cd /usr/local/mysql/<br>mkdir ./data/mysql
chown -R mysql:mysql ./
./scripts/mysql_install_db --user=mysql --datadir=/usr/local/mysql/data/mysql
cp support-files/mysql.server /etc/init.d/mysqld
chmod 755 /etc/init.d/mysqld
cp support-files/my-default.cnf /etc/my.cnf

#修改启动脚本
vi /etc/init.d/mysqld

#修改项：
basedir=/usr/local/mysql/
datadir=/usr/local/mysql/data/mysql

#启动服务
service mysqld start

#测试连接
./mysql/bin/mysql -uroot

#加入环境变量，编辑 /etc/profile，这样可以在任何地方用mysql命令了
export PATH=$PATH:/usr/local/mysql//bin<br>source /etc/profile

#启动mysql
service mysqld start
#关闭mysql
service mysqld stop
#查看运行状态
service mysqld status

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
