74. # To configure this host as a replication slave, you can choose between
    
75. # two methods :
    
76. #
    
77. # 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    
78. #    the syntax is:
    
79. #
    
80. #    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
    
81. #    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
    
82. #
    
83. #    where you replace <host>, <user>, <password> by quoted strings and
    
84. #    <port> by the master's port number (3306 by default).
    
85. #
    
86. #    Example:
    
87. #
    
88. #    CHANGE MASTER TO MASTER_HOST='*.*.*.*', MASTER_PORT=3306,
    
89. #    MASTER_USER='joe', MASTER_PASSWORD='secret';
    
90. #
    
91. # OR
    
92. #
    
93. # 2) Set the variables below. However, in case you choose this method, then
    
94. #    start replication for the first time (even unsuccessfully, for example
    
95. #    if you mistyped the password in master-password and the slave fails to
    
96. #    connect), the slave will create a master.info file, and any later
    
97. #    change in this file to the variables' values below will be ignored and
    
98. #    overridden by the content of the master.info file, unless you shutdown
    
99. #    the slave server, delete master.info and restart the slaver server.
    
100. #    For that reason, you may want to leave the lines below untouched
     
101. #    (commented) and instead use CHANGE MASTER TO (see above)
     
102. #
     
103. # required unique id between 2 and 2^32 - 1
     
104. # (and different from the master)
     
105. # defaults to 2 if master-host is set
     
106. # but will not function as a slave if omitted
     
107. #server-id       = 2
     
108. #
     
109. # The replication master for this slave - required

111. #
     
112. # The username the slave will use for authentication when connecting
     
113. # to the master - required

几年前的服务器了，上面东西很多，不好迁移啊 怕出问题。。
另外关于mysql优化网上说法千人千面。。

好纠结

可乐呀

上centos7和mysql5.7吧、、、、

the2ndface

楼上说的对，当然，如果早期数据需要迁移，用的是这个版本，那还是继续用吧

5.1。。都8.0了。最起码也5
