CentOS7 安裝mysql並解決安裝慢的問題

0、centOS7 mini版安裝及網絡配置

//可從我的網盤保存下載，可用虛擬機安裝

鏈接:https://pan.baidu.com/s/10_AHxN0DtJ75s1oFOaaZ3A  密碼:udsn

//初始用戶名是root，密碼自己安裝前設置 

//安裝網絡查看工具ifconfig 
yum install net-tools 

//本地電腦ssh獲取ip連接

1 、下載並安裝MySQL官方的 Yum Repository

wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql57-community-release-el7-10.noarch.rpm

yum -y install mysql-community-server

2、發現安裝太慢

//1、去國內鏡像站下載對應版本的client和server rpm包
推薦：http://uni.mirrors.163.com/mysql/Downloads/

//2、cd到目錄
/var/cache/yum/x86_64/7/mysql57-community/packages/

//3、把下載好的rpm文件上傳到此目錄
mysql-community-client-5.7.29-1.el7.x86_64.rpm
mysql-community-server-5.7.29-1.el7.x86_64.rpm

//4、再次執行安裝命令
yum -y install mysql-community-server

3、 MySQL數據庫設置

//開啟MySQL
systemctl start  mysqld.service

//獲取臨時密碼
grep "password" /var/log/mysqld.log

//進入數據庫
mysql -uroot -p

//修改密碼驗證規則
mysql> set global validate_password_policy=0;
mysql> set global validate_password_length=1;

//設置簡單密碼

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';

4、 卸載mysql安裝更新

yum -y remove mysql57-community-release-el7-10.noarch

5、 徹底解決python mysqlclient 安裝失敗的問題

cd /etc/yum.repos.d/

rpm -ivh http://repo.mysql.com/mysql57-community-release-el7-8.noarch.rpm

sudo yum install mysql-devel

sudo yum install python3-devel

pip install mysqlclient

6、 解決pycharm與遠程服務器庫不一致的問題

保證遠程interpreter的項目映射地址和tools->deployment里的map映射地址一致

如果還不更新，點擊interpreter右上角reset刷新即可
