命令：yum -y install autoconf
后面可能还会出现这个错误：Installing MySQL system tables.../usr/local/mysql/bin/mysqld: error while loading shared
原因：缺少libaio库文件
解决方法：yum install libaio* -y
后面还有可能出现这个错误:log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.
原因是没有/var/log/mariadb/mariadb.log这个路径,那我们就创建, 并给mysql用户授权即可
mkdir /var/log/mariadb
touch /var/log/mariadb/mariadb.log
chown -R mysql:mysql /var/log/mariadb/
再输入开启mysql服务, 搞定!
后面设置mysql密码时还可能遇到问题
执行下面这个试试
ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
-----------------------------------------------------------------------------------------------------------------------------------
设置软连接，mysql指令和mysqldump指令的
ln -s /usr/local/mysql/bin/mysql /usr/local/bin/bin
ln -s /usr/local/mysql/bin/mysqldump /usr/local/bin/mysqldump
