Mycat+MySQL 主从复制

一、主从复制搭建(新环境5.6.33)
1、设置复制Master配置信息

[mysqld]
#repl master库
server-id=6
log-bin=E:\MySQL\4306\logbin\mysql-bin
max_binlog_size=100M
binlog-format=MIXED

2、启动Master实例
3、Master实例上创建一个用于复制的帐户

mysql> use `mysql`;
mysql> GRANT REPLICATION SLAVE ON *.* TO 'repl'@'localhost' IDENTIFIED BY 'repl';

4、获取Master状态信息

#在session1锁表
mysql> FLUSH TABLES WITH READ LOCK;
#在session2查看状态
mysql > SHOW MASTER STATUS;

5、在Master上释放读锁

mysql> UNLOCK TABLES;

6、在Slave上编辑配置信息

[mysqld]
#repl slave库
server-id=7
relay_log=E:\MySQL\4307\logbin\mysql-relay-bin

7、启动Slave实例
8、在Slave上设置Master配置

mysql> change master to
master_host='127.0.0.1',
master_port=4306,
master_user='repl',
master_password='repl',
master_log_file='mysql-bin.000001',
master_log_pos=331;

二、Mycat搭建
Mycat、Mycat-eye依赖jdk1.7+环境
1、JDK下载安装(jdk-7u80-windows-i586.exe)，并配置环境变量

新创建环境变量(变量名+变量值)
JAVA_HOME
D:\Java\jdk1.7.0_80
Classpath
.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar
MYCAT_HOME
D:\MySQLSoftware\mycat
PATH添加值
;%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;%MYCAT_HOME%\bin

设置环境变量后cmd运行

java -version

2、Mycat解压(Mycat-server-1.6-RELEASE-20161028204710-win.tar.gz)，运行startup_nowrap.bat

rem startup_nowrap.bat
REM check JAVA_HOME & java
set "JAVA_CMD=%JAVA_HOME%\bin\java"
if "%JAVA_HOME%" == "" goto noJavaHome
if exist "%JAVA_HOME%\bin\java.exe" goto mainEntry
:noJavaHome
echo ---------------------------------------------------
echo WARN: JAVA_HOME environment variable is not set. 
echo ---------------------------------------------------
set "JAVA_CMD=java"
:mainEntry
REM set HOME_DIR
set "CURR_DIR=%cd%"
cd ..
set "MYCAT_HOME=%cd%"
cd %CURR_DIR%
"%JAVA_CMD%" -server -Xms512M -Xmx1024M -XX:MaxPermSize=64M  -XX:+AggressiveOpts -XX:MaxDirectMemorySize=1G -DMYCAT_HOME=%MYCAT_HOME% -cp "..\conf;..\lib\*" io.mycat.MycatStartup
pause
