
no other statement but &＃39;SET PASSWORD&＃39; will be accepted.
See the manual for the semantics of the &＃39;password expired&＃39; flag.

Also, the account for the anonymous user has been removed.

In addition, you can run:

  /usr/bin/mysql_secure_installation

which will also give you the option of removing the test database.
This is strongly recommended for production servers.

See the manual for more instructions.

New default config file was created as /usr/my.cnf and
