一，系统环境centos 6.3 ,master a ip:192.168.1.28,master b ip:192.168.1.29。
 
二，安装cmake与mysql
 
1，安装cmake
 
#tar xf cmake-2.8.8.tar.gz 
 
#cd cmake-2.8.8 
 
# ./bootstrap 
 
# gmake && gmake install 
 
2，，安装mysql
 
#useradd -r mysql  -s /sbin/nologin
 
#mkdir -p /data/mysql/{data,binlog,relaylog}
 
#chown mysql:mysql -r /data/mysql
 
# tar xf mysql-5.5.27.tar.gz   
 
#cd mysql-5.5.27
 
#cmake -dcmake_install_prefix=/usr/local/mysql -ddefault_charset=utf8 -ddefault_collation=utf8_general_ci -dextra_charsets=all -dwith_myisam_storage_engine=1 -dwith_innobase_storage_engine=1  -denabled_local_infile=1 -dmysql_datadir=/data/mysql/data  -dwith_debug=0  -dsysconfdir=/etc -dmysql_tcp_port=3306 
 
#会编译不过去，提示需要安装ncurses-devel,yum -y install ncurses-devel
 
#rm -f cmakecache.txe 重新执行./configure
 
# make && make install 
 
#cd /usr/local/mysql
 
#chown -r mysql:mysql *
 
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
 
#chmod +x /etc/init.d/mysqld
 
#chkconfig mysqld on
 
# vim /etc/profile  添加path=$path:/usr/local/mysql/bin
 
# . /etc/profile(或者export path=$path:/usr/local/mysql/bin) 
 
# ln -sv /usr/local/mysql/include/ /usr/include/mysql 
 
# echo '/usr/local/mysql/lib' > /etc/ld.so.conf.d/mysql.conf 加载库文件 
 
# ldconfig -v |grep mysql 
 
# vim /etc/man.config 添加一行manpath /usr/local/mysql/man
 
环境已经基本ok
 
# cd /usr/local/mysql
 
scripts/mysql_install_db --user=mysql --datadir=/data/mysql
 
将主服务器克隆一份，并修改ip与mac地址，保证两台机器能够互相ping通。
