Galera For Mysql

一软件包安装

#集群配置规划
192.168.1.11	node1	CentOS6
192.168.1.12	node2	Redhat6
192.158.1.13	node3	Redhat6

#清理Mysql环境

for i in `rpm -qa |grep -i mysql`; do
rpm -e --allmatches --nodeps ${i}
done
#安装依赖包
yum -y install libaio1 libdbi-perl libdbd-mysql-perl rsync openssl


#安装psmisc 
yum -y install psmisc


#安装mysql client
rpm -ivh MySQL-client-5.6.15-1.linux_glibc2.5.x86_64.rpm


#安装MySQL-shared-compat及除过server以外的包安装上

#devel:开发mysql客户端所需要的库；

#share：开发mysql客户端所需要的链接库

#shared-compat:兼容版本的开发mysql客户端所需要的链接库

#test：测试库
rpm -ivh MySQL-shared-compat-5.6.15-1.linux_glibc2.5.x86_64.rpm \
MySQL-devel-5.6.15-1.linux_glibc2.5.x86_64.rpm \
MySQL-shared-5.6.15-1.linux_glibc2.5.x86_64.rpm \
MySQL-test-5.6.15-1.linux_glibc2.5.x86_64.rpm


#安装包含wsrep-API的Mysql Server包
rpm -ivh MySQL-server-5.6.16_wsrep_25.5-1.rhel6.x86_64.rpm


#安装Galera Replicator包
rpm -ivh galera-25.3.5-1.rhel6.x86_64.rpm

二集群环境配置

#服务器配置

##iptables

##SElinux

#省略

#数据库配置

#创建数据库

mkdir -p /opt/dbdata/mysql_3307
chown -R mysql:mysql /opt/dbdata/mysql_3307
chmod -R 755 /opt/dbdata/mysql_3307
mysql_install_db --user=mysql --datadir=/opt/dbdata/mysql_3307


##node1 配置my.cnf
