1把105的/usr/local/mysql拷过去

2. 把105的/etc/my.cnf拷过去

3. mkdir /data/mysql/{data,tmp,binlog,log}-p

4. 初始化

rpm -qa mysql

yum remove mysql-5.1.73-8.el6_8.x86_64

/etc/my.cnf /etc/my.cnf.bak 

yum install libaio*

useradd mysql

mkdir /data/mysql/{data,tmp,binlog,log} -p

chown -R mysql.mysql /data/mysql

tar xf/tmp/mysql-5.6.20-linux-glibc2.5-x86_64.tar.gz -C /usr/local/

cd /usr/local/

mv mysql-5.6.20-linux-glibc2.5-x86_64 mysql

chown -R mysql.mysql /usr/local/mysql

cd /usr/local/mysql/scripts

./mysql_install_db --datadir=/data/mysql/data--basedir=/usr/local/mysql --user=mysql --explicit_defaults_for_timestamp

echo "/usr/local/mysql/lib" >/etc/ld.so.conf.d/mysql.conf && ldconfig -v

ln -s /usr/local/mysql/include /usr/include/mysql

cp /usr/local/mysql/support-files/mysql.server/etc/init.d/mysqld

chkconfig mysqld on

echo "exportPATH=$PATH:/usr/local/mysql/bin" > /etc/profile.d/mysql.sh

source /etc/profile

/etc/init.d/mysqld restart

ps -ef|grep mysql

mysqladmin -uroot password 'Z2323445' -S  /data/mysql/mysqld.sock

mysql -uroot -p -S /data/mysql/mysqld.sock

mysql初步优化：

drop database test;drop user root@'::1';drop user''@'localhost';drop user ''@'localhost.localdomain';drop user 'root'@'localhost.localdomain';select user,host from mysql.user; flush privileges;

以及添加天兔lepus监控mysql

grant insert,update,delete,create,select,super,process,reload,showdatabases,replication client on *.* to'lepus_monitor'@'221.203.45.78' identified by 'LepUs@zy@MoniTOR'; flush privileges;

mysql5.6.20 my.cnf配置文件

服务器环境为dellr710服务器，内存:60G,cpu是超线程
