centos7.6離線安裝mysql5.7（附下載連接）

 

原本打算直接用原生yum源安裝，可是跨國訪問網絡太慢，只好採用離線安裝的方式，原理就是把所需的rpm下載下來再上傳服務器安裝。

一、rpm文件下載地址：

目錄： http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/

具體文件：

http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-common-5.7.28-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-devel-5.7.28-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-libs-5.7.28-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-connectors-community/el/7/x86_64//mysql-connector-odbc-8.0.18-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-client-5.7.28-1.el7.x86_64.rpm
http://repo.mysql.com/yum/mysql-5.7-community/el/7/x86_64/mysql-community-server-5.7.28-1.el7.x86_64.rpm

 

二、安裝依賴環境

yum -y install numactl

 

三、卸載mariadb

[root@hadoop ~]# rpm -qa|grep mariadb mariadb-libs-5.5.52-1.el7.x86_64 [root@hadoop ~]# rpm -e --nodeps mariadb-libs-5.5.52-1.el7.x86_64 [root@hadoop ~]# rpm -qa|grep mariadb

 

三、安裝原生yum源（非必選）

wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
yum localinstall mysql57-community-release-el7-8.noarch.rpm

 

四、安裝mysql rpm

rpm -ivh mysql-community-common-5.7.28-1.el7.x86_64.rpm rpm -ivh mysql-community-devel-5.7.28-1.el7.x86_64.rpm rpm -ivh mysql-community-libs-compat-5.7.28-1.el7.x86_64.rpm rpm -ivh mysql-community-libs-5.7.28-1.el7.x86_64.rpm rpm -ivh mysql-connector-odbc-8.0.18-1.el7.x86_64.rpm rpm -ivh mysql-community-client-5.7.28-1.el7.x86_64.rpm rpm -ivh mysql-community-server-5.7.28-1.el7.x86_64.rpm

 

五、啓動mysql服務器

service mysqld start

 

六、修改密碼

mysql默認給root帳號配置了臨時密碼，須要手動改爲本身的

查看方式：

cat /var/log/mysqld.log | grep password 2019-12-22T08:14:59.578240Z 1 [Note] A temporary password is generated for root@localhost: !Ml,ThwaB0d_

其中末尾的「!Ml,ThwaB0d_」就是password

登陸mysql：mysql -uroot -p

修改密碼策略（防止不能設置本身想設置的密碼，若是想要設置的密碼複雜度夠，能夠跳過）：

set global validate_password_policy=0; set global validate_password_length=1;

修改密碼：

alter user 'root'@'localhost' identified by '1234'; flush privileges;

 

七、容許遠程登陸

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '1234' WITH GRANT OPTION; FLUSH PRIVILEGES;
