1、安装mysql
查看原本mysql相关包
# rpm -qa|grep mysql
# ps -ef | grep mysql
# service mysqld stop
# rpm -e mysql-libs --nodeps
# yum -y remove mysql mysql-*
安装common rpm
安装lib rpm
安装client rpm
安装serer rpm
安装devel rpm
2、启动,第一遍启动不成功就在启动几遍，三遍不成功查看启动日志
service mysqld start
3、查看初次启动日志
vim /var/log/mysqld.log
查看初始密码
/password
A temporary password is generated for root@localhost: WidesCvNt5)S
4、修改初始密码
mysql -u root -p
输入初始化密码
mysql> set password for 'root'@'localhost' = password('root@1234');
5、查看并设置开机自启动
chkconfig --list | grep mysqld
chkconfig mysqld on
6、修改字符集为UTF-8
vim /etc/my.cnf
在[mysqld]部份添加:
character-set-server=utf8
在文件末尾新增[client]段,并在[client]段添加:
default-character-set=utf8
7、修改好之后重启mysqld服务
service mysqld restart
查看修改结果
mysql> show variables like "%character%";
8、远程授权
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'idss@1234';
FLUSH PRIVILEGES;
