mysql amoeba 读写分离
- - 数据库 - ITeye博客本文在Mysql主从同步的基础上进行配置. 不熟悉的盆友请自行乘坐时光机. Mysql主从同步:http://nothing-whoami.iteye.com/blog/2144294. 再加一台主机 amoeba : 192.168.10.21. 二、解压并修改amoeba配置文件. 这里如果插入的话就会插到 192.168.10.17,读数据的话就会读到 192.168.10.20.
本文在Mysql主从同步的基础上进行配置
不熟悉的盆友请自行乘坐时光机。 Mysql主从同步:http://nothing-whoami.iteye.com/blog/2144294
再加一台主机 amoeba : 192.168.10.21
一、下载amoeba
wget http://nchc.dl.sourceforge.net/project/amoeba/Amoeba%20for%20mysql/2.x/amoeba-mysql-binary-2.1.0-RC5.tar.gz
二、解压并修改amoeba配置文件

./amoeba start & [1] 20516 wolfplus@jianghanyou:~/nothing/amoeba/bin$ log4j:WARN log4j config load completed from file:/home/wolfplus/nothing/amoeba/conf/log4j.xml 2014-10-17 16:18:35,197 INFO context.MysqlRuntimeContext - Amoeba for Mysql current versoin=5.1.45-mysql-amoeba-proxy-2.1.0-RC5 log4j:WARN ip access config load completed from file:/home/wolfplus/nothing/amoeba/conf/access_list.conf 2014-10-17 16:18:35,482 INFO net.ServerableConnectionManager - Amoeba for Mysql listening on 0.0.0.0/0.0.0.0:8066. 2014-10-17 16:18:35,489 INFO net.ServerableConnectionManager - Amoeba Monitor Server listening on /127.0.0.1:25475.
4 登陆方式
mysql -unothing -p123456 -h192.168.10.21 -P8066
这里如果插入的话就会插到 192.168.10.17,读数据的话就会读到 192.168.10.20 。测试时请先停止主从模式。在从机插入数据,再进行试验。
写的简单了点!这是主要的操作过程。至于更详细的!这里推荐两个链接吧
