Phabricator is an advanced open source software development platform which can be used to: - Review and audit code. - Host Git/Hg/SVN repos. - Track bugs. - Manage projects. - Communicate with team members. - And do much more! Thanks to its abundant features and exceptional performance, Phabricator is getting more and more popular in the open source software community. In this article, I will show you how to install Phabricator on a Vultr CentOS 7 server instance. ## Prerequisites - Deploy a Vultr CentOS 7 server instance from scratch; - Log in from the SSH terminal using a non-root sudo user. ## Step 1: System update Update your CentOS 7 system, then reboot: yum update -y && shutdown -r now After the system boots, log in as a non-root user with sudo access. ## Step 2: Install MariaDB Install the MariaDB server: sudo yum install mariadb mariadb-server Start and enable the MariaDB service: sudo systemctl start mariadb.service sudo systemctl enable mariadb.service For security purposes, run the MySQL secure installation utility: sudo /usr/bin/mysql_secure_installation Finish this process in accordance with the instructions below: Enter current password for root (enter for none): Enter Set root password? [Y/n]: Y New password: Re-enter new password: Remove anonymous users? [Y/n]: Y Disallow root login remotely? [Y/n]: Y Remove test database and access to it? [Y/n]: Y Reload privilege tables now? [Y/n]: Y ## Step 3: Install Apache Install the Apache web server using YUM: sudo yum install httpd Modify the default configuration in order to enhance security: sudo sed -i 's/^/#&/g' /etc/httpd/conf.d/welcome.conf sudo sed -i "s/Options Indexes FollowSymLinks/Options FollowSymLinks/" /etc/httpd/conf/httpd.conf Start and enable the Apache service: sudo systemctl start httpd.service sudo systemctl enable httpd.service ## Step 4: Install PHP Install PHP and necessary extensions: sudo yum install php php-mysqli php-mbstring php-gd php-curl php-cli php-common php-process ## Step 5: Install git sudo yum install git ## Step 6: Download and install Phabricator cd ~ mkdir phabricator cd phabricator git clone https://github.com/phacility/libphutil.git git clone https://github.com/phacility/arcanist.git git clone https://github.com/phacility/phabricator.git cd ~ sudo chown -R apache: ~/phabricator sudo mv ~/phabricator /var/www/html ## Step 7: Setup a virtual host for Phabricator sudo vi /etc/httpd/conf.d/phabricator.conf Populate the following code segment: __Note:__ You need to replace `admin@example.com`, `phabricator.example.com`, `www.phabricator.example.com`, `/var/log/httpd/phabricator.example.com-error_log`, and `/var/log/httpd/phabricator.example.com-access_log` with your own values. ServerAdmin admin@example.com DocumentRoot /var/www/html/phabricator/phabricator/webroot/ ServerName phabricator.example.com ServerAlias www.phabricator.example.com RewriteEngine on RewriteRule ^/rsrc/(.*) - [L,QSA] RewriteRule ^/favicon.ico - [L,QSA] RewriteRule ^(.*)$ /index.php?__path__=$1 [B,L,QSA] AllowOverride All ErrorLog /var/log/httpd/phabricator.example.com-error_log CustomLog /var/log/httpd/phabricator.example.com-access_log common Save and quit: :wq Restart the Apache service in order to put your modifications into effect: sudo systemctl restart httpd.service ## Step 8: Setup the MariaDB credentials for Phabricator Before you can use Phabricator, you need to setup the MariaDB credentials: cd /var/www/html/phabricator/phabricator/ sudo ./bin/config set mysql.host localhost sudo ./bin/config set mysql.port 3306 sudo ./bin/config set mysql.user root sudo ./bin/config set mysql.pass Populate Phabricator schemes: ./bin/storage upgrade During this process, you need to input "y" twice: Before running storage upgrades, you should take down the Phabricator web interface and stop any running Phabricator daemons (you can disable this warning with --force). Are you ready to continue? [y/N] y ... MySQL needs to copy table data to make some adjustments, so these migrations may take some time. Fix these schema issues? [y/N] y ## Step 9: Modify firewall rules and setup a Phabricator admin account You need to allow inbound traffic on default HTTP port 80: sudo firewall-cmd --zone=public --permanent --add-service=http sudo firewall-cmd --reload Then use your web browser to visit: http:// You will be presented with the Phabricator registration web page. Create an administrator account for daily management. Now, let's have a look at how to configure Phabricator. ## Step 10: Fix unresolved setup issues Before you can use Phabricator with a peace of mind, you have to fix several setup issues. The number of setup issues varies, in my case, there were 16. Let's solve them one by one. ### Issue 1: Base URI Not Configured Click the "Base URI Not Configured" link to get into the issue details page in which you can learn more about this issue. In order to fix this issue, you need to execute the following commands on your SSH terminal. Be sure to use the proper IP address. cd /var/www/html/phabricator/phabricator/ sudo ./bin/config set phabricator.base-uri 'http://' Then in your web browser, click the "Reload Page" button on the issue details page. If your repair worked, the text on the page will become "Issue Resolved". Click the "Return to Open Issue List" link to investigate other issues. ### Issue 2: No Authentication Providers Configured Click the "No Authentication Providers Configured" link to get into the issue details page. In order to fix this issue, you need to specify the authentication provider. Click the "Auth Application" link and then the "+ Add Provider" button to get into the "Add Auth Provider" page. Choose an appropriate authentication provider, and then click the "Continue" button. Here I chose "Username/Password". In the "Add Auth Provider: Username/Password" page, you can review more detailed settings, then click the "Add Provider" button. You can add more authentication providers in the same fashion, but for now, click the "You have X unresolved setup issues..." link to handle other issues. ### Issue 3: Phabricator Daemons Are Not Running Click the "Phabricator Daemons Are Not Running" link to enter the details page. In order to solve this issue, run the command below on your SSH terminal: cd /var/www/html/phabricator/phabricator/ ./bin/phd start Click the "Reload Page" button to confirm the result. ### Issue 4: PHP `post_max_size` Not Configured Run the following commands on your SSH terminal to fix this issue: sudo sed -i "s/post_max_size = 8M/post_max_size = 32M/" /etc/php.ini sudo systemctl restart httpd.service Click the "Reload Page" button to confirm your modifications. ### Issue 5-10: MySQL-related issues There are six MySQL-related issues in total: - Small MySQL "max_allowed_packet" - MySQL STRICT_ALL_TABLES Mode Not Set - MySQL is Using Default Stopword File - MySQL is Using Default Minimum Word Length - MySQL is Using the Default Boolean Syntax - MySQL May Run Slowly As a matter of convenience, let's fix them in one batch. On your SSH terminal, edit the MySQL configuration file with `vi`: sudo vi /etc/my.cnf Under the three lines on the top: [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock Add the six lines below: max_allowed_packet=32M sql_mode=STRICT_ALL_TABLES ft_stopword_file=/var/www/html/phabricator/phabricator/resources/sql/stopwords.txt ft_min_word_len=3 ft_boolean_syntax=' |-><()~*:""&^' innodb_buffer_pool_size=1600M # about 40% of your system memory __Warning:__ You need to set a proper Innodb buffer pool size according to your specific server size. Usually, the Innodb buffer pool size should be about 40% of the amount of your machine's memory. For example, if you are using a machine with 4G memory, the reasonable Innodb buffer pool size would be 1600M. In case that you are using a machine with little memory (such as 768M), you may need to assign a size less than 40% of the amount of your machine's memory (say 220M) in order to save more memory for the system. Save and quit: :wq Restart the MariaDB service: sudo systemctl restart mariadb.service Finally, run the following command: mysql -u root -p -e "REPAIR TABLE phabricator_search.search_documentfield" Click the "Reload Page" button to examine your efforts. ### Issue 11: Install Pygments to Improve Syntax Highlighting On CentOS 7, Pygments has been installed but not enabled by default, you need to enable it manually: Click the link: Edit "pygments.enabled", Choose "Use Pygments" from the "Database Value" drop-down menu, then click the "Save Config Entry" button. ### Issue 12: Server Timezone Not Configured Modify the `php.ini` file: sudo vi /etc/php.ini Replace the line: ;date.timezone = With: date.timezone = America/Los_Angeles Save and quit: :wq __Note:__ "America/Los_Angeles" is the timezone value of my machine, you need to find the appropriate timezone value for your own server instance [here](https://secure.php.net/manual/en/timezones.php). Restart the Apache service: sudo systemctl restart httpd.service Click the "Reload Page" button to examine the result. ### Issue 13: Large File Storage Not Configured You need to deploy a proper large file storage solution according to your own setting. For now, you can click the "Ignore Setup Issue" button to skip. ### Issue 14: Alternate File Domain Not Configured Say you have set up an alternate file domain or a CDN, then in the SSH terminal: cd /var/www/html/phabricator/phabricator/ sudo ./bin/config set security.alternate-file-domain Click the "Reload Page" button to examine the result. ### Issue 15: Missing Repository Local Path Use the following commands to solve this issue: sudo mkdir /var/repo sudo chown apache: /var/repo Click the "Reload Page" button to examine the result. ### Issue 16: PHP Extension 'APC' Not Installed sudo yum install php-pear php-devel httpd-devel pcre-devel gcc make sudo pecl install apc During the installation process of APC, always press Enter to use the default option. sudo vi /etc/php.ini Add the four lines to the end of the file: extension=apc.so apc.write_lock = On apc.slam_defense = Off apc.stat = Off Save and quit: :wq Restart the Apache service: sudo systemctl restart httpd.service Click the "Reload Page" button to check the result. That's all. Happy coding!
