Installing Nginx From Source on CentOS 7

You may want a version of Nginx that is newer than available in the repositories. As of today (2019 April 30), the latest version is 1.16.0. The Nginx developers maintain a yum repository with the latest version. I recommend using the repository because it will be easier to keep Nginx up to date. The Nginx Linux packages page explains how to add their repository to your system and install Nginx from it. If you still wish to install from source, keep reading.

The process of installing Nginx from source on CentOS has relatively few steps. They are

Install a some required packages
Create an unprivileged service account
Download the Nginx source
Compile and Install Nginx
Create a SystemD unit file
Create a SystemD environment file
Test the installation
Configure Nginx
Enable Nginx to start at boot

Install Required Packages

Compiling and running Nginx 1.16.0 requires several packages from the repositories. Install them with this command:

[root@centos7 ~]# yum install \
gcc \
zlib-devel \
openssl-devel \
make \
pcre-devel \
libxml2-devel \
libxslt-devel \
libgcrypt-devel \
gd-devel \
perl-ExtUtils-Embed \
GeoIP-devel

Create an Unprivileged Service Account

Create a service account identical to the one the Nginx package in the EPEL repository creates:

[root@centos7 ~]# groupadd -g 994 nginx
[root@centos7 ~]# useradd -g 994 -u 996 -c "Nginx web server" -d /var/lib/nginx -s /sbin/nologin nginx

If you get the output below, you can safely move on. It just means Nginx is or has been installed from a repository.

[root@centos7 ~]#  groupadd -g 994 nginx
groupadd: group 'nginx' already exists
[root@centos7 ~]# useradd -g 994 -u 996 -c "Nginx web server" -d /var/lib/nginx -s /sbin/nologin nginx
useradd: user 'nginx' already exists

Download the Nginx Source

Use curl to download the Nginx source code:

[root@centos7 ~]# curl -L https://github.com/nginx/nginx/archive/release-1.16.0.tar.gz > nginx-release-1.16.0.tar.gz

Extract the source code archive with tar:

[root@centos7 ~]# tar xf nginx-release-1.16.0.tar.gz

Compile Nginx

Change your working directory to the directory created by the archive file:

[root@centos7 ~]# cd nginx-release-1.16.0

The Building Nginx from Sources page on the official website provides descriptions of the options.

Configure the compile time options:

[root@centos7 nginx-release-1.16.0]# auto/configure \
--with-pcre \
--prefix=/opt/nginx-1.16.0 \
--user=nginx \
--group=nginx \
--with-threads \
--with-file-aio \
--with-http_ssl_module \
--with-http_v2_module \
--with-http_realip_module \
--with-http_addition_module \
--with-http_xslt_module=dynamic \
--with-http_image_filter_module \
--with-http_geoip_module=dynamic \
--with-http_sub_module \
--with-http_dav_module \
--with-http_flv_module \
--with-http_mp4_module \
--with-http_gunzip_module \
--with-http_gzip_static_module \
--with-http_auth_request_module \
--with-http_random_index_module \
--with-http_secure_link_module \
--with-http_degradation_module \
--with-http_slice_module \
--with-http_stub_status_module \
--without-http_charset_module \
--with-http_perl_module \
--with-mail=dynamic \
--with-mail_ssl_module \
--with-stream=dynamic \
--with-stream_ssl_module \
--with-stream_realip_module \
--with-stream_geoip_module=dynamic \
--with-stream_ssl_preread_module

Compile and install Nginx:

[root@centos7 nginx-release-1.16.0]# make
[root@centos7 nginx-release-1.16.0]# make install

Create a SystemD Unit

If you are on a minimal system, chances are the only text editor available is vi. If this is the case and you do not want to install another editor, I wrote a short tutorial explaining the basics.

Create the unit file. Add the following to the file /etc/systemd/system/nginx-1.16.0.service:

[Unit]
Description=nginx 1.16.0
After=syslog.target network.target

[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/nginx-1.16.0
ExecStart=/opt/nginx-1.16.0/sbin/nginx $CLI_OPTIONS
ExecReload=/opt/nginx-1.16.0/sbin/nginx -s reload
ExecStop=/opt/nginx-1.16.0/sbin/nginx -s quit

[Install]
WantedBy=multi-user.target

Load the unit file into SystemD:

[root@centos7 nginx-release-1.16.0]# systemctl daemon-reload

Create an environment file for Nginx. Add the following to /etc/sysconfig/nginx-1.16.0:

# Command line options to use when starting nginx
#CLI_OPTIONS=""

Test Your Installation

Start Nginx:

[root@centos7 ~]# systemctl start nginx-1.16.0

[root@centos7 ~]# curl http://localhost | grep 'Thank you'
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   612  100   612    0     0   117k      0 --:--:-- --:--:-- --:--:--  149k
<p><em>Thank you for using nginx.</em></p>

Configure Nginx

Configuring Nginx is beyond the scope of this guide. See the official documentation for guidance.

Enable Nginx to Start at Boot

The following command will ensure Nginx starts automatically when the system boots:

[root@centos7 ~]# systemctl enable nginx-1.16.0
