Upgrading Version of Nginx

---

Login to Server (on which need to update Nginx version)

• Cd /home/neal/root/

Download the nginx source

• wget http://nginx.org/download/nginx-1.18.0.tar.gz

Unzip the downloaded file

• tar xzvf filename

• Nginx –V

Copy the configuration modules in text

Open the server with latest SSL version (demo.apoyar)

• Nginx –V

Copy the last configuration command with SSL and paste it in text document at last

Download the open SSL source

• Go to cd /usr/local/src/

• wget https://www.openssl.org/source/openssl-1.1.1i.tar.gz

• tar xzvf filename

• go to cd root/

• go to nginx folder

Paste here that configuration module which we have in text document and hit enter

NOTE: - If getting any errors, troubleshoot with the below steps as per errors coming across.

If the ./configure gives you any errors, take the following steps:

apt-get install uuid-dev

If ./configure gives you an error about psol not found

apt-get install libgd-dev in case of this error:

./configure: error: the HTTP image filter module requires the GD library.

apt-get install libgeoip-dev in case of:

./configure: error: the GeoIP module requires the GeoIP library.

install libssl-dev in case of:

./configure: error: SSL modules require the OpenSSL library.

install libpcre++-dev in case of:

./configure: error: the HTTP rewrite module requires the PCRE library.

apt-get install libxslt1-dev in case of:

./configure: error: the HTTP XSLT module requires the libxml2/libxslt

apt-get install zlib1g-dev ./configure: error: the HTTP gzip module requires the zlib library

apt-get install libpam0g-dev in case of: make gives you an error:

fatal error: security/pam_appl.h: No such file or directory

Then run below command

• make

Uninstall OLD Nginx

• Cd etc/

• tar czvf nginx

• mv nginx /root/

• dpkg – I l grep nginx

• apt-get purge nginx

After removing old nginx reboot the server

Installing NEW Nginx

• Cd /root/nginx 1.18.0

• Nginx –v

If the nginx command doesn't work, create a symlink:

• ln -s /usr/share/nginx/sbin/nginx /usr/sbin/Ln

• Nginx –V

• Go to cd etc/

• tar xzvf nginx 1.18.0

Go to Cd /nginx/sites-enabled

Check syntax and potential errors:

• sudo nginx –t

1. Will throw this error nginx: [emerg] mkdir() "/var/lib/nginx/body" failed (2: No such file or directory)

1. Just create directory

• mkdir -p /var/lib/nginx && sudo nginx –t

Create systemd unit file for NGINX:

• sudo vim /etc/systemd/system/nginx.service

Copy/paste the following content:

NOTE: The location of the PID file and the NGINX binary may be different depending on how NGINX was compiled.

[Unit]

Description=A high performance web server and a reverse proxy server After=network.target

[Service] Type=forking PIDFile=/run/nginx.pid ExecStartPre=/usr/sbin/nginx -t -q -g 'daemon on; master_process on;' ExecStart=/usr/sbin/nginx -g 'daemon on; master_process on;' ExecReload=/usr/sbin/nginx -g 'daemon on; master_process on;' -s reload ExecStop=-/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid TimeoutStopSec=5 KillMode=mixed

[Install] WantedBy=multi-user.target

Start and enable NGINX service:

• sudo systemctl start nginx.service && sudo systemctl enable nginx.service

Create UFW NGINX application profile:

• sudo vim /etc/ufw/applications.d/nginx

Copy/paste the following content:

[Nginx HTTP] title=Web Server (Nginx, HTTP) description=Small, but very powerful and efficient web server ports=80/tcp

[Nginx HTTPS] title=Web Server (Nginx, HTTPS) description=Small, but very powerful and efficient web server ports=443/tcp

[Nginx Full] title=Web Server (Nginx, HTTP + HTTPS) description=Small, but very powerful and efficient web server ports=80,443/tcp

Now, verify that UFW app profiles are created and recognized:

• sudo ufw app list

1. Available applications:

 # Nginx Full
 # Nginx HTTP
 # Nginx HTTPS
 # OpenSSH
