### Info

**As EasyEngine v3 will no longer receive any updates, configurations available in this repository are being updated for [WordOps](https://wordops.net/) (EEv3 fork).**

All previous configurations are still available in the branch [easyengine-v3](https://github.com/VirtuBox/ubuntu-nginx-web-server/tree/easyengine-v3).

Configuration files with comments available by following the link **source**

## Initial configuration

### System update and packages cleanup

```bash
apt-get update && apt-get dist-upgrade -y && apt-get autoremove --purge -y && apt-get clean
```

### Install useful packages

```bash
sudo apt-get install haveged curl git unzip zip fail2ban htop nload nmon ntp gnupg gnupg2 wget pigz tree ccze mycli -y
```

### Clone the repository

```bash
git clone https://github.com/VirtuBox/ubuntu-nginx-web-server.git $HOME/ubuntu-nginx-web-server
```

### Updating the repository

```bash
git -C $HOME/ubuntu-nginx-web-server pull origin master
```

### Tweak Kernel & Increase open files limits

Included by default in WordOps - this may not be needed anymore

[source sysctl.conf](https://github.com/VirtuBox/ubuntu-nginx-web-server/blob/master/etc/sysctl.conf) - [limits.conf source](https://github.com/VirtuBox/ubuntu-nginx-web-server/blob/master/etc/security/limits.conf)

```bash
cp $HOME/ubuntu-nginx-web-server/etc/sysctl.d/60-ubuntu-nginx-web-server.conf /etc/sysctl.d/60-ubuntu-nginx-web-server.conf
```

Ubuntu 16.04 LTS do not support the new tcp congestion control algorithm bbr, we will use htcp instead.

```bash
# On ubuntu 18.04 LTS
modprobe tcp_bbr && echo 'tcp_bbr' >> /etc/modules-load.d/bbr.conf
echo -e '\nnet.ipv4.tcp_congestion_control = bbr\nnet.ipv4.tcp_notsent_lowat = 16384' >> /etc/sysctl.d/60-ubuntu-nginx-web-server.conf

# On ubuntu 16.04 LTS
modprobe tcp_htcp && echo 'tcp_htcp' >> /etc/modules-load.d/htcp.conf
echo 'net.ipv4.tcp_congestion_control = htcp' >> /etc/sysctl.d/60-ubuntu-nginx-web-server.conf
```

Then to apply the configuration :

```bash
sysctl -e -p /etc/sysctl.d/60-ubuntu-nginx-web-server.conf
```

Increase openfiles limits

```bash
sudo bash -c 'echo -e "* hard nofile 500000\n* soft nofile 500000\nroot hard nofile 500000\nroot soft nofile 500000\n" >> /etc/security/limits.conf'
```

### disable transparent hugepage for redis

```bash
echo never > /sys/kernel/mm/transparent_hugepage/enabled
```

--------------------------------------------------------------------------------

## WordOps Setup

### Install MariaDB 10.3

Included by default in WordOps - this may not be needed anymore

Instructions available in [VirtuBox Knowledgebase](https://kb.virtubox.net/knowledgebase/install-latest-mariadb-release-easyengine/)

```bash
bash <(wget -qO - https://downloads.mariadb.com/MariaDB/mariadb_repo_setup) --mariadb-server-version=10.3 --skip-maxscale -y
sudo apt update && sudo apt install mariadb-server -y
```

Secure MariaDB after install by running the command :

```bash
mysql_secure_installation
```

### MySQL Tuning

You can download my example of my.cnf, optimized for VPS with 4GB RAM. [my.cnf source](https://github.com/VirtuBox/ubuntu-nginx-web-server/blob/master/etc/mysql/my.cnf)

```bash
cp -f $HOME/ubuntu-nginx-web-server/etc/mysql/my.cnf /etc/mysql/my.cnf
```

It include modification of innodb_log_file_size variable, so you need to use the following commands to apply the new configuration :

```bash
sudo service mysql stop

sudo mv /var/lib/mysql/ib_logfile0 /var/lib/mysql/ib_logfile0.bak
sudo mv /var/lib/mysql/ib_logfile1 /var/lib/mysql/ib_logfile1.bak

sudo service mysql start
```

### Increase MariaDB open files limits

```bash
echo -e '[Service]\nLimitNOFILE=500000' > /etc/systemd/system/mariadb.service.d/limits.conf

sudo systemctl daemon-reload
sudo systemctl restart mariadb
```

### Setup cronjob to optimize your MySQL databases and repair them if needed

Open the crontab editor

```bash
sudo crontab -e
```

Then add the following cronjob

```cronjob
@weekly /usr/bin/mysqlcheck -Aos --auto-repair > /dev/null 2>&1
```

## Install WordOps

```bash
# noninteractive install - you can replace $USER with your username & root@$HOSTNAME by your email
sudo bash -c 'echo -e "[user]\n\tname = $USER\n\temail = root@$HOSTNAME" > $HOME/.gitconfig'

wget -qO wo wops.cc && sudo bash wo
```

### enable wo bash_completion

```bash
source /etc/bash_completion.d/wo_auto.rc
```

### Install Nginx, php7.2, php7.3, and configure WO backend

```bash
wo stack install
wo stack install --php73
```

### Set your email instead of root@localhost

```bash
echo 'root: [email protected]' >> /etc/aliases
newaliases
```

### Install Composer - Fix phpmyadmin install issue

Included by default in WordOps - this may not be needed anymore

```bash
cd ~/ ||exit
curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/bin/composer

chown www-data:www-data /var/www
sudo -u www-data -H composer update -d /var/www/22222/htdocs/db/pma/
```

### Allow shell for www-data for SFTP usage

```bash
usermod -s /bin/bash www-data
```

## Install PHP

This section has been removed because WordOps already install PHP 7.2 & PHP 7.3 by default

### Set the proper alternative for /usr/bin/php

If you want to choose which version of php to use with the command `php`, you can use the command `update-alternatives`

```bash
# php5.6
sudo update-alternatives --install /usr/bin/php php /usr/bin/php5.6 80

# php7.0
sudo update-alternatives --install /usr/bin/php php /usr/bin/php7.0 80

# php7.1
sudo update-alternatives --install /usr/bin/php php /usr/bin/php7.1 80

# php7.2
sudo update-alternatives --install /usr/bin/php php /usr/bin/php7.2 80

# php7.3
sudo update-alternatives --install /usr/bin/php php /usr/bin/php7.3 80
```

Then you can check php version with command `php -v`

## NGINX Configuration

### Additional Nginx configuration (/etc/nginx/conf.d)

Included by default in WordOps - this may not be needed anymore

- stub_status configuration on 127.0.0.1:80 : stub_status.conf
- restore visitor real IP under Cloudflare : cloudflare.conf

```bash
# copy all common nginx configurations
cp -rf $HOME/ubuntu-nginx-web-server/etc/nginx/conf.d/* /etc/nginx/conf.d/

# commit change with git
[ ! -d /etc/nginx/.git ] && { git -C /etc/nginx init; } git -C /etc/nginx/ add . && git -C /etc/nginx/ commit -m "update conf.d configurations"

```

### Compile the latest Nginx release with [nginx-ee](https://github.com/VirtuBox/nginx-ee)

```bash
bash <(wget -O - virtubox.net/nginx-ee || curl -sL virtubox.net/nginx-ee)
```
