搭建manageIQ开发环境（1）

最近在研究搭建manageIQ的开发环境，先粘贴官网上的搭建过程：

Developer Setup

Install System Packages

Fedora / CentOS 7

• CentOS only - use yum instead of dnf.

• Install Packages

  sudo dnf -y group install "C Development Tools and Libraries"  # For unf Gem and noi4r Gem
  sudo dnf -y install git-all                                    # Git and components
  sudo dnf -y install memcached                                  # Memcached for the session store
  sudo dnf -y install postgresql-devel postgresql-server         # PostgreSQL Database server and to build 'pg' Gem
  sudo dnf -y install bzip2 libffi-devel readline-devel          # For rbenv install 2.3.1 (might not be needed with other Ruby setups)
  sudo dnf -y install libxml2-devel libxslt-devel patch          # For Nokogiri Gem
  sudo dnf -y install sqlite-devel                               # For sqlite3 Gem
  sudo dnf -y install nodejs                                     # For ExecJS Gem, bower, npm, yarn, webpack.. - needs at least 6.0.0
  sudo dnf -y install libcurl-devel                              # For Curb
  rpm -q --whatprovides npm || sudo dnf -y install npm           # For CentOS 7, Fedora 23 and older
  sudo dnf -y install openssl-devel                              # For rubygems
  sudo dnf -y install cmake                                      # For rugged Gem
  sudo dnf -y install openscap                                   # Optional, for openscap Gem for container SSA
  

• Enable Memcached

  sudo systemctl enable memcached
  sudo systemctl start memcached
  

• Configure PostgreSQL

  • Required PostgreSQL version is 9.4, 9.5
    • See here how to installit in Linux distributions like CentOS 7, using SoftwareCollections.org.
    • Or follow the directions hereto install it from the PostgreSQL Global Development Group repositories.

  sudo postgresql-setup initdb
  sudo grep -q '^local\s' /var/lib/pgsql/data/pg_hba.conf || echo "local all all trust" | sudo tee -a /var/lib/pgsql/data/pg_hba.conf
  sudo sed -i.bak 's/\(^local\s*\w*\s*\w*\s*\)\(peer$\)/\1trust/' /var/lib/pgsql/data/pg_hba.conf
  sudo systemctl enable postgresql
  sudo systemctl start postgresql
  sudo -u postgres psql -c "CREATE ROLE root SUPERUSER LOGIN PASSWORD 'smartvm'"
  # This command can return with a "could not change directory to" error, but you can ignore it
  

Ubuntu / Debian

• Install Packages

  sudo apt install git                              # Git and components
  sudo apt install memcached                        # Memcached for the session store
  sudo apt install postgresql libpq-dev             # PostgreSQL Database server and to build 'pg' Gem
  sudo apt install bzip2 libffi-dev libreadline-dev # For rbenv install 2.3.1 (might not be needed with other Ruby setups)
  sudo apt install libxml2-dev libxslt-dev patch    # For Nokogiri Gem
  sudo apt install libsqlite-dev libsqlite3-dev     # For sqlite3 Gem
  sudo apt install nodejs nodejs-legacy npm         # For ExecJS Gem, bower, npm, yarn, webpack.. - needs at least 6.0.0
  sudo apt install g++                              # For unf Gem
  sudo apt install libcurl4-gnutls-dev              # For Curb
  sudo apt install cmake                            # For rugged Gem
  sudo apt install libgit2-dev pkg-config libtool
  sudo apt install libssl-dev                       # for puma < 3.7.0
  

  If your node version is less than 6.0 (debian currently has 4), you can either install it from the experimental repo:

  echo 'deb http://ftp.debian.org/debian/ experimental main non-free contrib' | sudo tee /etc/apt/sources.list.d/experimental.list
  sudo apt update
  sudo apt install nodejs nodejs-legacy npm
  

  Alternatively, you can use nvm to install a node version locally (similar to rbenv).

• Ubuntu fix for failing Bundler

  sudo apt remove libssl-dev
  wget http://ftp.cz.debian.org/debian/pool/main/o/openssl1.0/libssl1.0-dev_1.0.2l-2_amd64.deb
  wget http://ftp.cz.debian.org/debian/pool/main/o/openssl1.0/libssl1.0.2_1.0.2l-2_amd64.deb
  sudo dpkg -i libssl1.0-dev_1.0.2l-2_amd64.deb libssl1.0.2_1.0.2l-2_amd64.deb
  

• Enable Memcached

  sudo systemctl enable memcached
  sudo systemctl start memcached
  

• Configure PostgreSQL

  sudo grep -q '^local\s' /etc/postgresql/9.5/main/pg_hba.conf || echo "local all all trust" | sudo tee -a /etc/postgresql/9.5/main/pg_hba.conf
  sudo sed -i.bak 's/\(^local\s*\w*\s*\w*\s*\)\(peer$\)/\1trust/' /etc/postgresql/9.5/main/pg_hba.conf
  sudo systemctl restart postgresql
  sudo su postgres -c "psql -c \"CREATE ROLE root SUPERUSER LOGIN PASSWORD 'smartvm'\""
  

Mac

• Install Homebrew

  If you do not have Homebrew installed, go to the Homebrew website and install it.

• Install Packages

  brew install git
  brew install pkg-config
  brew install memcached
  brew install postgresql
  brew install cmake
  brew install node
  brew install yarn
  

  If your node version is less than 6, you may need to brew upgrade node and brew link node.

• Configure and start PostgreSQL
  • Required PostgreSQL version is 9.4, 9.5

  # Enable PostgreSQL on boot
  mkdir -p ~/Library/LaunchAgents
  ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
  launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
  # Create the ManageIQ superuser
  psql -d postgres -c "CREATE ROLE root SUPERUSER LOGIN PASSWORD 'smartvm'"
  

• Start memcached

  # Enable Memcached on boot
  ln -sfv /usr/local/opt/memcached/homebrew.mxcl.memcached.plist ~/Library/LaunchAgents
  launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.memcached.plist
  

Install Ruby and Bundler

• Use a Ruby version manager (choose one)
  • chruby and ruby-install
  • rvm
  • rbenv
• Required Minimum Ruby version is 2.3.1+
• Required Minimum Bundler version is 1.8.7+

Setup Git and Github

• The most reliable authentication mechanism for git uses SSH keys.
  • SSH Key Setup Set up a SSH keypair for authentication. Note: If you enter a passphrase, you will be prompted every time you authenticate with it.
• Github account setup Account Settings.
  • Profile: Fill in your personal information, such as your name.
  • Profile: Optionally set up an avatar at gravatar.com. When you set up your gravatar, be sure to have an entry for the addresses you plan to use with git / Github.
  • Emails: Enter your e-mail address and verify it, click the Verify button and follow the instructions.
  • Notification Center / Notification Email / Custom Routing: Change the email address associated with ManageIQ if desired.
  • If you are a member of the ManageIQ organization:
    • Go to the Members page.
      • Verify you are listed.
      • Optionally click Publicize Membership.
• Fork ManageIQ/manageiq:
  • Go to ManageIQ/manageiq
  • Click the Fork button and choose “Fork to ”

• Git configuration and default settings.

  git config --global user.name "Joe Smith"
  git config --global user.email [email protected]
  git config --global --bool pull.rebase true
  git config --global push.default simple
  

  If you need to use git with other email addresses, you can set the local user.email from within the clone using:

  git config user.name "Joe Smith"
  git config user.email [email protected]
  

Clone the Code

git clone [email protected]:JoeSmith/manageiq.git # Use "-o my_fork" if you don't want the remote to be named origin
cd manageiq
git remote add upstream [email protected]:ManageIQ/manageiq.git
git fetch upstream

You can add other remotes at any time to collaborate with others by running:

git remote add other_user [email protected]:OtherUser/manageiq.git
git fetch other_user

Javascripty things

Make sure your node version is at least 6.0.0. If not, you can use nvm to install a node version locally (similar to rbenv).

Note: you may need to run the npm install -g commands using sudo if you get permission errors, but if your node environment is up to date you should be able to install without sudo. If you do get these errors and you don’t want to use sudo, you can configure npm to install packages globally for a given user.

• Install the Bower package manager

  npm install -g bower
  

• Install the Yarn package manager

  Follow official instructions or

  npm install -g yarn
  

• Install the Gulp and Webpack build system

  npm install -g gulp-cli
  npm install -g webpack
  

Get the Rails environment up and running

bin/setup                  # Installs dependencies, config, prepares database, etc
bundle exec rake evm:start # Starts the ManageIQ EVM Application in the background

• You can now access the application at http://localhost:3000. The default username is admin with password smartvm.
• There is also a minimal mode available to start the application with fewer services and workers for faster startup ortargeted end-user testing. See the minimal mode guide for details.
• As an alternative to minimal mode, individual workers can also be started using Foreman
  • See the Foreman guide for details.
• To run the test suites, see the guide on that topic.

Update dependencies and migrate db

• You can update ruby and javascript dependencies as well as run migrations using one command

bin/update                # Updates dependencies using bundler and bower, runs migrations, prepares test db.

For provider, UI or other plugin development, see the guide on that topic.

Some troubleshooting notes

• First login fails

Make sure you have memcached running. If not stop the server with bundle exec rake evm:stop,start memcached and retry.

• bin/setup fails while trying to load the gem ‘sprockets/es6’

If this happens check the log forExecJS::RuntimeUnavailable: Could not find a JavaScript runtime a few lines down.When this message is present, then the you need to install node.js and re-try

• bin/setup fails while trying to install the ‘nokogiri’ gem

If this happens, you may be missing developer tools in your OS X. Try to install them withxcode-select --install and re-try.

• bin/setup fails to install the ‘sys-proctable’ gem, or installs the wrong version.

If this happens it may be a Bundler issue. Try running bundle config specific_platform trueand re-try.

• Can’t install any gems during bundle install

# install all dependencies to a local path
bundle install --path vendor/bundle

• Can’t install nokogiri-1.7.2 on a Mac

# install dependencies
brew install pkgconfig
brew install libxml2

# test the gem can be compiled with the right libxml2
export PKG_CONFIG_PATH=/usr/local/opt/libxml2/lib/pkgconfig
gem install nokogiri -v 1.7.2 -- --use-system-libraries

# configure bundle to do so
bundle config build.nokogiri --use-system-libraries --with-xml2-include=$(brew --prefix libxml2)/include/libxml2

• Can’t install sys-proctable on a Mac - a package missing even after bundle install succeeded

bundle config specific_platform true
bundle install

• If everything is hosed after an OSX upgrade

Install xcode developer tools

xcode-select --install

Uninstall existing ruby version with your version managerReinstall rubies with version manager
