Centos6.5安裝MySQL5.6備忘記錄

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.建立須要下載rpm軟件包的目錄

[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

若是有須要卸載
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

分別執行下面的三條命令

# 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

若是下載的速度太慢，也能夠使用window下載後傳輸到虛擬機的這個目錄，而後安裝。

5. 安裝

# rpm -ivh MySQL-server-5.6.21-1.rhel5.x86_64.rpm

若是有如下報錯信息，須要安裝依賴包。

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 
Preparing...                ########################################### [100%]
   1:MySQL-client           ########################################### [100%]

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

而後會顯示你的數據庫隨機碼

# The random password set for the root user at Fri Mar 15 01:43:14 2019 (local time): BKEIavP3r8C8wNoB

8. 登陸

# mysql -uroot -pBKEIavP3r8C8wNoB

登陸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

我設置了密碼爲2626，並退出MySQL

10. 設置MySQL服務開機自啓動

# chkconfig mysql on
# chkconfig mysql --list
mysql              0:關閉    1:關閉    2:啓用    3:啓用    4:啓用    5:啓用    6:關閉

11. 檢查服務狀態

# service mysql status
 SUCCESS! MySQL running (2447)

12. 開啓MySQL的遠程登陸

默認狀況下MySQL爲安全起見，不支持遠程登陸MySQL，因此須要設置開啓登陸MySQL的權限。登陸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，能夠與root密碼不同。這樣別的用戶遠程訪問你的數據庫時，能夠使用root帳號，密碼2626登陸。

13. 開放Linux的對外訪問的端口

[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：     [肯定]
[root@itzhouq32 bin]#

OK，打完收工了！
