summary

centos

https://www.phusionpassenger.com/library/install/nginx/install/oss/el7/

if ! rpm -q epel-release; then sudo yum install -y yum-utils \
http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm; fi
sudo yum-config-manager --enable epel

# Install various prerequisites
sudo yum install -y pygpgme curl

# Add our el7 YUM repository
sudo curl --fail -sSLo /etc/yum.repos.d/passenger.repo https://oss-binaries.phusionpassenger.com/yum/definitions/el-passenger.repo

# Install Passenger Nginx
# gemからinstallする方法もあるが、いいかこれで
sudo yum install -y nginx passenger

debian

あんまりおすすめしない。もろもろエラーがでる centosが安定感がある

# prepare
sudo apt-get update
sudo apt-get install -y curl gnupg build-essential
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get -y install curl-devel
sudo apt-get -y install wget
# Optional in case PCRE fails to download or if you get "The PCRE checksum could not be verified" during following passenger installation.
# sudo apt-get -y install pcre-devel

次はrvm

ruby by rvm

• One thing you should be aware of when using RVM, is that you should use rvmsudo instead of sudo when executing Ruby-related commands. This is because RVM works by manipulating environment variables. However, sudo nukes all environment variables for security reasons, which intereferes with RVM.
• rvmを使うときには ruby関連commandは sudoの代わりにrvmsudoを使うこと

# install rvm
sudo gpg2 --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
curl -sSL https://get.rvm.io | sudo bash -s stable
sudo usermod -a -G rvm `whoami`

# On systems where sudo is configured with secure_path, the shell environment needs to be modified to set rvmsudo_secure_path=1. secure_path is set on most Linux systems, but not on OS X. The following command tries to autodetect whether it is necessary to install rvmsudo_secure_path=1, and only installs the environment variable if it is the code.
if sudo grep -q secure_path /etc/sudoers; then sudo sh -c "echo export rvmsudo_secure_path=1 >> /etc/profile.d/rvm_secure_path.sh" && echo Environment variable installed; fi

# install ruby
rvmsudo rvm install 2.2.5

# install bundler
gem install bundler --no-rdoc --no-ri

passenger

passenger fundamental concepts

enable the Passenger Nginx module and restart Nginx

/etc/nginx/conf.d/passenger.conf

passenger_root /usr/share/ruby/vendor_ruby/phusion_passenger/locations.ini;
#passenger_ruby /usr/bin/ruby;
passenger_ruby /usr/local/rvm/rubies/ruby-2.2.5/bin/ruby;
passenger_instance_registry_dir /var/run/passenger-instreg;

restart nginx

sudo service nginx restart

check installation

sudo /usr/bin/passenger-config validate-install

passengerのprocess確認

sudo /usr/sbin/passenger-memory-stats

passengerのmemory

1025mがいいみたい

sudo dd if=/dev/zero of=/swap bs=1M count=1024
sudo mkswap /swap
sudo swapon /swap

setting

http {
    ...
    passenger_root /home/appuser/.rvm/gems/ruby-2.2.5/gems/passenger-5.0.29;
    passenger_ruby /home/appuser/.rvm/gems/ruby-2.2.5/wrappers/ruby;
    ...
}

node by nvm

# install nvm
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.31.2/install.sh | bash

# install 確認
# which nvmが聞かないことに注意
command -v nvm

postgresql install

mongodb install

rails app deploy

create user

sudo adduser appuser

ensure that user has SSH key

sudo mkdir -p ~appuser/.ssh
touch $HOME/.ssh/authorized_keys
sudo sh -c "cat $HOME/.ssh/authorized_keys >> ~appuser/.ssh/authorized_keys"
sudo chown -R appuser: ~appuser/.ssh
sudo chmod 700 ~appuser/.ssh
sudo sh -c "chmod 600 ~appuser/.ssh/*"

appを配置する場所をきめる

/var/www/APP_NAMEがいい

sudo mkdir -p /var/www/myapp
sudo chown myappuser: /var/www/myapp

capistrano

bundle exec cap install STAGES=staging,production
