CentOS中mysql cluster安装部署教程

[root@MGM ]#rpm -qa|grep mysql （查询系统中存在的mysql)

[root@MGM ]#rpm -e –nodeps mysql-libs-5.1.71-1.el6.i686 (根据自己查出来的mysql版本)

[root@MGM ]#groupadd mysql

[root@MGM ]#useradd mysql -g mysql

[root@MGM ]#cd /usr/local (软件包在此目录下，根据自己存放位置进入)

[root@MGM local]#tar -xvfmysql-cluster-gpl-7.2.25-linux2.6-i686.tar.gz

[root@MGM local]#mkdir /usr/local/mysql (创建mysql目录）

[root@MGM local]#mvmysql-cluster-gpl-7.2.25-linux2.6-i686/ mysql

[root@MGM local]#chown -R mysql:mysql mysql/

[root@MGM local]#cd mysql

[root@MGM mysql]#scripts/mysql_install_db –user=mysql (管理及数据节点执行这条命令)

#scripts/mysql_install_db –user=mysql –datadir=/var/mysql/data （sql节点执行这条命令）

[root@MGM mysql]#mkdir /var/lib/mysql-cluster

[root@MGM ]#mkdir /var/mysql

[root@MGM ]#mkdir /var/mysql/data

[root@MGM ]#mkdit /var/mysql/log

[root@MGM mysql]#vi /var/lib/mysql-cluster/config.ini (添加以下内容)
