提前yum安装依赖包
yum -y install perl perl-devel libaio* 'perl(Data::Dumper)'
准备好mysql的tar包
1、在/usr/local下解压mysql的安装包，并将解压后的文件改名为mysql，其执行命令
tar zxvf mysql-5.6.16-linux-glibc2.5-x86_64.tar解压
mv mysql-5.6.16-linux-glibc2.5-x86_64 mysql 改名
2、建立mysql用户，并赋予/usr/local/mysql目录的权限
useradd mysql 建用户
chown mysql:mysql -R mysql 赋权
3、建立数据目录，并把目录赋权给mysql用户
mkdir -p /data/mysql建数据目录
chown mysql:mysql -R /data赋权
查看赋权是否成功，可在其目录上以及ll查看所属用户及权限
4、配置文件
在/etc目录下新建my.cnf文件，并编辑配置文件
vim /etc/my.cnf创建并编辑配置文件，写入以下内容
注意：以下配置中适合主库，若要对从库使用，需要注释配置中的事件event_scheduler = 1

5、初始化数据库
/usr/local/mysql/scripts/mysql_install_db --defaults-file=/etc/my.cnf --basedir=/usr/local/mysql --datadir=/data/mysql/ --user=mysql

初始化报错：[root@localhostdata]#/usr/local/mysql/scripts/mysql_install_db--defaults-file=/etc/my.cnf--datadir=/data/mysql/--basedir=/usr/local/mysql--user=mysqlCan'tlocateData/Dumper.pmin@INC(@INCcontains:/usr/local/lib64/perl5/usr/local/share/perl5/usr/lib64/perl5/vendor_perl/usr/share/perl5/vendor_perl/usr/lib64/perl5/usr/share/perl5.)at/usr/local/mysql/scripts/mysql_install_dbline42.BEGINfailed--compilationabortedat/usr/local/mysql/scripts/mysql_install_dbline42.解决：yuminstall'perl(Data::Dumper)'

6、启动数据库
/bin/mysqld_safe --defaults-file=/etc/my.cnf &
或者通过cp数据库启动脚本
cp /usr/local/mysql/support-files/mysql.server/etc/init.d/mysqld
chmod +x /etc/init.d/mysqld
启动： /etc/init.d/mysqld start
关闭： /etc/init.d/mysqld stop
7、加入到开机自启
chkconfig --add mysqld
chkconfig --list mysqld 查看mysql的开启等级
chkconfig --level 0 mysqld on

8、注意配置环境变量
9、从库配置，请加上如下参数，记得注意主从的server_id不能相同

log_slave_updates=1relay-log=/data/mysql/relay-log-binrelay-log-index=/data/mysql/slave-relay-bin.indexmax_relay_log_size=300M#关闭自动删除relay-logrelay_log_purge=0
