谁给个优化好的512以上的my.cnf啊

qdfushuai

天啊所有的一键包都是针对128优化的。。。。限制的死死的对于菜鸟的我来说太难了。。。谁给个配置好的512-1g的配置文件啊

咯拉无米

shinko

新版本已经添加简易的增加多站点脚本了,命令是: ./host.sh
你去看看吧

mysql优化还是靠自己的,128的优化只是优化内存小点,而不是优化性能的

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

楼主 修改这2个位置，就好明显了：

# The MySQL server
[mysqld]
skip-locking
key_buffer_size = 256M
table_open_cache = 256

我256M的，keyburffersize我设置是4M （小内存好多设置成16k，差别太大）
table这个，我设置成64，应该来说64足够了

这样弄下来，内存占用还不错，而且性能也OK，楼主可以细细调节以上2个参数，慢慢看看对网站影响大不大

金满堂

直接用默认的 share/mysql/my-medium.cnf

覆盖到 /etc/my.cnf 下

应该行..
