主从配置使用通用二进制包版本为MySQL5.7.26。三台服务器均关闭防火墙和SELINUX。
一、主机A和主机B做主从同步
1、安装MySQL
# tar xf mysql-5.7.26-linux-glibc2.5-x86_64.tar.gz
# useradd -M -s /sbin/nologin mysql
# yum -y install libaio-devel
# mv mysql-5.7.26-linux-glibc2.5-x86_64/ /usr/local/mysql
# /usr/local/mysql/scripts/mysql_install_db --usermysql --datadir/usr/local/mysql/data/ --basedir/usr/local/mysql/
# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
# vim /etc/my.cnf
[mysqld]
datadir/usr/local/mysql/data
socket/tmp/mysql.sock
usermysql
symbolic-links0
[mysqld_safe]
log-error/var/log/mysqld.log
pid-file/var/run/mysqld/mysqld.pid
# service mysqld start
# chkconfig mysqld on
# mysql -uroot password
# echo PATH${PATH}:/usr/local/mysql/bin /etc/profile
# source /etc/profile
# ss -tunlp | grep 3306 2、配置主从同步
①主机A配置
# vim /etc/my.cnf
server-id1
log-binmysql-bin
log-bin-indexmysql-bin.index
max-binlog-size100M
# service mysqld restart
# mysql -u root –p
mysql GRANT ALL PRIVILEGES ON *.* TO wdd192.168.131.% IDENTIFIED BY 123456;
mysql FLUSH PRIVILEGES;
mysql SHOW MASTER STATUS; ②主机B配置
# vim /etc/my.cnf
server-id2
relay-logrelay-bin
relay-log-info-filerelay-log.info
# service mysqld restart
# mysql -u root –p
mysql CHANGE MASTER TO
MASTER_HOST192.168.131.129,
MASTER_USERwdd,
MASTER_PASSWORD123456,
MASTER_LOG_FILEmysql-bin.000001,
MASTER_LOG_POS405;
mysql START SLAVE;
mysql SHOW SLAVE STATUS\G; mysql GRANT ALL PRIVILEGES ON *.* TO wdd192.168.131.% IDENTIFIED BY 123456;
mysql FLUSH PRIVILEGES;
二、主机C作为中间件
1、搭建amoeba运行环境
# mkdir /amoeba
# tar xf jdk-7u40-linux-x64.gz -C /amoeba/
# vim /etc/profile
JAVA_HOME/amoeba/jdk1.7.0_40
export JAVA_HOME
PATH$JAVA_HOME/bin:$PATH
export PATH
CLASSPATH.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$CLASSPATH
export CLASSPATH
# source /etc/profile
# yum -y install java
# java –version
2、安装amoeba
# unzip amoeba-mysql-1.3.1-BETA.zip -d /usr/local/amoeba
# chmod -R x /usr/local/amoeba/bin/
3、配置amoeba文件
# cd /usr/local/amoeba/conf/
# vim amoeba.xml
?xml version1.0 encodinggbk?
!DOCTYPE amoeba:configuration SYSTEM amoeba.dtd
amoeba:configuration xmlns:amoebahttp://amoeba.meidusa.com/

一台mysqlServer 需要配置一个pool
如果多台 平等的mysql需要进行loadBalance
平台已经提供一个具有负载均衡能力的objectPoolcom.meidusa.amoeba.mysql.server.MultipleServerPool
简单的配置是属性加上 virtualtrue,该Pool 不允许配置factoryConfig
或者自己写一个ObjectPool。

4、修改log4j.xml 取消日志文件生成太大了磁盘很容易满
# vim log4j.xml
param namefile value${amoeba.home}/logs/project.log/
改成
param namefile value![CDATA[${amoeba.home}/logs/project.log/dev/null]]/
5、修改amoeba启动脚本
# vim /usr/local/amoeba/bin/amoeba
DEFAULT_OPTS-server -Xms256m -Xmx256m -Xss128k
改为
DEFAULT_OPTS-server -Xms256m -Xmx256m -Xss256k
6、启动Amoeba脚本
# nohup bash -x /usr/local/amoeba/bin/amoeba #放入后台运行
# cat nohup.out #查看日志看是否启动成功
# ps -ef | grep amoeba | grep -v grep #查看进程是否启动成功 三、测试读写分离是否成功
1、主机C
# yum -y install mysql
# mysql -u root -p -P 8066 -h 192.168.131.136 2、主机A主服务器操作
# mysql -u root –p
mysql use test;
mysql create table info(
id int(10) unsigned not null auto_increment primary key,
name char(20));
mysql show tables; 3、主机B从服务器操作
# mysql -u root –p
mysql use test;
mysql show tables; mysql STOP SLAVE; #为了看到试验结果停止从服务器
4、主机A操作
mysql insert into info values (1,master);
5、主机B操作
mysql insert into info values (2,slave);
6、主机C进行测试
mysql use test; #进行读操作
mysql select * from info; mysql insert into info values (3,wdd);
7、主机A进行操作
mysql select * from info; #进行写操作查询
