The post LEMP: CentOS 7, NGINX, PHP7, and Redis for WordPress appeared first on Justin Silver.
]]>The post Node.js + PM2 + NGINX + Redis on CentOS 7 appeared first on Justin Silver.
]]>This is a quick setup guide for the application stack I have been using recently. Most of my latest work has been a throwback to the first server-side programming I did in the 90’s – javascript – except this time it’s Node.js instead of Netscape Communication Server. In this setup PM2 is used to manage the Node process running as an arbitrary user, running on an unprivileged port. This means that the application can be restarted without root credentials. The front-end is served by NGINX and it does need to be started as root because it runs on the privileged ports 80 and 443 in this use case. It also gives us a lot of the built in features that Nginx gives you on the front end, like serving all your content over SSL – for free using Let’s Encrypt event. My caching needs are provided by Redis.
Here is the setup – run as root or use sudo.
Enable the firewalld service and only allow http/s traffic to the server – in addition to the default of just ssh.
#!/bin/bash # enable on book systemctl enable firewalld # (re)start the service (service firewalld status > /dev/null && service firewalld restart) || service firewalld start # add the http and http services and reload firewall-cmd --permanent --zone=public --add-service=http firewall-cmd --permanent --zone=public --add-service=https firewall-cmd --reload
Use Letsencrypt for free SSL certificates.
yum -y install letsencrypt openssl dhparam -out /etc/ssl/certs/dhparam.pem 2048

We are going to use the “mainline” repo to get HTTP2 support. I like to create a conf file in “sites-available” that is linked to “sites-enabled” so I can disable things easily – this is enabled by adding a file under /etc/nginx/conf.d

To install Redis with yum, first you need to install EPEL. Once the installed, you will have access to the repository containing the Redis install.
#!/bin/bash # install the EPEL repo to access Redis yum install -y epel-release yum install -y redis # fix redis background saves on low memory sysctl vm.overcommit_memory=1 && cat <<SYSCTL_MEM > /etc/sysctl.d/88-vm.overcommit_memory.conf vm.overcommit_memory = 1 SYSCTL_MEM # increase max connections sysctl -w net.core.somaxconn=65535 && cat <<SYSCTL_CONN > /etc/sysctl.d/88-net.core.somaxconn.conf net.core.somaxconn = 65535 SYSCTL_CONN sysctl -w fs.file-max=100000 && cat <<SYSCTL_FILEMAX > /etc/sysctl.d/88-fs.file-max.conf fs.file-max = 100000 SYSCTL_FILEMAX sed -i "s|^tcp-backlog [[:digit:]]\+|tcp-backlog 65535|" /etc/redis.conf # enable redis service on reboot systemctl enable redis # start service (service redis status > /dev/null && service redis restart) || service redis start
We want to install Node.js and then the PM2 package globally so that it can be accessed by other users.
#!/bin/bash # make sure the SRC_NODE_VERSION is set if [[ -z $SRC_NODE_VERSION ]]; then echo "You must specify a node version using \$SRC_NODE_VERSION"; else # Select node version to install curl --silent --location https://rpm.nodesource.com/setup_$SRC_NODE_VERSION.x | bash - # install via yum yum install -y git gcc-c++ make nodejs fi # PM2 - install as global npm install pm2@latest -g
As root, create a new user named “appuser”, or whatever you want your app user to be named. This could even be the default centos@/ec2-user@/etc that many hosts provide.
adduser appuser passwd appuser
Log in as the “appuser” user and create the Node app in your home directory. This directory should be owned by the “appuser”. In this case we assume the server is going to be listening on localhost port 3000, which means we can manage it with pm2 without having root permissions.
mkdir ~/apps cd /apps # create your app here, git clone, whatever # we assume the app is in ~/apps/myapp/server.js pm2 start ~/apps/myapp/server.js --name=myapp pm2 status myapp pm2 restart myapp
