实验系统:CentOS 6.6_x86_64
实验前提:防火墙和selinux都关闭
实验说明:本实验共有5台主机,IP分配如拓扑
实验软件:mariadb-10.0.20 MySQL-mmm-2.2.1 mysql-mmm-monitor-2.2.1 mysql-mmm-agent-2.2.1

------------------------------------------分割线------------------------------------------
实验拓扑:
mysql proxy、MySQL-MMM实现读写分离高可用性
将MySQL-MMM Master从REPLICATION_FAIL状态恢复
一、准备工作
1.根据下表,将各主机名进行修改:
2.修改hosts文件,添加如下内容:
vim /etc/hosts
------------------------------------------->
192.168.19.21 mon
192.168.19.66 db1
192.168.19.74 db2
192.168.19.76 db3
192.168.19.79 db4
3.规划虚拟ip,列表如下:
二、安装mariadb并配置
1.在db1-4上安装:
tar xf mariadb-10.0.20-linux-x86_64.tar.gz -C /usr/local/
cd /usr/local/
ln -sv mariadb-10.0.20-linux-x86_64 mysql
useradd -r mysql
mkdir -pv /mydata/data
chown -R mysql.mysql /mydata/data/
cd mysql/
chown -R root.mysql .
scripts/mysql_install_db --user=mysql --datadir=/mydata/data/
cp support-files/my-large.cnf /etc/my.cnf
cp support-files/mysql.server /etc/init.d/mysqld
chkconfig --add mysqld
chkconfig mysqld on
2.编辑配置文件: db1:
vim /etc/my.cnf
--------------------------------------------->
[mysqld]
server-id = 1
datadir = /mydata/data
log-bin = /mydata/data/mysql1-bin
binlog_format = ROW
relay_log = /mydata/data/relay-log
auto-increment-increment = 2
auto-increment-offset = 1
sync_binlog = 1
sync_master_info = 1
sync_relay_log = 1
sync_relay_log_info = 1
max_binlog_size = 100M
log_slave_updates = 1
<---------------------------------------------
service mysqld start
db2:
vim /etc/my.cnf
--------------------------------------------->
[mysqld]
server-id = 2
datadir = /mydata/data
log-bin = /mydata/data/mysql2-bin
binlog_format = ROW
relay_log = /mydata/data/relay-log
auto-increment-increment = 2
auto-increment-offset = 2
sync_binlog = 1
sync_master_info = 1
sync_relay_log = 1
sync_relay_log_info = 1
max_binlog_size = 100M
log_slave_updates = 1
<---------------------------------------------
service mysqld start
db3:
vim /etc/my.cnf
--------------------------------------------->
[mysqld]
server-id = 3
datadir = /mydata/data
log-bin = /mydata/data/mysql3-bin
binlog_format = ROW
relay_log = /mydata/data/relay-log
sync_binlog = 1
sync_master_info = 1
sync_relay_log = 1
sync_relay_log_info = 1
max_binlog_size = 100M
log_slave_updates = 1
<---------------------------------------------
service mysqld start
db4:
vim /etc/my.cnf
--------------------------------------------->
[mysqld]
server-id = 4
datadir = /mydata/data
log-bin = /mydata/data/mysql4-bin
binlog_format = ROW
relay_log = /mydata/data/relay-log
sync_binlog = 1
sync_master_info = 1
sync_relay_log = 1
sync_relay_log_info = 1
max_binlog_size = 100M
log_slave_updates = 1
<---------------------------------------------
service mysqld start
这里需要创建三个用户,如下表:
