Centos6.5安裝MySQL5.6
1. 查看系統狀態
[root@itzhouq32 tools]# cat /etc/issue
CentOS release 6.5 (Final)
Kernel \r on an \m
[root@itzhouq32 tools]# uname -a
Linux itzhouq32 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
2.創建需要下載rpm軟體包的目錄
[root@itzhouq32 /]# mkdir soft
[root@itzhouq32 /]# cd soft
[root@itzhouq32 soft]# ls
[root@itzhouq32 soft]#
3. 查看系統中是否有已經存在的MySQL
如果有需要卸載
用這個查找
# rpm -qa | grep mysql
用這個卸載
yum -y remove mysql-libs-5.1*
4. 下載MySQL-5.6安裝包
分別執行下麵的三條命令
# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-server-5.6.21-1.rhel5.x86_64.rpm
# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-devel-5.6.21-1.rhel5.x86_64.rpm
# wget http://dev.mysql.com/Downloads/MySQL-5.6/MySQL-client-5.6.21-1.rhel5.x86_64.rpm
如果下載的速度太慢,也可以使用window下載後傳輸到虛擬機的這個目錄,然後安裝。
5. 安裝
# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
如果有以下報錯信息,需要安裝依賴包。
error: Failed dependencies:
libaio.so.1()(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.1)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
libaio.so.1(LIBAIO_0.4)(64bit) is needed by MySQL-server-5.6.21-1.rhel5.x86_64
執行:
# yum install -y libaio
再次安裝
# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm
# rpm -ivh MySQL-client-5.6.21-1.rhel5.x86_64.rpm

6. 修改配置文件位置
# cp /usr/share/mysql/my-default.cnf /etc/my.cnf
7. 初始化MySQL
# /usr/bin/mysql_install_db
# /etc/init.d/mysql start
# ps -ef | grep mysql
# netstat -anpt | grep 3306
# more /root/.mysql_secret
然後會顯示你的資料庫隨機碼
# The random password set for the root user at Fri Mar 15 01:43:14 2019 (local time): BKEIavP3r8C8wNoB
8. 登錄
# mysql -uroot -pBKEIavP3r8C8wNoB
登錄成功後會顯示版本信息
Warning: Using a password on the command line interface can be insecure.

mysql>
9. 設置新密碼
mysql> SET PASSWORD = PASSWORD('2626');
Query OK, 0 rows affected (0.00 sec)
mysql> EXIT
Bye
我設置了密碼為2626,並退出MySQL
10. 設置MySQL服務開機自啟動
# chkconfig mysql on
# chkconfig mysql --list
mysql 0:關閉 1:關閉 2:啟用 3:啟用 4:啟用 5:啟用 6:關閉
11. 檢查服務狀態
# service mysql status
SUCCESS! MySQL running (2447)
12. 開啟MySQL的遠程登錄
預設情況下MySQL為安全起見,不支持遠程登錄MySQL,所以需要設置開啟登錄MySQL的許可權。登錄MySQL後輸入命令:
mysql> grant all privileges on *.* to 'root' @'%' identified by '2626';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
其中2626是用於遠程訪問的密碼,可以與root密碼不一樣。這樣別的用戶遠程訪問你的資料庫時,可以使用root賬號,密碼2626登錄。
13. 開放Linux的對外訪問的埠
[root@itzhouq32 bin]# /sbin/iptables -I INPUT -p tcp --dport 3306 -j ACCEPT
[root@itzhouq32 bin]# /etc/rc.d/init.d/iptables save
iptables:將防火牆規則保存到 /etc/sysconfig/iptables: [確定]
[root@itzhouq32 bin]#
OK,打完收工了!
