Editing Upgrading major versions of Nginx,Mysql

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 -l | grep nginx

•	apt-get purge nginx

After removing old nginx reboot the server


Installing NEW Nginx

•	Cd /root/nginx 1.18.0

•	make install

• Go to cd etc/

• unzip the older zipped nginx folder here

•	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 /nginx/sites-enabled

Check syntax and potential errors:

•	sudo nginx –t

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

# 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

# Available applications:

  # Nginx Full
  # Nginx HTTP
  # Nginx HTTPS
  # OpenSSH
