1、mysql下载
下载地址:https://dev.mysql.com/downloads/mysql/5.6.html
下载以下安装包:MySQL-client-5.6.33-1.el6.x86_64.rpm
MySQL-devel-5.6.33-1.el6.x86_64.rpm
MySQL-server-5.6.33-1.el6.x86_64.rpm
2、查看是否已经安装了mysql,有则移除
rpm -qa|grep -i mysql
mysql-libs-5.1.66-2.el6_3.x86_64
yum -y remove mysql-libs*
3、安装mysql5.6
rpm -ivh MySQL-client-5.6.33-1.el6.x86_64.rpm
rpm -ivh MySQL-devel-5.6.33-1.el6.x86_64.rpm
rpm -ivh MySQL-server-5.6.33-1.el6.x86_64.rpm
cp /usr/share/mysql/my-default.cnf /etc/my.cn
4、初始化MySQL及设置密码
/usr/bin/mysql_install_db
service mysql start
cat /root/.mysql_secret
mysql -uroot -p初始密码
set PASSWORD=PASSWORD('123456');
exit
5、开启远程访问
mysql -uroot -p123456
use mysql;
update user set password=password('123456') where user='root';
update user set host='%' where user='root' and host='localhost';
flush privileges;
exit
6、设置开机自启动
chkconfig mysql on
7、优化my.cnf配置
vim /etc/my.cnf
[mysqld]
port = 3306
default-storage-engine = InnoDB
lower_case_table_names = 1
max-connections=3000
character_set_server=utf8
[mysql]
default-character-set=utf8
