時間：2022-09-11來源：www.farandoo.com作者：電腦系統城

一、下載

下載地址：https://dev.mysql.com/downloads/mysql/

二、解壓

1	`tar` `xvf mysql-5.7.39-1.el7.x86_64.rpm-bundle.tar`

三、卸載已安裝包

1 2	`rpm -qa\|grep` `mariadb` `mariadb-libs-5.5.68-1.el7.x86_64`

1	`rpm -e --nodeps mariadb-libs-5.5.68-1.el7.x86_64`

四、按順序安裝rpm包

1
2
3
4
5
6 rpm -ivh mysql-community-common-5.7.39-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.39-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.39-1.el7.x86_64.rpm
// 如果安裝 mysql-community-server-5.7.39-1.el7 報 libaio.so.1 依賴錯誤，需先安裝 libaio-0.3.109-13.el7.x86_64.rpm
rpm -ivh libaio-0.3.109-13.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.39-1.el7.x86_64.rpm

安裝 server 還可能報錯：

1
2
3
4 rpm -ivh mysql-community-server-5.7.39-1.el7.x86_64.rpm
warning: mysql-community-server-5.7.39-1.el7.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3a79bd29: NOKEY
error: Failed dependencies:
net-tools is needed by mysql-community-server-5.7.39-1.el7.x86_64

執行以下命令安裝 net-tools 解決：

1	`yum` `install` `net-tools -y`

五、啟動

1	`systemctl start mysqld`

六、找到初始密碼

1	`cat` `/var/log/mysqld.log \|` `grep` `'password is generated'`

七、修改密碼并授權

1
2
3 alter user 'root'@'localhost' identified by 'xxxxxx';
grant all privileges on *.* to 'root'@'%' identified by 'xxxxxx' with grant option;
flush privileges;

八、開啟防火墻，允許外網訪問

1
2
3 firewall-cmd --zone=public --add-port=3306/tcp --permanent
firewall-cmd --reload
firewall-cmd --list-ports
