mysql一键部署脚本，亲测可用，附安装包

脚本运行的环境：

①防火墙及SElinux关闭

②centos7.9

③外网通

废话少说，直接附脚本

# Example MySQL config file for medium systems.  
  #  
  # This is for a system with little memory (32M - 64M) where MySQL plays  
  # an important part, or systems up to 128M where MySQL is used together with  
  # other programs (such as a web server)  
  #  
  # MySQL programs look for option files in a set of  
  # locations which depend on the deployment platform.  
  # You can copy this option file to one of those  
  # locations. For information about these locations, see:  
  # http://dev.mysql.com/doc/mysql/en/option-files.html  
  #  
  # In this file, you can use all long options that a program supports.  
  # If you want to know which options a program supports, run the program  
  # with the "--help" option.

    # Replication Slave (comment out master section to use this)  
    #  
    # To configure this host as a replication slave, you can choose between  
    # two methods :  
    #  
    # 1) Use the CHANGE MASTER TO command (fully described in our manual) -  
    #    the syntax is:  
    #  
    #    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,  
    #    MASTER_USER=, MASTER_PASSWORD= ;  
    #  
    #    where you replace , ,  by quoted strings and  
    #     by the master's port number (3306 by default).  
    #  
    #    Example:  
    #  
    #    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,  
    #    MASTER_USER='joe', MASTER_PASSWORD='secret';  
    #  
    # OR  
    #  
    # 2) Set the variables below. However, in case you choose this method, then  
    #    start replication for the first time (even unsuccessfully, for example  
    #    if you mistyped the password in master-password and the slave fails to  
    #    connect), the slave will create a master.info file, and any later  
    #    change in this file to the variables' values below will be ignored and  
    #    overridden by the content of the master.info file, unless you shutdown  
    #    the slave server, delete master.info and restart the slaver server.  
    #    For that reason, you may want to leave the lines below untouched  
    #    (commented) and instead use CHANGE MASTER TO (see above)  
    #  
    # required unique id between 2 and 2^32 - 1  
    # (and different from the master)  
    # defaults to 2 if master-host is set  
    # but will not function as a slave if omitted  
    #server-id       = 2  
    #  
    # The replication master for this slave - required  
    #master-host     =     
    #  
    # The username the slave will use for authentication when connecting  
    # to the master - required  
    #master-user     =

    # The password the slave will authenticate with when connecting to  
    # the master - required
