RHEL6 MySQL5.7 Amoeba部署

Posted 2021-02-16 okchy

Amoeba部署文档

一、环境说明

系统：Red Hat Enterprise Linux Server release 6.3

192.168.24.90 Amoeba

192.168.24.91 mysql5.7.25 主库

192.168.24.92 MySQL5.7.25 从库

主从replication配置完成

 

 

 

二、安装

3.1 配置授权用户

在主库中添加授权用户，通过mycat代理到主库服务器只能使用DML语句

grant select,insert,update,delete on *.* to ‘amoeba‘@‘%‘ identified by ‘password‘;

flush privileges;

 

从库中收回授权用户权限

Revoke insert,update,delete on *.* from ‘amoeba’@’%’;

flush privileges;

 

3.2 Amoeba服务器配置JDK

3.2.1 安装JDK1.7，JDK版本必须高于1.7

查看当前JDK版本：java -version

低于1.7查看当前安装RPM包详细信息：rpm -qa | grep java

rpm -e –-nodeps RPM包 #卸载目前javaRPM包

rpm -ivh jdk-1.7版本.rpm #安装jdk1.7版本RPM包

mkdir /usr/local/java

解压后的jdk文件夹移动到/usr/local/java

/etc/profile追加变量

export PATH=/usr/local/mysql/bin:$PATH

export JAVA_HOME=/usr/local/java/jdk1.7版本

export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH

检查java版本 java –version

 

3.2.2 配置amoeba

mkdir /usr/local/amoeba

将解压后的amoeba文件复制到/usr/local/amoeba中

/usr/local/amoeba/conf/amoeba.xml配置

注意：真实数据库中schema的库名必须存在

3.2.3启动前准备

编辑usr/local/amoeba/bin/amoeba修改DEFAULT_OPTS行

DEFAULT_OPTS="-server -Xms256m -Xmx256m -Xss256k"

chmod 700 -R /usr/local/amoeba/bin/

 

3.3 启动Amoeba

/usr/local/amoeba/bin/amoeba&

 

三、验证

从库运行

mysql -uroot -ppassword -h192.168.24.90 -P8066 进入Amoeba代理服务器

select sleep(10);

分别在主库和从库执行show processlist查看线程

192.168.24.91 没有select线程

192.168.24.92 有select线程

实现主从读写分离功能
