# OpenVK Installation Instructions
* * *
1. Install Composer, Node.js, Yarn and [Chandler](https://github.com/openvk/chandler)
2. Install [commitcaptcha](https://github.com/openvk/commitcaptcha)/[chandler-recaptcha](https://github.com/openvk/chandler-recaptcha) and OpenVK as Chandler extensions and enable them like this:
```bash
ln -s /path/to/chandler/extensions/available/commitcaptcha /path/to/chandler/extensions/enabled/
ln -s /path/to/chandler/extensions/available/openvk /path/to/chandler/extensions/enabled/

3. Import install/init-static-db.sql to same database you installed Chandler to
4. Import install/init-event-db.sql to separate database
5. Rename openvk-example.yml to openvk.yml and change options
6. Run `composer install` in OpenVK directory

# Installing OpenVK
Based on [@rem-pai](https://github.com/rem-pai)'s way to install OpenVK modified using my experience.
## SELinux
🖥Run the command:
```bash
sestatus
```
If it says `SELinux status: enabled` then SELinux will disturb us. Let's disable it.
_Note: I know that it's not most secured solution but I don't know any proper way that will work._
📝Edit file `/etc/sysconfig/selinux` and change the line `SELinux=enforcing` to `SELinux=disabled`, then 🔌reboot your machine. `sestatus` should tell `SELinux status: disabled` right now.
## Dependencies
🖥Let's install EPEL and Remi repos for PHP 7.4:
```bash
dnf -y install epel-release
dnf -y install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
```
🖥Then enable modules that we need:
```bash
dnf -y module enable php:remi-7.4
dnf -y module enable nodejs:14
```
🖥And install dependencies:
```bash
dnf -y install php php-cli php-common unzip php-zip php-yaml php-gd php-pdo_mysql nodejs git
```
🖥Don't forget about Yarn and Composer:
```bash
npm i -g yarn
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php composer-setup.php --filename=composer2 --install-dir=/bin --snapshot
rm composer-setup.php
```
### Database
🖥We will use Percona Server for DB:
```bash
dnf -y install https://repo.percona.com/yum/percona-release-latest.noarch.rpm
percona-release setup -y ps80
dnf -y install percona-server-server percona-toolkit
systemctl start mysql
```
🖥And then look up for temporary password:
```bash
cat /var/log/mysqld.log | grep password
```
It should look like this:
2021-01-11T12:56:09.203991Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: >b?Q.fDXJ4fk
🖥Then run `mysql_secure_installation`, set new password and answer like this:
Change the password for root ? ((Press y|Y for Yes, any other key for No) : n
Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
### ffmpeg
Additionally, you can install ffmpeg for processing videos.
🖥You will need to use RPMFusion repo to install it:
```bash
dnf -y localinstall --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm
dnf -y install --nogpgcheck https://download1.rpmfusion.org/free/el/rpmfusion-free-release-8.noarch.rpm
```
🖥Then install SDL2 and ffmpeg:
```bash
dnf -y install http://rpmfind.net/linux/epel/7/x86_64/Packages/s/SDL2-2.0.10-1.el7.x86_64.rpm
dnf -y install ffmpeg
```
## Chandler and OpenVK installation
🖥Install Chandler in `/opt`:
```bash
cd /opt
git clone https://github.com/openvk/chandler.git
cd chandler/
composer2 install
```
🖥You will need a secret key. You can generate it using:
```bash
cat /dev/random | tr -dc 'a-z0-9' | fold -w 128 | head -n 1
```
📝Now edit config file `chandler-example.yml` like this:
```yaml
chandler:
debug: true
websiteUrl: null
rootApp: "openvk"
preferences:
appendExtension: "xhtml"
adminUrl: "/chandlerd"
exposeChandler: true
database:
dsn: "mysql:unix_socket=/var/lib/mysql/mysql.sock;dbname=db"
user: "root"
password: "DATABASE_PASSWORD"
security:
secret: "SECRET_KEY_HERE"
csrfProtection: "permissive"
sessionDuration: 14
```
🖥And rename it to `chandler.yml`:
```bash
mv chandler-example.yml chandler.yml
```
🖥Now let's install CommitCaptcha extension. It is mandatory for OpenVK.
```bash
cd extensions/available/
git clone https://github.com/openvk/commitcaptcha.git
cd commitcaptcha/
composer2 install
```
🖥And now download OpenVK:
```bash
cd ..
git clone https://github.com/openvk/openvk.git
cd openvk/
composer2 install
cd Web/static/js
yarn install
```
📝Now edit config file `openvk-example.yml` like this:
```yaml
openvk:
debug: true
appearance:
name: "OpenVK"
motd: "Yet another OpenVK instance"
preferences:
femaleGenderPriority: true
uploads:
disableLargeUploads: false
mode: "basic"
shortcodes:
forbiddenNames:
- "index.php"
security:
requireEmail: false
requirePhone: false
forcePhoneVerification: false
forceEmailVerification: false
enableSu: true

maxViolations: 50
maxViolationsAge: 120
autoban: true

adminAccount: 1 # Change this ok

bellsAndWhistles:
fartscroll: false
testLabel: false
credentials:
smsc:

client: ""
secret: ""
eventDB:
enable: true # Better enable this
database:
dsn: "mysql:unix_socket=/var/lib/mysql/mysql.sock;dbname=openvk_eventdb"
user: "root"
password: "DATABASE_PASSWORD"
```
Please note `eventDB` section because it's better to enable event database.
🖥And rename it to `openvk.yml`:
```bash
mv openvk-example.yml openvk.yml
```
🖥Then enable CommitCaptcha and OpenVK for Chandler:
```bash
ln -s /opt/chandler/extensions/available/commitcaptcha/ /opt/chandler/extensions/enabled/commitcaptcha
ln -s /opt/chandler/extensions/available/openvk/ /opt/chandler/extensions/enabled/openvk
```
### DB configuration
_Note: it's better to create another user for SQL but I won't cover that._
🖥Enter MySQL shell:
```bash
mysql -p
```
🖥And create main and event databases:
```sql
CREATE DATABASE openvk;
CREATE DATABASE openvk_eventdb;
exit
```
🖥Go to `/opt/chandler`:
```bash
cd /opt/chandler
```
📝We need to import Chandler database but for some reason it's not ready for use so we need to edit dump `install/init-db.sql`:
1\. Remove ` PAGE_CHECKSUM=1` everywhere.
2\. Replace `Aria` with `InnoDB` everywhere.
🖥Now database dump can be imported:
```bash
mysql -p'DATABASE_PASSWORD' openvk < install/init-db.sql
```
🖥Go to `extensions/available/openvk/`:
```bash
cd extensions/available/openvk/
```
📝We also need to import OpenVK database. Unless you use MariaDB (we are using Percona here) you should edit `install/init-static-db.sql`:
1\. Replace `utf8mb4_unicode_nopad_ci` with `utf8mb4_unicode_520_ci` everywhere.
🖥Now database dump can be imported:
```bash
mysql -p'DATABASE_PASSWORD' openvk < install/init-static-db.sql
```
🖥Also import event database:
```bash
mysql -p'DATABASE_PASSWORD' openvk_eventdb < install/init-event-db.sql
```
### Webserver configuration
Apache is already installed so we will use it.
🖥Make the user `apache` owner of the `chandler` folder:
```bash
cd /opt
chown -R apache: chandler/
```
📝Now let's create config file `/etc/httpd/conf.d/10-openvk.conf`:
```apache
<VirtualHost *:80>
ServerName openvk.local
DocumentRoot /opt/chandler/htdocs
<Directory /opt/chandler/htdocs>
AllowOverride All
Require all granted
</Directory>
ErrorLog /var/log/openvk/error.log
CustomLog /var/log/openvk/access.log combinedio
</VirtualHost>
```
📝Also enable rewrite_module by creating `/etc/httpd/conf.modules.d/02-rewrite.conf`:
```apache
LoadModule rewrite_module modules/mod_rewrite.so
```
🖥Make directory for OpenVK logs and make the user `apache` owner of it:
```bash
mkdir /var/log/openvk
chown apache: /var/log/openvk/
```
🖥Make the firewall exception for port 80:
```bash
firewall-cmd --permanent --add-port=80/tcp
firewall-cmd --reload
```
🖥And start Apache:
```bash
systemctl start httpd
```
OpenVK should work right now!
Also you can raise 2MB the file limit through editing `/etc/php.ini`. And it's also better to install PHPMyAdmin but I won't cover that.
