+sudo yum install gcc-c++ flex bison yajl yajl-devel curl-devel curl GeoIP-devel doxygen zlib-devel
+sudo yum install lmdb lmdb-devel libxml2 libxml2-devel ssdeep ssdeep-devel lua lua-devel

+cd ModSecurity
+sudo git submodule init
+sudo git submodule update
+sudo ./build.sh
+sudo ./configure
+sudo make
+sudo make install
+sudo git clone --depth 1 https://github.com/SpiderLabs/ModSecurity-nginx.git
+sudo wget http://nginx.org/download/nginx-1.15.7.tar.gz
+sudo tar zxvf nginx-1.15.7.tar.gz
+cd nginx-1.15.7
+sudo ./configure --with-compat --add-dynamic-module=../ModSecurity-nginx
+sudo make modules
+sudo cp objs/ngx_http_modsecurity_module.so /etc/nginx/modules
+sudo mkdir /etc/nginx/modsec
+sudo cp ~/ModSecurity/unicode.mapping /etc/nginx/modsec/
+```
+
+Then add load_module instruction to nginx.conf in the main (top-level) context:
+
+```
+load_module modules/ngx_http_modsecurity_module.so;
+```
