MYSQL主从+amoeba读写分离（一）

1.首先介绍下我的实验环境。

 System：     CentOS 6.0
              Master mysql： 192.168.3.161
              Slave mysql：  192.168.3.162
              Amoeba server：192.168.3.69

2.主从的配置

主服务器上添加同步用户
grant replication slave,file on *.* to 'replication'@'192.168.1.162' identified by '123456';  注：上面IP地址为从服务器的IP地址

flush privileges;

####修改master的my.cnf的配置

log-bin=mysql-bin         #打开mysql二进制日志
server-id= 1          #设置mysql_id，主从不能相同
binlog-do-db=test          #设置二进制日志记录的库
binlog-ignore-db=mysql        ##设置二进制日志不记录的库
sync_binlog=1      

####修改slave的my.cnf的配置

log-bin=mysql-bin
server-id= 2
replicate-do-db=test       #设置同步的库
replicate-ignore-db=mysql     #设置不同步的库
log-slave-updates           #同步后记录二进制日志
slave-skip-errors=all     
sync_binlog=1
slave-net-timeout=60

分别重启主从mysqld服务，登录主mysql，在主上执行flush tables with read lock;后将test数据库的数据copy到从上，并记录下主上show master status\G的结果：

如：

mysql> show master status\G;

*************************** 1. row ***************************

            File: mysql-bin.000022

            Position: 1237

           Binlog_Do_DB: test

           Binlog_Ignore_DB: mysql

然后执行unlock tables
登录从mysql，在从上执行：

stop slave;

change master to master_host='192.168.1.161',master_user='replication',master_password='123456',master_log_file='mysql-bin.000022',master_log_pos=1237;

start slave；

show slave status\G;

如果出现下面的情况，说明主从同步已经成功！
Slave_IO_Running: Yes
Slave_SQL_Running: Yes

3.Amoeba的配置安装

1）JDK环境的安装
下载jdk1.5或者更新版本,地址 http://java.sun.com/javase/downloads/index.jsp

我用的是：jdk-6u25-linux-i586-rpm.bin

在Amoeba server上执行

chmod 755 jdk-6u25-linux-i586-rpm.bin

./ jdk-6u25-linux-i586-rpm.bin

mv jdk1.6.0_25 /usr/local/jdk

添加变量

# vim /etc/profile

启动#amoeba start   (stop)

检查#ps aux | grep amoeba       # netstat -lnp | grep java

 

 

添加如下内容：

export JAVA_HOME=/usr/local/jdk

export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$PATH:$JAVA_HOME/bin

#. /etc/ profile

查看jdk   #java -version

 

2)安装配置amoeba

# mkdir /usr/local/amoeba

# tar zxvf amoeba-mysql-binary-2.0.1-BETA.tar.gz -C /usr/local/amoeba/

主要改2个配置文件，配置文件路径 /usr/local/amoeba/conf/

amoeba.xml
