拼搏现实的明天。 2022-06-01 12:44 303阅读 0赞

1、 **Windows环境下下载mysql安装包，选择RPM Bundle 下载，这是多个rpm文件的压缩包**；

网址： [https://dev.mysql.com/downloads/mysql/][https_dev.mysql.com_downloads_mysql]

2、 **用xshell链接虚拟机的redhat7，然后再xshell中输入rz选择我们下载的安装包mysql-5.7.21-1.el7.x86\_64.rpm-bundle.tar，导入的虚拟机中，并解压；**

3、 **检查系统是否已经安装了mysql**

rpm -aq | grep mysql，如果有旧版本就需要像下面卸载mariadb一样卸载掉。Mariadb是rhel系统已经安装好了的，需要卸载掉，Mariadb也被视为开源数据库MySQL的替代品，安装MySQL时可能有冲突，查看Mariadb，代码 rpm  -qa | grep mariadb,通过rpm -e命令将mariadb卸载掉

例如：  rpm  -e mariadb-libs-5.5.52-1.el7.x86\_64 --nodeps

rpm -e mariadb-server-5.5.52-1.el7.x86\_64  --nodeps

rpm  -e  mariadb-5.5.52-1.el7.x86\_64  --nodeps

4、 **root用户下，在目录/usr/local下创建mysql目录，然后将我们需要安装的文件复制到该目录；**

\[root@bogon mysql\_rpm\]\# cp mysql-community-client-5.7.21-1.el7.x86\_64.rpm /usr/local/mysql/  
\[root@bogon mysql\_rpm\]\# cp mysql-community-common-5.7.21-1.el7.x86\_64.rpm /usr/local/mysql  
\[root@bogon mysql\_rpm\]\# cp mysql-community-libs-5.7.21-1.el7.x86\_64.rpm /usr/local/mysql/  
\[root@bogon mysql\_rpm\]\# cp mysql-community-server-5.7.21-1.el7.x86\_64.rpm /usr/local/mysql/  
\[root@bogon mysql\_rpm\]\# cp mysql-community-devel-5.7.21-1.el7.x86\_64.rpm /usr/local/mysql  
5、 **按顺序对rpm文件进行安装**

\[root@bogon mysql\]\#  rpm -ivh mysql-community-common-5.7.21-1.el7.x86\_64.rpm  
警告：mysql-community-common-5.7.21-1.el7.x86\_64.rpm: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY

6、 **打开mysql的服务**

\[root@bogon mysql\]\#  service mysqld start  
Redirecting to /bin/systemctl start mysqld.service

7、 **查看MySQL服务状态**

\[root@bogon mysql\]\#  service mysqld status  
Redirecting to /bin/systemctl status mysqld.service  
● mysqld.service - MySQL Server  
Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled)

1月 27 20:45:49 bogon systemd\[1\]: Started MySQL Server.

8、 **MySQL安装成功后，会生成一个临时密码，我们第一次登陆需要输入这个密码，所以查看该临时密码，如下，cbZUwQ&Ry3Ut即为临时密码**；

\[root@bogon mysql\_rpm\]\#  grep password /var/log/mysqld.log  
2018-01-28T04:45:43.117298Z 1 \[Note\] A temporary password is generated for root@localhost: cbZUwQ&Ry3Ut

9、 **登陆MySQL**

登录代码 mysql -u root -p  回车就让你输入密码，输入密码的时候，粘贴上面的cbZUwQ&Ry3Ut即可；

10、**修改密码**

mysql>  set password for 'root'@'localhost'='Aoeiuv\_123'；  
Query OK, 0 rows affected (0.00 sec)

11、**授权用户momo登陆**

mysql>  grant all privileges on \*.\* to momo@'%' identified by 'Aoeiuv\_123';  
Query OK, 0 rows affected, 1 warning (0.01 sec)

12、**momo用户登陆MySQL**

\[momo@bogon mysql\_rpm\]$  mysql -u momo -p  
Enter password:
