mysql我一般都用percona版的，如果你配置比较低的话，干脆安装mysql5.1得了,一样能用啊。

yum install mysql  mysql-devel  mysql-server -y
/etc/init.d/mysqld start
chkconfig mysqld on

如果你非要跟我折腾,哦对，网络还可能会很慢，你可以自己做一个PERCONA的源

#创建相关目录
mkdir -p /data/{mytmpbkdir,mysql,backup} && cd /root/software/ && mkdir -p /data/logs/mysql/
#下载percona源
wget -c http://scripts.showshowbaby.com/lnmp/soft/{percona-release-0.0-1.x86_64.rpm,epel-release-6-8.noarch_x64.rpm}
#下载脚本，配置
wget -c http://scripts.showshowbaby.com/lnmp/sh/{update_mysql_pd.sh,mysql_slow_cut.sh,innobackupex.sh}
wget -c http://scripts.showshowbaby.com/lnmp/conf/my56.cnf
test -f /etc/my.cnf && \mv /etc/my.cnf /etc/my.cnf.bak
\mv /root/software/my56.cnf /etc/my.cnf
rpm -Uvh /root/software/epel-release-6-8.noarch_x64.rpm
yum install percona-release-0.0-1.x86_64.rpm -y
yum install Percona-Server-server-56.x86_64 Percona-Server-client-56.x86_64 Percona-Server-devel-56.x86_64 Percona-Server-shared-56.x86_64 percona-xtrabackup  percona-toolkit -y
#设置mysql的root密码
cat /dev/urandom | tr -dc A-Za-z0-9_ | head -c 16 > /etc/sqlpass
## slow log && backup scripts
mv /root/software/mysql_slow_cut.sh /root/sh/  && mv /root/software/innobackupex.sh /root/sh/ && chmod +x /root/sh/{mysql_slow_cut.sh,innobackupex.sh}
[ -z "`grep mysql_slow_cut /etc/crontab`" ] && echo "00 00 * * * root /bin/sh /root/sh/mysql_slow_cut.sh >/dev/null 2>&1" >> /etc/crontab
[ -z "`grep innobackupex /etc/crontab`" ] && echo "00 05 * * * root /bin/sh /root/sh/innobackupex.sh >/dev/null 2>&1" >> /etc/crontab
#edit my.cnf
随便加个server-id,或者直接启动MYSQL吧
#启动 /etc/init.d/mysql start
#修改ROOT密码sh /root/software/update_mysql_pd.sh"
#其他就是my.cnf参数自己修改了。
