1.检测系统是否已经安装过mysql或其依赖,若已装过要先将其删除,否则第4步使用yum安装时会报错:
1 # yum list installed | grep mysql 2 mysql-libs.i686 5.1.71-1.el6 @anaconda-CentOS-201311271240.i386/6.5 3 # yum -y remove mysql-libs.i686
2.从mysql的官网下载mysql57-community-release-el6-5.noarch.rpm(注意这里的el6-5即适配RHEL6.5的版本,如果下载了其它版本后面的安装过程中可能会报错):
wget dev.mysql.com/get/mysql-community-release-el6-5.noarch.rpm
3.安装第一步下载的rpm文件:
yum install mysql-community-release-el6-5.noarch.rpm
安装成功后,我们可以看到/etc/yum.repos.d/目录下增加了以下两个文件
1 # ls /etc/yum.repos.d 2 mysql-community-source.repo 3 mysql-community.repo
查看mysql57的安装源是否可用,如不可用请自行修改配置文件(/etc/yum.repos.d/mysql-community.repo)使mysql57下面的enable=1
若有mysql其它版本的安装源可用,也请自行修改配置文件使其enable=0
1 # yum repolist enabled | grep mysql 2 mysql-connectors-community MySQL Connectors Community 13 3 mysql-tools-community MySQL Tools Community 18 4 mysql57-community-dmr MySQL 5.7 Community Server Development Milesto 65
4.使用yum安装mysql:
yum install mysql-community-server
5.启动mysql服务:
service mysqld start
查看root密码:
1 # grep "password" /var/log/mysqld.log 2 2016-08-10T15:03:02.210317Z 1 [Note] A temporary password is generated for [email protected]: AYB(&-3Cz-rW
现在必须立刻修改密码,不然会报错:
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
修改密码(如果在此步报错ERROR 1819,请向下翻查看原因及解决方法):
mysql> SET PASSWORD FOR ‘root‘@‘localhost‘ = PASSWORD(‘newpass‘);
6.查看mysqld是否开机自启动,并设置为开机自启动:
1 chkconfig --list | grep mysqld 2 chkconfig mysqld on
7.修改字符集为UTF-8:
vim /etc/my.cnf
在[mysqld]部分添加:
character-set-server=utf8
在文件末尾新增[client]段,并在[client]段添加:
default-character-set=utf8
修改好之后重启mysqld服务:
service mysqld restart
8.登录mysql并修改密码:
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD(‘newpassword‘) where USER=‘root‘;
mysql> FLUSH PRIVILEGES;
mysql> quit
