    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
    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; 

      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
