CentOS7安装mysql5.7解压缩版简明教程

解决：需要新建data目录，指定安装目录(在非默认目录时需要指定，默认路径：/usr/local/mysql，同时需要指定./support-files/mysql.server中的basedir和datadir为相应路径)。

[root@localhost mysql-5.7.13]# ./bin/mysql_install_db --user=mysql --basedir=/usr/local/mysql-5.7.13/ --datadir=/usr/local/mysql-5.7.13/data/ 2016-06-26 02:48:47 [WARNING] mysql_install_db is deprecated. Please consider switching to mysqld --initialize 2016-06-26 02:49:19 [WARNING] The bootstrap log isn't empty: 2016-06-26 02:49:19 [WARNING] 2016-06-26T09:48:50.798592Z 0 [Warning] --bootstrap is deprecated. Please consider using --initialize instead 2016-06-26T09:48:50.898732Z 0 [Warning] Changed limits: max_open_files: 1024 (requested 5000) 2016-06-26T09:48:50.898778Z 0 [Warning] Changed limits: table_open_cache: 431 (requested 2000)

以上报错均因未在mysql.server中指定自定义的路径。

若是还提示已经有data文件了 删除了它，新建即可

希望本文所述对大家CentOS服务器维护有所帮助。
