# Installing Plume (for development or production)
|
|
|
|
## Prerequisites
|
|
|
|
In order to be installed and to work correctly, Plume needs:
|
|
|
|
- *Git* (to get the code)
|
|
- *Curl* (for RustUp, the Rust installer)
|
|
- *GCC* and *make* (to compile C dependencies)
|
|
- *PostgreSQL* (for the database)
|
|
- *GetText* (to manage translations)
|
|
- *Rust* and *Cargo* (to build the code)
|
|
- *OpenSSL* and *OpenSSL librairies* (for security)
|
|
|
|
All the following instructions will need a terminal.
|
|
|
|
Here are the commands to install PostgreSQL and GetText on various operating systems.
|
|
Some of them may need root permissions.
|
|
|
|
On **Debian**:
|
|
|
|
```bash
|
|
apt update
|
|
apt install gettext postgresql postgresql-contrib libpq-dev git curl gcc make openssl libssl-dev
|
|
```
|
|
|
|
On **Fedora**, **CentOS** or **RHEL**:
|
|
|
|
```bash
|
|
dnf install postgresql-server postgresql-contrib mariadb-devel libsq3-devel libpqxx libpqxx-devel git curl gcc make openssl openssl-devel
|
|
# TODO: GetText
|
|
```
|
|
|
|
On **Gentoo**:
|
|
|
|
```bash
|
|
emerge --sync
|
|
emerge -av postgresql eselect-postgresql
|
|
# TODO: GetText + Git install
|
|
```
|
|
|
|
On **Mac OS X**, with [Homebrew](https://brew.sh/):
|
|
|
|
```bash
|
|
brew update
|
|
brew install postgres
|
|
# TODO: GetText + Git install
|
|
```
|
|
|
|
## Creating a new user (optional)
|
|
|
|
This step is recommended if you are in a **production environment**, but it is not necessary.
|
|
|
|
```bash
|
|
adduser plume
|
|
su - plume
|
|
cd ~
|
|
```
|
|
|
|
Creating a new user will let you use systemd to manage Plume if you want (see the dedicated section below).
|
|
|
|
## Installing Rust and Cargo
|
|
|
|
We said that Plume needed Rust and Cargo to work, but we didn't installed them at the same time as PostgreSQL and GetText, because there is an universal installation method called RustUp.
|
|
|
|
You can install it on **GNU/Linux** and **Mac OS X** with:
|
|
|
|
```bash
|
|
curl https://sh.rustup.rs -sSf | sh
|
|
```
|
|
|
|
When asked, choose the *"1) Proceed with installation (default)"* option.
|
|
|
|
Then run this command to be able to run cargo in the current session:
|
|
|
|
```bash
|
|
export PATH="$PATH:/home/plume/.cargo/bin:/home/plume/.local/bin:/usr/local/sbin"
|
|
```
|
|
|
|
On **Windows**, you'll need, if you don't already have them, to download and install the [Visual C++ 2015 Build Tools](https://www.microsoft.com/en-us/download/details.aspx?id=48159). Then, download the [rustup installer](https://www.rust-lang.org/en-US/install.html) and run it.
|
|
|
|
## Getting and compiling the Plume source code
|
|
|
|
Plume needs to be compiled from source.
|
|
|
|
```bash
|
|
git clone https://github.com/Plume-org/Plume.git
|
|
cd Plume
|
|
|
|
# This may take some time as RustUp will download all
|
|
# the required Rust components, and Cargo will download
|
|
# and compile all dependencies.
|
|
cargo build
|
|
```
|
|
|
|
We may provide precompiled packages and Docker images in the future (if you have experience in these fields and want to help, you're welcome).
|
|
|
|
## Configuring PostgreSQL
|
|
|
|
You can either run PostgreSQL from the machine that runs Plume, or from another server. We recommend you to use the first setup for development environments, or in production for small instances.
|
|
|
|
In the first case, just run this command after the PostgreSQL installation, to start it:
|
|
|
|
```
|
|
service postgresql start
|
|
```
|
|
|
|
If you want to have two separate machines, run these commands on the database server after you installed the dependencies mentionned above on both servers:
|
|
|
|
```bash
|
|
service postgresql start
|
|
su - postgres
|
|
createuser -d -P plume
|
|
createdb -O plume plume
|
|
```
|
|
|
|
|
|
## Running migrations
|
|
|
|
Migrations are scripts to update the database. They are run by a tool called Diesel, which can be installed with:
|
|
|
|
```bash
|
|
cargo install diesel_cli --no-default-features --features postgres --version '=1.2.0'
|
|
```
|
|
|
|
Plume should normally run migrations for you when needed, but if you want to run them manually, the command is:
|
|
|
|
```bash
|
|
diesel migration run --database-url postgres://USER:PASSWORD@IP:PORT/plume
|
|
```
|
|
|
|
This command may be useful if you decided to use a separate database server.
|
|
|
|
## Starting Plume
|
|
|
|
When you launch Plume for the first time, it will ask you a few questions to setup your instance before it actually launches. To start it, run these commands.
|
|
|
|
```
|
|
# Optional, only do it if the database URL is not
|
|
# postgres://plume:plume@localhost/plume
|
|
export DB_URL=postgres://plume:PASSWORD@DBSERVERIP:DBPORT/plume
|
|
|
|
cargo run
|
|
```
|
|
|
|
## Configuring Nginx
|
|
|
|
Here is a sample Nginx configuration for a Plume instance (replace `blog.example.com` with your domain name):
|
|
|
|
```nginx
|
|
server {
|
|
listen 80;
|
|
server_name blog.example.com;
|
|
|
|
location /.well-known/acme-challenge {}
|
|
location / {
|
|
return 301 https://$host$request_uri;
|
|
}
|
|
}
|
|
|
|
server {
|
|
server_name blog.example.org;
|
|
access_log /var/log/nginx/access.log;
|
|
|
|
listen [::]:443 ssl; # managed by Certbot
|
|
SSLCertificateFile /etc/letsencrypt/live/blog.example.com/cert.pem
|
|
SSLCertificateKeyFile /etc/letsencrypt/live/blog.example.com/privkey.pem

|
|

|
|
```
|
|
|
|
## Configuring Apache
|
|
|
|
If you prefer Apache, you can use this configuration (here too replace `blog.example.com` with your domain):
|
|
|
|
```apache
|
|
<VirtualHost *:80>
|
|
ServerName blog.example.com
|
|
Redirect / https://blog.example.com/
|
|
</VirtualHost>
|
|
|
|
<VirtualHost *:443>
|
|
ServerAdmin admin@example.com
|
|
ServerName blog.example.com
|
|
|
|
Header always set Referrer-Policy "strict-origin-when-cross-origin"
|
|
Header always set Strict-Transport-Security "max-age=31536000"
|
|
SSLEngine on
|
|
|
|
# for cipher conf: https://cipherli.st/
|
|
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH
|
|
SSLProtocol All -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
|
|
SSLHonorCipherOrder On
|
|
Header always set Strict-Transport-Security "max-age=63072000; includeSubDomains; preload"
|
|
Header always set X-Frame-Options DENY
|
|
Header always set X-Content-Type-Options nosniff
|
|
SSLCompression off
|
|
SSLUseStapling on
|
|
SSLStaplingCache "shmcb:logs/stapling-cache(150000)"
|
|
|
|
# Requires Apache >= 2.4.11
|
|
SSLSessionTickets Off
|
|
|
|
SSLCertificateFile /etc/letsencrypt/live/blog.example.com/cert.pem
|
|
SSLCertificateKeyFile /etc/letsencrypt/live/blog.example.com/privkey.pem
|
|
SSLCertificateChainFile /etc/letsencrypt/live/blog.example.com/chain.pem
|
|
|
|
ProxyPreserveHost On
|
|
RequestHeader set X-Forwarded-Proto "https"
|
|
|
|
ProxyPass / http://127.0.0.1:7878/
|
|
ProxyPassReverse / http://127.0.0.1:7878/
|
|
</VirtualHost>
|
|
```
|
|
|
|
## Systemd integration
|
|
|
|
If you want to manage your Plume instance with systemd, you can use the following unit file (to be saved in `/etc/systemd/system/plume.service`):
|
|
|
|
```toml
|
|
[Unit]
|
|
Description=plume
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=plume
|
|
WorkingDirectory=/home/plume/Plume
|
|
ExecStart=/home/plume/.cargo/bin/cargo run
|
|
TimeoutSec=30
|
|
Restart=always
|
|
|
|
[Install]
|
|
WantedBy=multi-user.target
|
|
```
|
|
|
|
## SysVinit integration
|
|
|
|
This script can also be useful if you are using SysVinit.
|
|
|
|
```bash
|
|
#!/bin/sh
|
|
### BEGIN INIT INFO
|
|

|
|
|
|
## Caveats:
|
|
|
|
- Pgbouncer is not yet supported (named transactions are used).
|
|
- Rust nightly is a moving target, dependancies can break and sometimes you need to check a few versions to find the one working (run `rustup override set nightly-2018-05-15` or `rustup override set nightly-2018-05-31` in the Plume directory if you have issues during the compilation)
|
|
- Rust nightly 2018-06-28 is known to be failing to compile diesel 1.3.2
