零PHP基础搭建phpMyAdmin连接远程数据库

一为什么写这篇博文？

由于项目特殊限制，不能从本机直接远程连接到DB ，只能通过一台中间server去访问DB,所以想要从本机直接访问DB需要在中间server上搭建一个phpMyAdmin，然后客户端通过访问phpMyAdmin来查询和修改DB。

二前提条件

具备一定的linux操作系统基础知识。

三 环境与软件版本

名称	版本
OS	RedHat x86_64
PHP	5.5.6
httpd	2.2.26
mysql	5.1.73
phpMyAdmin	4.0.9

下载地址：
PHP       http://us2.php.net/downloads.php
httpd      http://httpd.apache.org/download.cgi
mysql    http://dev.mysql.com/downloads/mysql/5.1.html#downloads

四环境搭建

1.httpd安装

要安装httpd首先需要安装好 apr，apr-util等依赖包，这里我就不详细介绍了，这里假设你已经准备好了httpd的依赖包。

我的依赖包安装路径为/usr/local。

下载好httpd-2.2.26.tar.gz

执行

tar xf httpd-2.2.26.tar.gz

cd httpd-2.2.26

./configure --enable-so

make

make install

httpd将会安装到默认路径/usr/local/apache2

进入

cd /usr/local/apache2/bin

执行

apachectl start

apachectl stop

如果不报错表示安装成功

httpd的配置文件

2.Mysql安装

下载 MySQL-community-5.1.73-1.rhel5.x86_64.rpm-bundle.tar

解压出来有很多rpm包

MySQL-client-community-5.1.73-1.rhel5.x86_64.rpm

MySQL-community-debuginfo-5.1.73-1.rhel5.x86_64.rpm

MySQL-devel-community-5.1.73-1.rhel5.x86_64.rpm

MySQL-embedded-community-5.1.73-1.rhel5.x86_64.rpm

MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm

MySQL-shared-community-5.1.73-1.rhel5.x86_64.rpm

MySQL-shared-compat-5.1.73-1.rhel5.x86_64.rpm

MySQL-test-community-5.1.73-1.rhel5.x86_64.rpm


执行 tar xf MySQL-community-5.1.73-1.rhel5.x86_64.rpm-bundle.tar

rpm -ivh MySQL-server-community-5.1.73-1.rhel5.x86_64.rpm

rpm -ivh MySQL-client-community-5.1.73-1.rhel5.x86_64.rpm

rpm -ivh *.rpm

默认会安装到/usr/bin;/usr/lib64/mysql/下面我们不需要配置mysql，只要安装好了就行了。php安装的时候需要用到/usr/lib64/mysql/下面的libmysqlclient.

3.PHP安装

下载php-5.5.6.tar.gz

执行

tar xf
php-5.5.6.tar.gz

cd
php-5.5.6.tar

 ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/ --with-mysqli=/usr/bin/mysql_config  --enable-mbstring --with-mysql-sock=/var/lib/mysql/mysql.sock --enable-embedded-mysqli --with-libdir=lib64

make

make install


cp php.ini-development /usr/local/lib/php.ini

PHP默认安装到/usr/local下面

查看版本信息

php -v


查看php配置信息

php-config


配置httpd

vim /usr/local/apache2/conf/httpd.conf


如果没有下面这一段就加上

LoadModule php5_module        modules/libphp5.so
修改DocumentRoot

DocumentRoot "/var/www/html/"
#
# This should be changed to whatever you set DocumentRoot to.
#
<Directory "/var/www/html/">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
#   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that "MultiViews" must be named *explicitly* --- "Options All"
# doesn't give it to you.
#
# The Options directive is both complicated and important.  Please see
# http://httpd.apache.org/docs/2.2/mod/core.html#options # for more information.
#
Options Indexes FollowSymLinks

#
# AllowOverride controls what dir
4000
ectives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
#   Options FileInfo AuthConfig Limit
#
AllowOverride None

#
# Controls who can get stuff from this server.
#
Order allow,deny
Allow from all

</Directory>

在配置文件末尾加上

<IfModule ssl_module>
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
</IfModule>

<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch>
<FilesMatch "\.phps$">
SetHandler application/x-httpd-php-source
</FilesMatch>

保存关闭

wq

4.安装phpMyAdmin

下载phpMyAdmin-4.0.9-all-languages.zip

执行

unzip phpMyAdmin-4.0.9-all-languages.zip

cp phpMyAdmin-4.0.9-all-languages  /var/www/html/phpMyAdmin


cd /var/www/html/phpMyAdmin


cp config.sample.inc.php config.inc.php

修改config.inc.php的内容如下

$cfg['blowfish_secret'] = 'a8b7c6d';
/*
* Servers configuration
*/
$i = 0;

/*
* First server
*/
$i++;
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '10.123.255.1'; //your host ip
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['compress'] = false;
/* Select mysql if your server does not have mysqli */
$cfg['Servers'][$i]['port'] = '3306'; // MySQL port
$cfg['Servers'][$i]['extension'] = 'mysql';
$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['user']          = 'test';  // your mysql user
$cfg['Servers'][$i]['password']      = 'test'; // use here your password
$cfg['UploadDir'] = '';
$cfg['SaveDir'] = '';

5.程序启动

做完以上步骤之后所有的程序安装完毕启动你的httpd访问http://yourhost:yourport/phpMyAdmin/index.php就可以看到如下画面



输入mysql的用户名密码可以进入一下画面
