基本环境：VMware10.0+CentOS6.5+MySQL5.6.35
1、查看操作系统相关 shell> cat /etc/issue shell> uname -a 2、创建需要下载rpm软件包的目录 shell> mkdir -p /tools 3、是否有系统自带mysql的rpm包，如果有，需要删除自带的旧rpm包 shell> rpm -qa | grep -i mysql shell> yum -y remove mysql-libs-5.1* 4、MySQL官网下载安装MySQL-5.6.35所需的rpm软件包 shell> cd /tools shell> wget https://cdn.mysql.com//Downloads/MySQL-5.6/MySQL-server-5.6.35-1.el6.i686.rpm shell> wget https://cdn.mysql.com//Downloads/MySQL-5.6/MySQL-devel-5.6.35-1.el6.i686.rpm shell> wget https://cdn.mysql.com//Downloads/MySQL-5.6/MySQL-client-5.6.35-1.el6.i686.rpm 5、下载完之后，安装三个rpm软件包 shell> rpm -ivh MySQL-server-5.6.35-1.el6.i686.rpm shell> rpm -ivh MySQL-client-5.6.35-1.el6.i686.rpm shell> rpm -ivh MySQL-devel-5.6.35-1.el6.i686.rpm 6、修改配置文件位置 shell> cp /usr/share/mysql/my-default.cnf /etc/my.cnf shell> vim /etc/my.cnf [mysqld] #skip-grant-tables character_set_server=utf8 lower_case_table_names=1 max_connections=1000 datadir=/var/lib/mysql 7、初始化MySQL及修改MySQL默认的root密码 shell> service mysql start shell> service mysql status ##shell> /usr/bin/mysql_install_db shell> ps -ef | grep mysql shell> netstat -anpt | grep 3306 shell> more /root/.mysql_secret shell> mysql -uroot -pvzOCjNWBCZsuUlM8 mysql> select version(); ERROR 1820 (HY000): You must SET PASSWORD before executing this statement mysql> SET PASSWORD = PASSWORD('mysql5635'); 8、退出重新登录，并创建新用户 mysql> grant select,insert,update,delete on *.* to dba@"localhost" Identified by "mysql5635"; mysql> grant all privileges on *.* to dba@"%" Identified by "mysql5635"; #"%"只针对ip有效 #Win7系统连接虚拟机上的mysql http://www.2cto.com/database/201305/210279.html cmd> ping 192.168.85.128 #成功 cmd> telnet 192.168.85.128 3306 #失败 #确认是防火墙的原因 shell> service iptables stop #关闭之后telnet成功 shell> cat /etc/sysconfig/iptables #-I作为第一条规则插入，-A作为最后一条规则插入 shell> iptables -I INPUT -p tcp --dport 3306 -j ACCEPT shell> service iptables save shell> service iptables restart #win7系统cmd mysql -h192.168.85.128 -udba -p -P3306 #开机启动 shell> chkconfig mysql on shell> chkconfig mysql --list

You will find that password in '/root/.mysql_secret'. You must change that password on your first connect, no other statement but 'SET PASSWORD' will be accepted. See the manual for the semantics of the 'password expired' flag. Also, the account for the anonymous user has been removed. In addition, you can run: /usr/bin/mysql_secure_installation which will also give you the option of removing the test database. This is strongly recommended for production servers. See the manual for more instructions.
