1、去官网下载MySQL,https://dev.mysql.com/downloads/mysql/5.6.html#downloads
选择redhat6 64bit
下载rpm bundle
2、将文件拷贝到centos,解压 tar -xvf MySQL-5.6.39-1.el6.x86_64.rpm-bundle.tar
3、检查是否已安装mysql,rpm -qa|grep mysql ,如果有,运行 rpm -e 卸载
4、安装mysql
rpm -ivh MySQL-client-5.6.39-1.el6.x86_64.rpm
rpm -ivh MySQL-devel-5.6.39-1.el6.x86_64.rpm
rpm -ivh MySQL-server-5.6.39-1.el6.x86_64.rpm
安装MySQL-server-5.6.39-1.el6.x86_64.rpm的时候可能会报错,缺少包
这都是因为缺少依赖的相关包造成的,解决办法是通过yum直接安装这些依赖包。 yum -y install libaio
yum -y install numactl
5、将配置文件拷贝到/etc目录下,cp /usr/share/mysql/my-default.cnf /etc/my.cnf
修改配置文件 vi /etc/my.cnf 在[mysqld]下面加上
skip-grant-tables
否则登录时会报 错:
[root@localhost ~]# mysql -u root -p
Enter password:
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
6、启动mysql service mysql start
7、登录mysql,这一步不需要输密码 直接输mysql 即可,修改root密码
mysql> update mysql.user set authentication_string=password('root') where user='root';
Query OK, 4 rows affected (0.00 sec)
Rows matched: 4 Changed: 4 Warnings: 0
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> exit
Bye
vi /etc/my.cnf 将skip-grant-tables注释掉
然后重启mysql
service mysql restart
8、登录mysql
mysql -uroot -p
