由于項(xiàng)目需要，需要在rh7.4上安裝mysql版本，之前6.8的環(huán)境直接掛載iso yum源安裝，rh7以上的版本只有手工安裝了

1.安裝前準(zhǔn)備

到mysql官網(wǎng)下載相應(yīng)的rpm包

下載地址：https://dev.mysql.com/downloads/mysql/5.7.html#downloads

選擇自己需要的版本

官網(wǎng)下載速度較慢，有需要的可以到我的共享下載

2.通過(guò)scp上傳至需要安裝的服務(wù)器并解壓

tar -xvf mysql-5.7.26-1.el7.x86_64.rpm-bundle.tar -C /opt/

解壓后文件

mysql-community-embedded-devel-5.7.26-1.el7.x86_64.rpm

mysql-community-libs-5.7.26-1.el7.x86_64.rpm

mysql-community-embedded-5.7.26-1.el7.x86_64.rpm

mysql-community-test-5.7.26-1.el7.x86_64.rpm

mysql-community-embedded-compat-5.7.26-1.el7.x86_64.rpm

mysql-community-common-5.7.26-1.el7.x86_64.rpm

mysql-community-devel-5.7.26-1.el7.x86_64.rpm

mysql-community-client-5.7.26-1.el7.x86_64.rpm

mysql-community-server-5.7.26-1.el7.x86_64.rpm

mysql-community-libs-compat-5.7.26-1.el7.x86_64.rpm

3.考慮到安裝包依賴(lài)關(guān)系，通過(guò)rpm按照順序安裝

rpm -ivh mysql-community-common-5.7.26-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-5.7.26-1.el7.x86_64.rpm

rpm -ivh mysql-community-client-5.7.26-1.el7.x86_64.rpm

rpm -ivh mysql-community-libs-compat-5.7.26-1.el7.x86_64.rpm

rpm -ivh mysql-community-server-5.7.26-1.el7.x86_64.rpm

4.啟動(dòng)并查看mysql狀態(tài)

systemctl start mysqld.service

systemctl status mysqld.service

5.通過(guò)/var/log/mysqld.log查找mysql密碼并登陸

[root@hadoop-2 log]# grep "pass"? mysqld.log

2019-06-19T00:59:58.620256Z 1 [Note] A temporary password is generated for root@localhost: Ve9vP<vp3CiU

2019-06-19T01:00:20.364725Z 2 [Note] Access denied for user 'root'@'localhost' (using password: NO)

[root@hadoop-2 opt]# mysql -uroot -p

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'Abcde2008!';
