Linux系统环境：CentOS 6.5
master1：192.168.100.204
master2：192.168.100.205
mysql版本：mysql-5.6.19
注：mysql的5.5以下的版本和5.5以上的版本配置方法不一样
以下两个节点安装
1：防火墙打开相应端口
# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
# /etc/rc.d/init.d/iptables save
2：安装相关依赖包
# yum -y install gcc gcc-c++ ncurses ncurses-devel openssl openssl-devel cmake perl lsof bison
3：删除自带的mysql
# rpm -qa|grep mysql
# rpm -e --allmatches --nodeps mysql-libs-5.1.71-1.el6.x86_64
4：创建相关目录
# mkdir /linuxidc/soft
# mkdir -p /linuxidc/mysql/data/
5：创建mysql用户
# /usr/sbin/groupadd mysql
# /usr/sbin/useradd -s /sbin/nologin -M -g mysql mysql
# chown -R mysql:mysql /linuxidc/mysql/
6：安装mysql
# cd /linuxidc/soft
# tar -zxvf mysql-5.6.19.tar.gz
# cd mysql-5.6.19
# cmake -DCMAKE_INSTALL_PREFIX=/linuxidc/server/mysql -DMYSQL_DATADIR=/linuxidc/mysql/data -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DSYSCONFDIR=/etc/ -DWITH_SSL=yes -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci -DWITH_READLINE=on
# make && make install
7：修改相关目录权限并创建软连接
# chmod +w /linuxidc/server/mysql
# chown -R mysql:mysql /linuxidc/server/mysql/
# ln -s /linuxidc/server/mysql/lib/lib* /usr/lib/
# ln -s /linuxidc/server/mysql/bin/mysql /usr/bin
8：修改配置文件
# cp /linuxidc/server/mysql/support-files/my-default.cnf /etc/my.cnf
# vi /etc/my.cnf
[mysqld]
character-set-server = utf8
default-storage-engine = MyISAM
basedir = /linuxidc/server/mysql
datadir = /linuxidc/mysql/data
log-error = /linuxidc/mysql/mysql_error.log
pid-file = /linuxidc/mysql/mysql.pid
max_allowed_packet = 32M
explicit_defaults_for_timestamp = true
9：安装mysql数据库
# /linuxidc/server/mysql/scripts/mysql_install_db --basedir=/linuxidc/server/mysql --datadir=/linuxidc/mysql/data --user=mysql
10：设置mysql开机自动启动服务
# cp /linuxidc/server/mysql/support-files/mysql.server /etc/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --level 345 mysqld on
11：修改mysqld文件并启动mysql
# vi /etc/init.d/mysqld
#修改mysqld文件中的下面两项
basedir=/linuxidc/server/mysql
datadir=/linuxidc/mysql/data
# service mysqld start
12：创建需同步的数据库
# mysql -uroot -p
mysql> create database linuxidc;
mysql> GRANT ALL PRIVILEGES ON linuxidc.* TO doiido@"%" IDENTIFIED BY 'linuxidc123';
mysql> exit
--------------------以下在服务器master1上操作
修改配置文件
# vi /etc/my.cnf
[mysqld]
#默认是1，master和slave不能相同即可
server-id=1
log-bin=bin.log
port=3306
binlog-do-db =linuxidc
#要复制的数据库
replicate-do-db =linuxidc
重启mysql
# service mysqld restart
建立用于同步的账户
# mysql -uroot -p
mysql> grant replication slave on *.* to 'dodo'@'192.168.100.205' identified by 'jjjjjj';
查看File对应值，并记录下来
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| bin.000001 | 120 | linuxidc | | |
+------------------+----------+--------------+------------------+-------------------+
mysql> exit
--------------------以下在服务器master2上操作
2.修改slave上的配置文件my.cnf
# vi /etc/my.cnf
[mysqld]
server-id=2
port=3306
log-bin=bin.log
binlog-do-db =linuxidc
replicate-do-db =linuxidc
重启mysql
# service mysqld restart
在从服务器上建立相应的数据库
# mysql -uroot -p
将192.168.100.204设置为自己的主服务器
mysql> CHANGE MASTER TO
MASTER_HOST='192.168.100.204',MASTER_PORT=3306,
MASTER_USER='dodo',
MASTER_PASSWORD='jjjjjj',
MASTER_LOG_FILE='bin.000001',
MASTER_LOG_POS=120;
启动从服务器复制功能
mysql> start slave;
mysql> show slave status\G;
...................
Slave_IO_Running: Yes
Slave_SQL_Running: Yes
