军哥进来帮忙下。谢谢。。MYsql重启出错。

winson

今天就因为SENDMAIL失效。重新安装的时候。发现有200多个东西没有升级。就输入

apt-get update.
apt-ge

rt upgrade

接下来重启lnmp就出现这种情况了

62. # To configure this host as a replication slave, you can choose between
    
63. # two methods :
    
64. #
    
65. # 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    
66. #    the syntax is:
    
67. #
    
68. #    CHANGE MASTER TO MASTER_HOST=, MASTER_PORT=,
    
69. #    MASTER_USER=, MASTER_PASSWORD= ;
    
70. #
    
71. #    where you replace , ,  by quoted strings and
    
72. #     by the master's port number (3306 by default).
    
73. #
    
74. #    Example:
    
75. #
    
76. #    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
    
77. #    MASTER_USER='joe', MASTER_PASSWORD='secret';
    
78. #
    
79. # OR
    
80. #
    
81. # 2) Set the variables below. However, in case you choose this method, then
    
82. #    start replication for the first time (even unsuccessfully, for example
    
83. #    if you mistyped the password in master-password and the slave fails to
    
84. #    connect), the slave will create a master.info file, and any later
    
85. #    change in this file to the variables' values below will be ignored and
    
86. #    overridden by the content of the master.info file, unless you shutdown
    
87. #    the slave server, delete master.info and restart the slaver server.
    
88. #    For that reason, you may want to leave the lines below untouched
    
89. #    (commented) and instead use CHANGE MASTER TO (see above)
    
90. #
    
91. # required unique id between 2 and 2^32 - 1
    
92. # (and different from the master)
    
93. # defaults to 2 if master-host is set
    
94. # but will not function as a slave if omitted
    
95. #server-id       = 2

已经解决，更新下MYSQL版本或者重新安装一键包。。
