Installing with CentOS 7

NGINX does not provide an NGINX http lua module for CentOS/RHEL via an RPM. This means that you need to compile NGINX and the required dependencies from source for the Lua Module from source.

1. Update and install dependencies

yum -y update
yum install -y epel-release
yum update -y
yum groupinstall -y  "Development Tools"
yum install -y wget rpmdevtools git luajit luajit-devel \
openssl-devel zlib-devel pcre-devel gcc gcc-c++ make perl-ExtUtils-Embed \
lua-json lua-devel  ca-certificates
yum remove -y nettle luarocks

2. Make a /tmp directory to work in

sudo mkdir /tmp/nginx
cd /tmp/nginx

3. Download all required source files

wget -O luajit-2.0.tar.gz
wget -O nginx_devel_kit.tar.gz

4. Unpack all source files

tar -xzf luarocks-3.5.0.tar.gz
tar -xzf nettle-3.6.tar.gz
tar -xvf luajit-2.0.tar.gz
tar -xvf nginx-1.18.0.tar.gz
tar -xvf nginx_devel_kit.tar.gz
tar -xvf nginx_lua_module.tar.gz

5. Install luarocks from source

cd /tmp/nginx/luarocks-3.5.0
make install

6. Install Nettle from source

cd /tmp/nginx/nettle-3.6
./configure --prefix=/usr --disable-static
make check
make install

7. Install LuaJIT

cd /tmp/nginx/LuaJIT-2.0.5
make install

8. Build and install NGINX with required modules

cd /tmp/nginx/nginx-1.18.0
LUAJIT_LIB=/usr/local/lib LUAJIT_INC=/usr/local/include/luajit-2.0 \
./configure \
--user=nginx                          \
--group=nginx                         \
--prefix=/etc/nginx                   \
--sbin-path=/usr/sbin/nginx           \
--conf-path=/etc/nginx/nginx.conf     \
--pid-path=/var/run/         \
--lock-path=/var/run/nginx.lock       \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module        \
--with-http_stub_status_module        \
--with-debug                          \
--with-http_ssl_module                \
--with-pcre                           \
--with-http_perl_module               \
--with-file-aio                       \
--with-http_realip_module             \
--add-module=/tmp/nginx/ngx_devel_kit-0.3.1 \
make install

9. Install PerimeterX NGINX plugin and dependencies

luarocks install luasec
luarocks install lustache
luarocks install lua-resty-core
luarocks install lua-resty-nettle
luarocks install lua-resty-upload
luarocks install luasocket
luarocks install lua-resty-http
luarocks install lua-cjson
luarocks install perimeterx-nginx-plugin

10. OPTIONAL: If you are testing in a new environment you may need to configure the following.

  • Add the user "nginx"
sudo useradd --system --home /var/cache/nginx --shell /sbin/nologin --comment "nginx user" --user-group nginx
  • Create a systemd service for NGINX
sudo vi /usr/lib/systemd/system/nginx.service
  • Paste the following into the file you just created:
Description=nginx - high performance web server

ExecStartPre=/usr/sbin/nginx -t -c /etc/nginx/nginx.conf
ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s TERM $MAINPID

  • Enable and start the NGINX service
sudo systemctl is-enabled nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service
