User privileges: root or non-root user with sudo privileges<\/li>\n<\/ul>\n\n\n\nStep 1. Update the System<\/h2>\n\n\n\n Before we start with the installation of this software we will update the system packages to their latest versions available.<\/p>\n\n\n\n
sudo apt-get update -y && sudo apt-get upgrade -y<\/pre>\n\n\n\nStep 2. Install Nginx<\/h2>\n\n\n\n To install the Nginx web server execute the following command:<\/p>\n\n\n\n
sudo apt-get install nginx -y<\/pre>\n\n\n\nAfter successful installation, the Nginx service will be automatically started. To check the status of Nginx, execute the following command:<\/p>\n\n\n\n
sudo systemctl status nginx<\/pre>\n\n\n\nYou should get the following output:<\/p>\n\n\n\n
root@vps:~# sudo systemctl status nginx\n\u25cf nginx.service - A high performance web server and a reverse proxy server\n Loaded: loaded (\/lib\/systemd\/system\/nginx.service; enabled; vendor preset: enabled)\n Active: active (running) since Fri 2022-11-18 03:28:11 CST; 14min ago\n Docs: man:nginx(8)\n Process: 3778 ExecStartPre=\/usr\/sbin\/nginx -t -q -g daemon on; master_process on; (code=exited, status=0\/SUCCESS)\n Process: 3779 ExecStart=\/usr\/sbin\/nginx -g daemon on; master_process on; (code=exited, status=0\/SUCCESS)\n Main PID: 3874 (nginx)\n Tasks: 4 (limit: 4575)\n Memory: 6.0M\n CPU: 53ms\n CGroup: \/system.slice\/nginx.service\n \u251c\u25003874 \"nginx: master process \/usr\/sbin\/nginx -g daemon on; master_process on;\"\n<\/pre>\n\n\n\nStep 3. Install MongoDB Database Server<\/h2>\n\n\n\n First, add the GPG keys:<\/p>\n\n\n\n
wget -qO - https:\/\/www.mongodb.org\/static\/pgp\/server-4.4.asc | sudo apt-key add -<\/pre>\n\n\n\nThen, we need to add the MongoDB repository:<\/p>\n\n\n\n
echo \"deb [ arch=amd64,arm64 ] https:\/\/repo.mongodb.org\/apt\/ubuntu focal\/mongodb-org\/4.4 multiverse\" | sudo tee \/etc\/apt\/sources.list.d\/mongodb-org-4.4.list\n\necho \"deb http:\/\/security.ubuntu.com\/ubuntu focal-security main\" | sudo tee \/etc\/apt\/sources.list.d\/focal-security.list\n<\/pre>\n\n\n\nOnce done, update the system and install the MongoDB database server.<\/p>\n\n\n\n
sudo apt update -y\nsudo apt upgrade -y\nsudo apt-get install gnupg libssl1.1 -y\n\nsudo apt-get install mongodb-org=4.4.8 mongodb-org-server=4.4.8 mongodb-org-shell=4.4.8 mongodb-org-mongos=4.4.8 mongodb-org-tools=4.4.8 -y\n<\/pre>\n\n\n\nAfter this start and enable the MongoDB service:<\/p>\n\n\n\n
sudo systemctl start mongod && sudo systemctl enable mongod<\/pre>\n\n\n\nTo check the status of MongoDB execute the command below:<\/p>\n\n\n\n
sudo systemctl status mongod<\/pre>\n\n\n\nYou should receive the following output:<\/p>\n\n\n\n
root@vps:~# systemctl status mongod\n\u25cf mongod.service - MongoDB Database Server\n Loaded: loaded (\/lib\/systemd\/system\/mongod.service; disabled; vendor preset: enabled)\n Active: active (running) since Fri 2022-11-18 03:59:25 CST; 5s ago\n Docs: https:\/\/docs.mongodb.org\/manual\n Main PID: 8635 (mongod)\n Memory: 59.9M\n CPU: 1.036s\n CGroup: \/system.slice\/mongod.service\n \u2514\u25008635 \/usr\/bin\/mongod --config \/etc\/mongod.conf\n\nNov 18 03:59:25 host.test.vps systemd[1]: Started MongoDB Database Server.\n<\/pre>\n\n\n\nStep 4. Install Java<\/h2>\n\n\n\n To install the latest Java version, we need to install first some Java dependencies:<\/p>\n\n\n\n
apt install apt-transport-https gnupg2 uuid-runtime pwgen curl dirmngr -y<\/pre>\n\n\n\nOnce these dependencies are installed, we can install Java with the following command:<\/p>\n\n\n\n
apt install openjdk-11-jre-headless -y<\/pre>\n\n\n\nAfter successfull installation, check the installed Java version:<\/p>\n\n\n\n
java --version<\/pre>\n\n\n\nYou should receive output similar to this:<\/p>\n\n\n\n
root@host:~# java --version\nopenjdk 11.0.17 2022-10-18\nOpenJDK Runtime Environment (build 11.0.17+8-post-Ubuntu-1ubuntu222.04)\nOpenJDK 64-Bit Server VM (build 11.0.17+8-post-Ubuntu-1ubuntu222.04, mixed mode, sharing)\n<\/pre>\n\n\n\nStep 5. Install Elasticsearch<\/h2>\n\n\n\n First we are going to add the elasticsearch public key to the APT, and the elastic source to the sources.list.d<\/strong>.<\/p>\n\n\n\nTo add the GPG-KEY<\/strong> execute the following command:<\/p>\n\n\n\ncurl -fsSL https:\/\/artifacts.elastic.co\/GPG-KEY-elasticsearch | sudo gpg --dearmor -o \/usr\/share\/keyrings\/elastic.gpg<\/pre>\n\n\n\nTo add the elastic source in the sources.list.d<\/strong> execute the following command:<\/p>\n\n\n\necho \"deb [signed-by=\/usr\/share\/keyrings\/elastic.gpg] https:\/\/artifacts.elastic.co\/packages\/7.x\/apt stable main\" | sudo tee -a \/etc\/apt\/sources.list.d\/elastic-7.x.list<\/pre>\n\n\n\nNow, update the system and install the elastic search with the following commands:<\/p>\n\n\n\n
sudo apt update -y\n\nsudo apt install elasticsearch\n\n<\/pre>\n\n\n\nStart and enable the elasticsearch service.<\/p>\n\n\n\n
sudo systemctl start elasticsearch && sudo systemctl enable elasticsearch<\/pre>\n\n\n\nTo check the status of the service if is up and running execute the following command:<\/p>\n\n\n\n
sudo systemctl status elasticsearch<\/pre>\n\n\n\nYou should receive the following output:<\/p>\n\n\n\n
root@host:~# sudo systemctl status elasticsearch\n\u25cf elasticsearch.service - Elasticsearch\n Loaded: loaded (\/lib\/systemd\/system\/elasticsearch.service; enabled; vendor preset: enabled)\n Active: active (running) since Tue 2022-11-22 16:59:52 CST; 2min 8s ago\n Docs: https:\/\/www.elastic.co\n Main PID: 11001 (java)\n Tasks: 68 (limit: 4575)\n Memory: 2.3G\n CPU: 2min 36.261s\n CGroup: \/system.slice\/elasticsearch.service\n \u251c\u250011001 \/usr\/share\/elasticsearch\/jdk\/bin\/java -Xshare:auto -Des.networkaddress.cache.ttl=60 -Des.networkaddress.cache.negative.ttl=10 -XX:+AlwaysPreTouch >\n \u2514\u250011191 \/usr\/share\/elasticsearch\/modules\/x-pack-ml\/platform\/linux-x86_64\/bin\/controller\n\nNov 22 16:58:50 host.test.vps systemd[1]: Starting Elasticsearch...\n<\/pre>\n\n\n\nAfter starting the service we need to configure the cluster name for our Graylog server:<\/p>\n\n\n\n
sudo nano \/etc\/elasticsearch\/elasticsearch.yml<\/pre>\n\n\n\nEnter these lines of code:<\/p>\n\n\n\n
cluster.name: graylog\naction.auto_create_index: false<\/pre>\n\n\n\nSave the file, close it and restart the daemon along with elasticsearch service:<\/p>\n\n\n\n
sudo systemctl daemon-reload && sudo systemctl restart elasticsearch<\/pre>\n\n\n\nStep 6. Install Graylog Server<\/h2>\n\n\n\n First, we need to download the Graylog package:<\/p>\n\n\n\n
wget https:\/\/packages.graylog2.org\/repo\/packages\/graylog-4.3-repository_latest.deb<\/pre>\n\n\n\nAfter that, we need to install it:<\/p>\n\n\n\n
dpkg -i graylog-4.3-repository_latest.deb\n\nsudo apt update -y\n\nsudo apt install graylog-server -y<\/pre>\n\n\n\nStart and Enable the graylog-server service:<\/p>\n\n\n\n
systemctl enable graylog-server.service && systemctl start graylog-server.service<\/pre>\n\n\n\nTo check the status of the Graylog server execute the following command:<\/p>\n\n\n\n
systemctl status graylog-server<\/pre>\n\n\n\nYou should get output similar to this:<\/p>\n\n\n\n
\u25cf graylog-server.service - Graylog server\n Loaded: loaded (\/lib\/systemd\/system\/graylog-server.service; enabled; vendor preset: enabled)\n Active: active (running) since Tue 2022-11-22 18:03:17 CST; 199ms ago\n Docs: http:\/\/docs.graylog.org\/\n Main PID: 13451 (graylog-server)\n Tasks: 9 (limit: 4575)\n Memory: 5.5M\n CPU: 268ms\n CGroup: \/system.slice\/graylog-server.service\n \u251c\u250013451 \/bin\/sh \/usr\/share\/graylog-server\/bin\/graylog-server\n \u251c\u250013470 \/usr\/bin\/java -XX:+PrintFlagsFinal\n \u2514\u250013471 grep -q UseConcMarkSweepGC\n\nNov 22 18:03:17 host.test.vps systemd[1]: Started Graylog server.\n<\/pre>\n\n\n\nStep 7. Configure Graylog User<\/h2>\n\n\n\n In this step we will secure the user passwords using the password generator command pwgen<\/strong>.<\/p>\n\n\n\npwgen -N 1 -s 96<\/pre>\n\n\n\nYou will get output similar to this:<\/p>\n\n\n\n

systemctl daemon-reload\n\nsystemctl restart graylog-server<\/pre>\n\n\n\nStep 8. Create Nginx Virtual Host<\/h2>\n\n\n\n Create the Nginx virtual host file.<\/p>\n\n\n\n
touch \/etc\/nginx\/sites-available\/graylog.conf<\/pre>\n\n\n\nOpen the file and paste the following lines of code:<\/p>\n\n\n\n
server {\n listen 80;\n server_name <strong>YourDomainHere<\/strong>;\n\nlocation \/\n {\n proxy_set_header Host $http_host;\n proxy_set_header X-Forwarded-Host $host;\n proxy_set_header X-Forwarded-Server $host;\n proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;\n proxy_set_header X-Graylog-Server-URL http:\/\/$server_name\/;\n proxy_pass <strong>http:\/\/YourServerIPHere:9000<\/strong>;\n }\n\n}<\/pre>\n\n\n\nEnable the Nginx configuration with a symbolic link.<\/p>\n\n\n\n
ln -s \/etc\/nginx\/sites-available\/graylog.conf \/etc\/nginx\/sites-enabled\/<\/pre>\n\n\n\nCheck the Nginx syntax:<\/p>\n\n\n\n
nginx -t<\/pre>\n\n\n\nIf you get the following output, restart the Nginx service:<\/p>\n\n\n\n
root@host:~# nginx -t\nnginx: the configuration file \/etc\/nginx\/nginx.conf syntax is ok\nnginx: configuration file \/etc\/nginx\/nginx.conf test is successful<\/pre>\n\n\n\nsystemctl restart nginx<\/pre>\n\n\n\nNow, you can access your Graylog server at http:\/\/YourDomainHere.com<\/strong> using the credentials you created above.<\/p>\n\n\n\n
Once logged in, you will get the following screen:<\/p>\n\n\n
