redhat6.3安装MySQL-server-5.6.13-1.el6.x86_64.rpm

首先下载下面三个文件：

[root@localhost download]# rpm -ivh --replacefiles MySQL-server-5.6.13-1.el6.x86_64.rpm   
Preparing...                ########################################### [100%]  
   1:MySQL-server           ########################################### [100%]  
[root@localhost download]# rpm -ivh --replacefiles MySQL-client-5.6.13-1.el6.x86_64.rpm   
Preparing...                ########################################### [100%]  
   1:MySQL-client           ########################################### [100%]  
[root@localhost download]# rpm -ivh --replacefiles MySQL-devel-5.6.13-1.el6.x86_64.rpm   
Preparing...                ########################################### [100%]  
   1:MySQL-devel            ########################################### [100%]要移除安装可以使用 rpm -e MySQL-server  、 rpm -e MySQL-devel、MySQL-client即可；
2. 初始化数据库： 
/usr/bin/mysql_install_db 
3. 启动mysql服务：
service mysql start
使用命令ps -ef | grep mysql 查看mysql进程：
[root@localhost ~]# ps -ef | grep mysql  
root     26047     1  0 18:14 pts/12   00:00:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/localhost.localdomain.pid  
mysql    26227 26047  0 18:14 pts/12   00:00:01 /usr/sbin/mysqld --basedir=/usr --datadir=/var/lib/mysql --plugin-dir=/usr/lib64/mysql/plugin --user=mysql --log-error=/var/log/mysqld.log --pid-file=/var/lib/mysql/localhost.localdomain.pid --socket=/var/lib/mysql/mysql.sock  
root     26545 24726  0 18:27 pts/8    00:00:00 grep mysql
4.第一次登陆设置root密码：
首先查看 cat /root/.mysql_secret
root@localhost ~]# cat /root/.mysql_secret   
# The random password set for the root user at Fri Aug 30 15:57:18 2013 (local time): fMYcarvB
然后命令行：mysql -u root -p ，然后输入上面的密码即可：
[root@localhost ~]# mysql -u root -p  
Enter password:   
Welcome to the MySQL monitor.  Commands end with ; or \g.  
Your MySQL connection id is 5  
Server version: 5.6.13 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
设置root密码： 
mysql> use mysql  
Database changed  
mysql> update user set password=password('root') where user='root';  
Query OK, 0 rows affected (0.15 sec)  
Rows matched: 5  Changed: 0  Warnings: 0  
  
mysql> flush privileges;  
Query OK, 0 rows affected (0.00 sec)
退出，重新登陆即可使用新的密码登陆；
5. 设置远程登陆：
使用root登陆到mysql后
mysql> update user set host='%' where user='root';  
ERROR 1062 (23000): Duplicate entry '%-root' for key 'PRIMARY'  
mysql> select host,user from user;  
+-----------------------+------+  
| host                  | user |  
+-----------------------+------+  
| %                     | root |  
| 127.0.0.1             | root |  
| 192.168.128.142       | root |  
| ::1                   | root |  
| localhost.localdomain | root |  
+-----------------------+------+  
5 rows in set (0.00 sec)
然后：  
mysql> grant all privileges on *.* to 'root'@'%' with grant option;  
Query OK, 0 rows affected (0.08 sec)  
  
mysql> exit  
Bye  
[root@localhost ~]# service mysql restart  
Shutting down MySQL.. SUCCESS!   
Starting MySQL.. SUCCESS!   
重启mysql即可远程登陆。
分享，快乐，成长
