第一部分wget安装$yuminstallwget第二部分mysql安装1、下载mysql的repo源$wgethttp://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm2。安装mysql-community-release-el7-5.noarch.rpm包$sudorpm-ivhmysql-community-release-el7-5.noarch.rpm安装这个包后，你会得到两个mysqlYumrepo源：/etc/yum.repos.d/mysql-community.repo/etc/yum.repos.d/mysql-community-source.repo3.安装mysql$sudoyuminstallmysql-server4.重置mysql密码$mysql-uroot可能会报错这样的错误：ERROR2002(HY000):Can'tconnecttolocalMySQLserverthroughsocket'/var/lib/mysql/mysql.sock'(2)原因是/var/lib/mysql访问权限问题。以下命令将/var/lib/mysql的所有者更改为当前用户：$sudochown-Rroot:root/var/lib/mysql重启mysql服务$servicemysqldrestart5.然后登录重置密码：$mysql-uroot//直接回车进入mysql控制台mysql>usemysql;mysql>updateusersetpassword=password('newpassword')whereuser='要更新密码的用户名';mysql>flushprivileges;mysql>退出;6。再次登录$mysql-uroot-penterpassword：（直接输入新密码，然后回车即可）注：本文参考链接https://www.linuxidc.com/Linux...https://www.cnblogs.com/hafiz...百度云服务器可参考以下方法：1下载安装官方MySQLYumRepository$wget-i-chttp://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm使用上面的命令直接下载安装的YumRepository，大约25KB，然后直接用yum安装即可。$yum-yinstallmysql57-community-release-el7-10.noarch.rpm后，MySQL服务器将被安装。$yum-yinstallmysql-community-server至此，MySQL的安装就完成了，接下来就是对MySQL进行一些设置，具体方法同上。百度云服务器安装mysql方法参考链接：https://www.cnblogs.com/bigbr...https://www.cnblogs.com/lgqbo...https://www.cnblogs.com/bigbr...
