mysql community server 5.7.4_安装最新Mysql community server 5.7.10社区版的坑爹经历

shell> chown -R mysql data mysql-files

这一步都没出现什么错误，满以为安装成功了，然而执行下面这句

shell>bin/mysqld_safe --user=mysql &

却显示mysql启动错误！错误log没有记录下来，搞了半天也不知道错误在哪里，没办法，只好放弃这种安装。

2.接着使用yum方式安装

这是相对来说最简单的安装方式了，官方安装说明文档的url如下：

http://dev.mysql.com/doc/mysql-yum-repo-quick-guide/en/

按照文档中所述，先下载并安装mysql最新的镜像源，然后执行

# yum install mysql-community-server

非常顺利的完成了安装，因为有了上次的经历，心里很担心服务启动不了，接着执行

# service mysqld start

果然出问题了，mysqld启动错误，出现下面的提示：

Redirecting to /bin/systemctl start mysqld.service

Job for mysqld.service failed. See 'systemctl status mysqld.service' and 'journalctl -xn' for details.

# service mysqld status

Redirecting to /bin/systemctl status mysqld.service
