1.删除原有的mariadb,不然mysql装不进去
mariadb-libs-5.5.52-1.el7.x86_64
rpm -qa|grep mariadb
rpm -e --nodeps mariadb-libs
1.在/downloads/mysql/选择为Red Hat Enterprise Linux 7 / Oracle Linux 7 ,把os的版本选择为all。
直接下载mysql-5.7.21-1.el7.x86_64.rpm-bundle.tar,所有的rpm包都在里面
rpm -ivh mysql-community-common-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.21-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.21-1.el7.x86_64.rpm
至此,mysql5.7所有文件安装完毕,接下来就是开启服务测试了。
1.首先关闭mysql服务:
service mysqld stop
2.然后修改配置文件:
vim /etc/f
3.接下来加入一句代码即可空密码登录mysql:
# Disabling symbolic-links is recommended to prevent assorted security risks
skip-grant-tables #添加这句话,这时候登入mysql就不需要密码
symbolic-links=0
4.开启mysql服务:
service mysqld start
5.空密码登录mysql:
mysql -u root -p #输入命令回车进入,出现输入密码提示直接回车
6.设置mysql密码:
mysql> set password for root@localhost = password('123456');
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> flush privileges; #更新权限
Query OK, 0 rows affected (0.00 sec)
mysql> set password for root@localhost = password('123456');
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql>flush privileges; #更新权限
mysql>quit; #退出
service mysqld stop # 停止mysql服务, 恢复mysql配置
vim /etc/f #修改配置文件
# Disabling symbolic-links is recommended to prevent assorted security risks
# skip-grant-tables # 注释掉这句话
symbolic-links=0
service mysqld start # 启动mysql服务
mysql -uroot -p # 输入新密码登录
7.设置mysql开机自启:
systemctl enable mysqld
