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.
#
#
# 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 directives 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
在配置文件末尾加上
SSLRandomSeed startup builtin
SSLRandomSeed connect builtin
SetHandler application/x-httpd-php
SetHandler application/x-httpd-php-source
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
