CentOS下安装MySQL-server-5.6

在RedHat 6.3下安装MySQL-server-5.6.13-1.el6.x86_64.rpm

首先下载下面三个文件：

MySQL-client-5.6.13-1.el6.x86_64.rpm
MySQL-devel-5.6.13-1.el6.x86_64.rpm
MySQL-server-5.6.13-1.el6.x86_64.rpm

然后使用root账号登陆，进行安装：

1. 安装server、devel、client：1. 安装server、devel、client：

rpm -ivh --replacefiles MySQL-s*.rpm

rpm -ivh --replacefiles MySQL-d*.rpm

rpm -ivh --replacefiles MySQL-c*.rpm

[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.

 

注意：

MySql5.6操作时报错：You must SET PASSWORD before executing this statement解决 
mysql> SET PASSWORD = PASSWORD('123456'); 
Query OK, 0 rows affected (0.03 sec) 
mysql> create database roger; 
Query OK, 1 row affected (0.00 sec) 
也就是用mysql> SET PASSWORD = PASSWORD('123456');这句话重新设置一次密码！

 

 

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。
