请教洞哥,famp的mysql的my.ini 在那里？？找了半天我也没找到

mimi

FREEBSD系统下的mysql没有这个文件吗/

mimi

如果卢优化一下mysql的性能， 是改这个文件吗？？
大至有那些可行的办法来提高mysql的性能？？

爱洞特漏

/etc/my.cnf

mimi

洞哥， 如果要优化mysql性能的话， 大概要改什么参数呢？？
服务器主要跑论坛， 现在论坛一天发贴量在2W左右
cpu进程主要mysql进程高，大概占百分之10
php-fcgi和nginx的进程基本上占用不到百分之二

61. # To configure this host as a replication slave, you can choose between
    
62. # two methods :
    
63. #
    
64. # 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    
65. # the syntax is:
    
66. #
    
67. # CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
    
68. # MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
    
69. #
    
70. # where you replace <host>, <user>, <password> by quoted strings and
    
71. # <port> by the master's port number (3306 by default).
    
72. #
    
73. # Example:
    
74. #
    
75. # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
    
76. # MASTER_USER='joe', MASTER_PASSWORD='secret';
    
77. #
    
78. # OR
    
79. #
    
80. # 2) Set the variables below. However, in case you choose this method, then
    
81. # start replication for the first time (even unsuccessfully, for example
    
82. # if you mistyped the password in master-password and the slave fails to
    
83. # connect), the slave will create a master.info file, and any later
    
84. # change in this file to the variables' values below will be ignored and
    
85. # overridden by the content of the master.info file, unless you shutdown
    
86. # the slave server, delete master.info and restart the slaver server.
    
87. # For that reason, you may want to leave the lines below untouched
    
88. # (commented) and instead use CHANGE MASTER TO (see above)
    
89. #
    
90. # required unique id between 2 and 2^32 - 1
    
91. # (and different from the master)
    
92. # defaults to 2 if master-host is set
    
93. # but will not function as a slave if omitted
    
94. #server-id = 2
    
95. #
    
96. # The replication master for this slave - required
    
97. #master-host = <hostname>
    
98. #
    
99. # The username the slave will use for authentication when connecting
    
100. # to the master - required
     
101. #master-user = <username>
     
102. #
     
103. # The password the slave will authenticate with when connecting to
     
104. # the master - required
     
105. #master-password = <password>
     
106. #
