Centos7 安装 Mysql5.7 阿里云安装

可以参照之前第一篇的 Mysql 安装，都是可以的
CentOS7 安装 Mysql

卸载

卸载掉安装的部分 首先执行查看命令，看一下都安转了什么东东：

[root@ppl ~]# rpm -qa|grep -i mysql
mysql57-community-release-el7-10.noarch
mysql-community-client-5.7.24-1.el7.x86_64
mysql-community-libs-5.7.24-1.el7.x86_64
mysql-community-libs-compat-5.7.24-1.el7.x86_64
mysql-community-common-5.7.24-1.el7.x86_64
mysql-community-server-5.7.24-1.el7.x86_64
[root@ppl ~]#

有的话就开始卸载 执行卸载命令：

yum remove mysql-community mysql-community-server mysql-community-libs mysql-communitycommon
yum remove mysql57-community-release-el7-10.noarch

终极检查 再进行一遍检查： rpm -qa |grep -i mysql ，安装部分已完全卸载掉。
清理文件 查看 mysql 文件目录： find / -name mysql .

[root@ppl ~]# rpm -qa|grep -i mysql
[root@ppl ~]# find / -name mysql
/usr/share/mysql
[root@ppl ~]# rm -rf /usr/share/mysql
[root@ppl ~]# find / -name mysql
[root@ppl ~]#

检查 mysql 源是否安装成功

[root@ppl ~]# yum repolist enabled | grep "mysql.*-community.*"

或者安装完成后会将 MySQL 的 Yum 仓库添加到系统的仓库 list 中，可以/etc/yum.repos.d 目录下看到新增的两个文
件(mysql-community.repo 和 mysql-community-source.repo)。

[root@ppl ~]# cd /etc/yum.repos.d

如果出现以下错误

Error downloading packages:

yum clean all
yum makecache
yum update 或者 yum -y update

登录

修改 root 本地登录密码
安装完成后，会生成一个临时的随机密码给 root 账户，保存在/var/log/mysqld.log，可以使用命令查看。

[root@ppl ~]# grep 'temporary password' /var/log/mysqld.log
2018-11-05T04:41:11.945054Z 1 [Note] A temporary password is generated for
root@localhost: rgX(v.oM>3nl
[root@ppl ~]#

启动 MySQL 服务

systemctl start mysqld

查看 MySQL 的启动状态

systemctl status mysqld

结果如下

[root@ppl ~]# systemctl start mysqld
[root@ppl ~]# systemctl status mysqld

登录后要立即修改密码

[root@ppl ~]# mysql -u root -p 或者 mysql -uroot -p
输入初始密码后
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '1qazxsw2A@#';
Query OK, 0 rows affected (0.00 sec)
mysql>

允许 root 远程登录

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1qazxsw2A@#' WITH GRANT
OPTION;
Query OK, 0 rows affected, 1 warning (0.00 sec)
mysql> flush privileges;
