5、錯誤
5.1 sqlyog連接時，報1130錯誤，是由於沒有給遠程連接的用戶權限問題
解決1:更改 ‘mysql’數據庫‘user’表‘host’項，從‘localhost’改成‘%’。
use mysql; select ‘host‘ from user where user=‘root‘; update user set host = ‘%‘ where user =‘root‘; flush privileges;
解決2：直接授權
GRANT ALL PRIVILEGES ON *.* TO ‘root’@‘%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
5.2 安裝時的一些錯誤
-bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 沒有那個文件或目錄
解決： yum -y install perl perl-devel
Installing MySQL system tables..../bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解決：yum -y install libaio-devel
6、其他
6.1 配置環境變量
vi + /etc/profile
export PATH=....:/usr/local/mysql/bin
