I tried SonarQube locally.
Overview There are two servers. SonarQube and SonaScanner In this example, run SonarScanner with by CLI. The scan data will send to SonarQube. Getting started SonarQube (Docker) Run SonarQube on Docker:
docker run -d --name sonarqube -p 9000:9000 sonarqube:8.9-community After that,
Browse http://localhost:9000 Log in with admin/admin, and update your password Add a project, and get token. Project key: mytest Display name: MyTest Name of token: myToken Token (in my case): df19e6fee8433d746e65e0043976043fe059aa57 SonarScanner (Docker) Note the network of the SonarQube Docker container:

Install GitLab running on Docker Here is the official document. I followed it.
Caution: I’m using my GitLab on VM, not Docker image. Because the official image doesn’t contain e-mail client, and it is a little bit hard to understand. For me, deploying it on premise or VM is easy.
Install docker apt install -y docker.io Set path export GITLAB_HOME=/srv/gitlab Configurations and repositories would be stored in this path.
Run a container sudo docker run --detach \ --hostname {{ your_hostname }} \ --publish 443:443 --publish 80:80 --publish 2222:22 \ --name gitlab \ --restart always \ --volume $GITLAB_HOME/config:/etc/gitlab \ --volume $GITLAB_HOME/logs:/var/log/gitlab \ --volume $GITLAB_HOME/data:/var/opt/gitlab \ gitlab/gitlab-ce:latest I changed git port to 2222 because the server should be access by ssh.
Install Solr Install environment Ubuntu 20.04 Pre-installation Linux settings Create an user solr.
sudo useradd -r -s /bin/bash solr Change several kernel parameters in /etc/security/limits.conf.
solr hard nofile 65535 solr soft nofile 65535 solr hard nproc 65535 solr soft nproc 65535 Turn off swaps.
sudo swapoff -a Relogin so that the change will takes a place.
Install Java Install Java.
sudo apt install -y openjdk-11-jdk Install ZooKeeper Install Apache ZooKeeper.
What is ZooKeeper (very rough) Apache ZooKeeper storage hierarchal structure. Refer to ZNode.
https://de.slideshare.net/sauravhaloi/introduction-to-apache-zookeeper
Install ZooKeeper My environment Ubuntu 20.04 Pre-installation Install java first.
sudo apt update sudo apt upgrade -y sudo apt install -y openjdk-11-jdk Crete ZooKeeper user.
sudo useradd -r -s /bin/bash zk Install ZooKeeper on nodes Download link https://zookeeper.apache.org/releases.html
sudo su cd /opt curl https://mirror.netcologne.de/apache.org/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.2-bin.tar.gz -O tar xvf apache-zookeeper-3.6.2-bin.tar.gz mkdir /var/lib/zookeeper cd apache-zookeeper-3.6.2-bin cp conf/zoo_sample.cfg conf/zoo.cfg Edit conf/zoo.
What’s lsyncd My understanding is, it’s kind of rsync daemon.
Install On Ubuntu Install on source servers (no need to install on destination servers).
apt update apt install lsyncd Set kernel parameter fs.inotify.max_user_watches.
/etc/sysctl.conf
# for lsyncd fs.inotify.max_user_watches = 8192000 Before running We should configure firewall so that the source server can SSH to destination servers.
Here is my ssh snippets.
Use (sync) Configuration Here is the configuration example.
mkdir /etc/lsyncd vim /etc/lsyncd/lsyncd.
Install jellybeans I use a color scheme called “Jellybeans”.
mkdir ~/.vim cd ~/.vim sudo yum install -y git git clone https://github.com/nanotech/jellybeans.vim mkdir colors mv jellybeans.vim/colors/jellybeans.vim ~/.vim/colors/jellybeans.vim vim ~/.vimrc colorscheme jellybeans set expandtab set tabstop=2 set softtabstop=2 set shiftwidth=2 set number syntax on set t_Co=256 set foldmethod=syntax Add the line into ~/.bashrc,
TERM=xterm-256color vim plugin manager https://github.com/junegunn/vim-plug/wiki/tips#automatic-installation
Add the following in .vimrc:
let data_dir = has('nvim') ? stdpath('data') . '/site' : '~/.
Vivaldi (or Chromium or Chrome) setting Go to Preferences -> Search.
Sample I use Lexico often to search the meaning of words (as dictionary).
Name: Lexico Nickname: lex URL: https://www.lexico.com/en/definition/%s Check the Use POST method With this configuration, I can search the word, for example, “test” by type “lex test” in the browser’s URL box.
