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;
