前言:php
由於工做的緣由,不少地方須要用到數據庫查詢,爲了不破壞真實存在的數據庫,因此,我搭建了一個虛擬機,在搭建的虛擬機上將數據庫進行了導入。這裏,用了一個PHP myAdmin的工具,我的以爲仍是很是方便控制管理數據庫的。故作了下研究,寫下此文章記錄下。html

Complete!
root@cent42:/var/www/html>
2)啓動服務器
root@cent42:/root> service mysqld start
Initializing MySQL database: WARNING: The host 'cent42' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cent42 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[ OK ]
Starting mysqld: [ OK ]
3)放通防火牆
使用命令以下:
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT (關於iptabls的詳細解釋請見iptables章節)
4) 執行安全性設置
包括設置root密碼、刪除測試數據庫等:這裏設置root密碼將是你登錄數據庫使用的密碼)
root@cent42:/root> /usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!
root@cent42:/root>
在「/etc/sysconfig/iptables」文件中「-A INPUT ... --dport 22 -j ACCEPT」一行後面添加放通80端口的規則。具體命令以下:
"-A INPUT -p tcp -m state --state NEW -m tcp --dport 80 -j ACCEPT"
重啓防火牆(service iptables restart)
上述操做完成後,你能夠經過瀏覽器去訪問以下的地址(地址就是你搭建虛擬機的地址)
http://135.251.124.24/
會出現一個Apache的界面
如今,你只要在服務器的「/var/www/html/」這個目錄中添加相關的html文件,就能夠訪問了。
3.安裝PHP
yum install php php-mysql
這裏僅僅安裝了PHP軟件自己,和用於php-mysql鏈接的庫,實際在訪問PHP的時候,還須要裝其餘的插件,因此,如何找打和PHP相關的插件呢?可使用以下命令:
yum search php-,這裏命令能夠列出全部的PHP的安裝包,若是你想知道每一個模塊是幹什麼的,可使用「yum info php-common」這樣的命令去查看
安裝完成後,須要重啓Apache HTTP Server :
service httpd restart
測試下PHP是否安裝成功,可否解析PHP代碼。進入以下目錄:
cd /var/www/html/
編輯以下文件:
root@cent42:/var/www/html> vi info.php
添加以下信息:
<?php
phpinfo();
?>
保存退出後,瀏覽器中輸入:
http://135.251.124.24//info.php,應該就能夠看到PHP的網頁了。
安裝phpMyAdmin
找到一個phpMyAdmin的包,將其放在你的服務器上,我是直接放在了/var/www/html下,而後解壓,將名稱更改成phpMyAdmin便可。這樣,你就能夠經過訪問http://135.252.4.25/phpMyAdmin/來訪問phpMyAdmin,從而來訪問管理你的數據庫了。
用戶名就是root,密碼就是你在上面設置的密碼。
4.如何導入導出數據庫
若是你有一個源數據庫,你想將它導入到你搭建的服務器上,那麼應該如何實現呢,能夠用以下的命令:
先經過以下命令到源數據庫中將數據導出:
mysqldump --password=xxx(密碼) --user=root(用戶) --add-drop-table --databases xxx(源DB的名字) --result-file=/home/xxx.sql(目標)
而後登錄到目標數據庫(我這裏就是登錄到24上),建立一個新的database:
mysqladmin --user=root --password=xxx create mh_db_bak_20160811
而後將剛纔導出的文件上傳到目標數據庫的同一個服務器上(經過FTP等先將導出的數據庫傳入到你的目標服務器上),執行下面的命令導入文件:
mysql --user=root --password=xxx mh_db_bak_20160811 < cif4db.sql
這樣,你打開你的PHPMyAdmin的時候,就能夠看到導入的數據庫了,能夠執行你的查詢等操做啦。
