5、错误
5.1 sqlyog连接时,报1130错误,是由于没有给远程连接的用户权限问题
解决1:更改 ‘mysql’数据库‘user’表‘host’项,从‘localhost’改成‘%’。
use mysql; select ‘host‘ from user where user=‘root‘; update user set host = ‘%‘ where user =‘root‘; flush privileges;
解决2:直接授权
GRANT ALL PRIVILEGES ON *.* TO ‘root’@‘%’ IDENTIFIED BY ‘youpassword’ WITH GRANT OPTION;
5.2 安装时的一些错误
-bash: ./scripts/mysql_install_db: /usr/bin/perl: bad interpreter: 没有那个文件或目录
解决: 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
解决:yum -y install libaio-devel
6、其他
6.1 配置环境变量
vi + /etc/profile
export PATH=....:/usr/local/mysql/bin
mysql在linux下的安装
