之前曾经写过关于RHEL6.5的安装还有网络yum的配置不会的请参考以下两篇文章
系统安装https://www.cnblogs.com/lch1990/p/10310304.html
yum配置https://www.cnblogs.com/lch1990/p/10299714.html
好了既然要装mysql我们就去mysql官网下载最新的安装包吧
https://dev.mysql.com/downloads/mysql/
这里就不登录仅下载了
或者你可以将此处的链接复制出来直接在RHEL上面wget一下直接上命令吧
[root@localhost ~]# mkdir /download
[root@localhost ~]# cd /download/
[root@localhost download]# yum -y install wget
略过安装过程。。。
[root@localhost download]# wget https://dev.mysql.com/get/Downloads/MySQL-8.0/mysql-community-server-8.0.14-1.el6.x86_64.rpm
略过下载过程。。。
解压安装吧
[root@localhost download]# ls
mysql-8.0.14-1.el6.x86_64.rpm-bundle.tar
[root@localhost download]# tar -xf mysql-8.0.14-1.el6.x86_64.rpm-bundle.tar
[root@localhost download]# ll

接下来就开始安装吧，这里提供一个非常简单的方法一条命令搞定
[root@localhost download]# yum -y install mysql-community-*
你没看错就这一条命令然后就静等yum为你解决一切依赖关系吧
[root@localhost download]# service mysqld status
mysqld is stopped
[root@localhost download]# service mysqld start
Starting mysqld: [ OK ]
不错服务成功启动了说明安装没问题了继续往下吧
修改MySQL配置文件：vim /etc/my.cnf，在文件末尾加上：skip-grant-tables，保存后重启MySQL服务：service mysqld restart，然后重新登录
[root@localhost download]# cat /etc/my.cnf
# For advice on how to change settings please see
# http://dev.mysql.com/doc/refman/8.0/en/server-configuration-defaults.html
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove the leading "# " to disable binary logging
# Binary logging captures changes between backups and is enabled by
# default. It's default setting is log_bin=binlog
# disable_log_bin
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
#
# Remove leading # to revert to previous value for default_authentication_plugin,
# this will increase compatibility with older clients. For background, see:
# https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_default_authentication_plugin
# default-authentication-plugin=mysql_native_password
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
skip-grant-tables
[root@localhost download]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
[root@localhost download]#
接下来我们就可以登录了（首次登录没有密码直接回车）
[root@localhost download]# mysql -u root -p
