安裝方式使用的是官網的安裝腳本，官網的安裝教程：
https://secure.phabricator.com/book/phabricator/article/installation_guide/
主要安裝過程說明：
1、從官網下載安裝腳本（將會安裝apache、php等環境，不會安裝mysql）
2、執行腳本
1）將腳本上傳到將要安裝的服務器的相關目錄，如/usr/local/phabricator
2）添加執行權限
chmod +x install_rhel-derivs.sh
3）執行安裝腳本
cd /usr/local/phabricator
./install_rhel-derivs.sh
3、配置Apache，官網配置說明：
https://secure.phabricator.com/book/phabricator/article/configuration_guide/
1）把配置文件中的下面一段配置註釋掉，因爲默認配置/目錄是禁止所有訪問
#<Directory />
# AllowOverride none
# Require all denied
#</Directory>
2）添加如下配置到文件中
<VirtualHost *>
# Change this to the domain which points to your host.
ServerName cr.gsafety.com
# Change this to the path where you put 'phabricator' when you checked it
# out from GitHub when following the Installation Guide.
#
# Make sure you include "/webroot" at the end!
DocumentRoot /usr/local/phabricator/phabricator/webroot
RewriteEngine on
RewriteRule ^(.*)$ /index.php?__path__=$1 [B,L,QSA]
</VirtualHost>
<Directory "/usr/local/phabricator/phabricator/webroot">
Order allow,deny
Allow from all
</Directory>
3）打開ServerName，默認是註釋掉的。
4) 啓動Apache
/usr/sbin/httpd -k start
或
/usr/sbin/httpd -k restart
4、修改/etc/hosts（如果沒有域名的話）
5、安裝MySQL（略）
6、使用./bin/config配置數據庫
cd /usr/local/phabricator/phabricator/
./bin/config set mysql.host 192.168.46.1
./bin/config set mysql.user root
./bin/config set mysql.pass 123456
7、升級php版本到5.5以上
yum list installed|grep php
yum remove php
yum remove php-*
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
yum -y install php71-php php71-php-common php71-php-devel php71-php-gd php71-php-mysqlnd php71-php-pecl-mysql php71-php-pecl-memcached php71-php-pecl-memcache php71-php-pecl-redis php71-php-opcache php71-php-mbstring php71-php-posix php71-php-apcu php71-php-zip
php -v
8、執行./bin/storage upgrade，完成
9、附錄：
主要操作命令記錄：
cd /usr/local/
mkdir phabricator
cd phabricator/
./install_rhel-derivs.sh
vim /etc/httpd/conf/httpd.conf
vi /etc/hosts
ping cr.gsafety.com
/usr/sbin/httpd -k restart
firewall-cmd --state
systemctl stop firewalld
cd /usr/local/phabricator/
cd phabricator/
./bin/storage upgrade
which php
php -v
yum list installed|grep php
yum remove php
yum remove php-*
rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
yum -y install php72-php php72-php-common php72-php-devel php72-php-gd php72-php-mysqlnd php72-php-pecl-mysql php72-php-pecl-memcached php72-php-pecl-memcache php72-php-pecl-redis php72-php-opcache
php -v
which php
find / -name php
/opt/remi/php72/root/usr/bin/php -v
vi .bash_profile
source .bash_profile
php -v
cd /usr/local/phabricator/phabricator/
./bin/config set mysql.host 192.168.46.1
