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;
修改root用户密码:
mysql> update mysql.user set password=PASSWORD('新密码') where User='root';
mysql> flush privileges;
mysql> quit
解决2:直接授权
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '新密码' WITH GRANT OPTION;
开端口:
/sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
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
db2start: error while loading shared libraries: libnuma.so.1: cannot open shared object file: No suc
解决办法:1.如果已经安装了libnuma.so.1,先yum remove libnuma.so.1
2.yum install numactl.x86_64
6、其他
6.1 配置环境变量
vi + /etc/profile
export PATH=....:/usr/local/mysql/bin
