Linux下apache+phppgadmin+postgresql安装配置
操作系统：CentOS
安装包：httpd(首选yum)， php(包括php以及php-pgsql,php-mbstring，首选yum)， phppgadmin ， postgresql 。
一、配置php项目部署环境
- 关闭Centos默认的selinux：
vi /etc/selinux/config
SELINUX=disabled
重启：
/sbin/init 6
- 安装apache（手动安装文件，如：httpd-2.4.4.tar.gz或yum安装均可）
[root@localhost conf]#yum install httpd
默认会安装到/etc/httd/下面
[root@localhost conf]# which httpd
/usr/sbin/httpd
安装完毕后，可以先启动服务service httpd start，然后到浏览器输入地址：http://host:80，正常会出现apache test page。
- 安装php（手动或者yum安装）
[root@localhost conf]#yum install php
[root@localhost conf]# which php
/usr/bin/php
[root@localhost conf]#yum install php-pgsql
[root@localhost conf]#yum install php-mbstring
二、安装并配置postgresql数据库
- 正常安装postgresql。
- 修改pg_hba.conf配置文件，使得数据库可以允许外部访问。
具体可以配置为：
# TYPE DATABASE USER ADDRESS METHOD
# "local" is for Unix domain socket connections only
local all all md5
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::1/128 trust
host all all 0.0.0.0/0 trust
三、部署并配置phPgAdmin
- 下载：phpPgAdmin-5.1.tar.gz ，并解压到到/var/www/ phpPgAdmin-5.1目录下；
- 配置所管理的数据库的参数：
[root@web-dev-machine phppgadmin]# vi /var/www/phppgadmin/conf/config.inc.php
其中必须修改的是：
$conf['extra_login_security'] = false;
其他的可以根据所管理的PostgreSQL数据库的安装情况类配置，如：
// Display name for the server on the login screen
$conf['servers'][0]['desc'] = 'PostgreSQL';
// Hostname or IP address for server. Use '' for UNIX domain socket.
// use 'localhost' for TCP/IP connection on this computer
$conf['servers'][0]['host'] = '192.168.100.101';
// Database port on server (5432 is the PostgreSQL default)
$conf['servers'][0]['port'] = 5432;
// Database SSL mode
// Possible options: disable, allow, prefer, require
// To require SSL on older servers use option: legacy
// To ignore the SSL mode, use option: unspecified
$conf['servers'][0]['sslmode'] = 'allow';
// Change the default database only if you cannot connect to template1.
// For a PostgreSQL 8.1+ server, you can set this to 'postgres'.
$conf['servers'][0]['defaultdb'] = 'template1';
// Specify the path to the database dump utilities for this server.
// You can set these to '' if no dumper is available.
$conf['servers'][0]['pg_dump_path'] = '/opt/pg932/bin/pg_dump';
$conf['servers'][0]['pg_dumpall_path'] = '/opt/pg932/bin/pg_dumpall';
注意：以上pg_dump_path和pg_dumpall_path在phpPgAdmin中执行导出数据库时才调用，所以一开始配置错误可能不会看到报错，执行导出时就会报错。
四、配置php 项目源文件目录以及监听端口
vi /etc/httpd/conf/httpd.conf
首先找到端口（默认为80,根据实际情况，可改可不改）
#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, in addition to the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to
# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)
#
#Listen 12.34.56.78:80
Listen 80
然后是php的文件目录（必须添加自己的项目的目录,可以直接添加到配置文件最后边）
#
# "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
#
<Directory "/var/www/cgi-bin">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>
#liuyy
#phpPgAdmin
Alias /phppgadmin "/var/www/phpPgAdmin"
<Directory "/var/www/phpPgAdmin">
Options Indexes Multiviews
AllowOverride None
Order allow,deny
Allow from all
</Directory>
注意：/phppgadmin才是在浏览器中要输入的地址，而不是文件名（phpPgAdmin）本身。
五、以上配置完毕后，在terminal中重启apache服务：service httpd restart
到浏览器中输入地址：http://ip:port/ phppgadmin (默认端口80 可以省略)
正常会出现phppgadmin的管理界面。
