CentOS 7.6 安装 Mysql 5.7
一、查看CentOS版本
Mysql的版本必须要和CentOS的版本对应！查看CentOS版本的指令如下：
cat /etc/redhat-release
二、下载yum源包
wget http://repo.mysql.com/mysql57-community-release-el7.rpm
三、安装rpm包
sudo rpm -Uvh mysql57-community-release-el7.rpm
四、安装Mysql服务
[root@lanxinmeichen0613 mysql]# sudo yum install mysql-community-server Loaded plugins: fastestmirror, versionlock Determining fastest mirrors base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 mysql-connectors-community | 2.6 kB 00:00:00 mysql-tools-community | 2.6 kB 00:00:00 mysql57-community | 2.6 kB 00:00:00 updates | 2.9 kB 00:00:00 (1/7): base/7/x86_64/group_gz | 153 kB 00:00:00 (2/7): extras/7/x86_64/primary_db | 253 kB 00:00:00 (3/7): mysql-tools-community/x86_64/primary_db | 98 kB 00:00:00 (4/7): mysql-connectors-community/x86_64/primary_db | 114 kB 00:00:00 (5/7): base/7/x86_64/primary_db | 6.1 MB 00:00:00 (6/7): updates/7/x86_64/primary_db | 27 MB 00:00:00 (7/7): mysql57-community/x86_64/primary_db | 361 kB 00:00:00 Resolving Dependencies --> Running transaction check ---> Package mysql-community-server.x86_64 0:5.7.44-1.el7 will be installed --> Processing Dependency: mysql-community-common(x86-64) = 5.7.44-1.el7 for package: mysql-community-server-5.7.44-1.el7.x86_64 --> Processing Dependency: mysql-community-client(x86-64) >= 5.7.9 for package: mysql-community-server-5.7.44-1.el7.x86_64 --> Running transaction check ---> Package mysql-community-client.x86_64 0:5.7.44-1.el7 will be installed --> Processing Dependency: mysql-community-libs(x86-64) >= 5.7.9 for package: mysql-community-client-5.7.44-1.el7.x86_64 ---> Package mysql-community-common.x86_64 0:5.7.44-1.el7 will be installed --> Running transaction check ---> Package mysql-community-libs.x86_64 0:5.7.44-1.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================== Installing: mysql-community-server x86_64 5.7.44-1.el7 mysql57-community 184 M Installing for dependencies: mysql-community-client x86_64 5.7.44-1.el7 mysql57-community 31 M mysql-community-common x86_64 5.7.44-1.el7 mysql57-community 313 k mysql-community-libs x86_64 5.7.44-1.el7 mysql57-community 3.0 M Transaction Summary ==================================================================================================================================== Install 1 Package (+3 Dependent packages) Total download size: 219 M Installed size: 930 M Is this ok [y/d/N]: y Downloading packages: warning: /var/cache/yum/x86_64/7/mysql57-community/packages/mysql-community-common-5.7.44-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY Public key for mysql-community-common-5.7.44-1.el7.x86_64.rpm is not installed (1/4): mysql-community-common-5.7.44-1.el7.x86_64.rpm | 313 kB 00:00:00 (2/4): mysql-community-libs-5.7.44-1.el7.x86_64.rpm | 3.0 MB 00:00:00 (3/4): mysql-community-client-5.7.44-1.el7.x86_64.rpm | 31 MB 00:00:04 (4/4): mysql-community-server-5.7.44-1.el7.x86_64.rpm | 184 MB 00:00:18 ------------------------------------------------------------------------------------------------------------------------------------ Total 11 MB/s | 219 MB 00:00:19 Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql Importing GPG key 0x5072E1F5: Userid : "MySQL Release Engineering <mysql-build@oss.oracle.com>" Fingerprint: a4a9 4068 76fc bd3c 4567 70c8 8c71 8d3b 5072 e1f5 Package : mysql57-community-release-el7-11.noarch (installed) From : /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql Is this ok [y/N]: y Public key for mysql-community-server-5.7.44-1.el7.x86_64.rpm is not installed Failing package is: mysql-community-server-5.7.44-1.el7.x86_64 GPG Keys are configured as: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
五、处理一下报错
[root@lanxinmeichen0613 mysql]# sudo rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
六、继续安装Mysql服务
[root@lanxinmeichen0613 mysql]# sudo yum install -y mysql-community-server Loaded plugins: fastestmirror, versionlock Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package mysql-community-server.x86_64 0:5.7.44-1.el7 will be installed --> Processing Dependency: mysql-community-common(x86-64) = 5.7.44-1.el7 for package: mysql-community-server-5.7.44-1.el7.x86_64 --> Processing Dependency: mysql-community-client(x86-64) >= 5.7.9 for package: mysql-community-server-5.7.44-1.el7.x86_64 --> Running transaction check ---> Package mysql-community-client.x86_64 0:5.7.44-1.el7 will be installed --> Processing Dependency: mysql-community-libs(x86-64) >= 5.7.9 for package: mysql-community-client-5.7.44-1.el7.x86_64 ---> Package mysql-community-common.x86_64 0:5.7.44-1.el7 will be installed --> Running transaction check ---> Package mysql-community-libs.x86_64 0:5.7.44-1.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================== Installing: mysql-community-server x86_64 5.7.44-1.el7 mysql57-community 184 M Installing for dependencies: mysql-community-client x86_64 5.7.44-1.el7 mysql57-community 31 M mysql-community-common x86_64 5.7.44-1.el7 mysql57-community 313 k mysql-community-libs x86_64 5.7.44-1.el7 mysql57-community 3.0 M Transaction Summary ==================================================================================================================================== Install 1 Package (+3 Dependent packages) Total size: 219 M Installed size: 930 M Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Warning: RPMDB altered outside of yum.

七、启动Mysql服务
[root@lanxinmeichen0613 mysql]# systemctl start mysqld.service
八、获取临时密码
[root@lanxinmeichen0613 mysql]# sudo grep 'temporary password' /var/log/mysqld.log 2024-06-14T09:00:04.412228Z 1 [Note] A temporary password is generated for root@localhost: _izgQQt_7/OG
九、修改密码
ALTER USER 'root'@'localhost' IDENTIFIED BY 'f21des';
十、修改远程
mysql> CREATE USER 'root'@'%' IDENTIFIED BY '21des'; Query OK, 0 rows affected (0.00 sec) mysql> GRANT ALL ON *.* TO 'root'@'%'; Query OK, 0 rows affected (0.00 sec) mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)
