Install Tomcat 8.x in AWS EC2 Instance (Amazon Linux AMI)
You will find as well the configuration of Nginx and PostgreSQL. Special thanks to @caden for the contribution!
Software to install
- Java 8
- Tomcat 8.x
Check YUM Updates
sudo su
yum list installed
yum update
Install Java 8
yum install java-1.8.0
yum remove java-1.7.0-openjdk
Install Tomcat 8.x
yum install tomcat8 tomcat8-webapps tomcat8-admin-webapps tomcat8-docs-webapp
Start Tomcat Service
service tomcat8 start
Tomcat Paths
1 Edit the tomcat-users file
cd /usr/share/tomcat8
vim /usr/share/tomcat8/conf/tomcat-users.xml

<user name="admin" password="YOURPASSWORD" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />
Check Tomcat Installation
- fuser: to display the process id(PID) of every process using the specified files
fuser -v -n tcp 8080
- netstat: to list out all the network (socket) connections on a system
netstat -na | grep 8080
Set Auto Start for Tomcat Service
sudo chkconfig --list tomcat8
sudo chkconfig tomcat8 on
Install Nginx
yum install nginx
Add Nginx Domain Binding
vi /etc/nginx/conf.d/shenhe.org.conf
server {
listen 80;
listen [::]:80;
server_name shenhe.org;
root /usr/share/nginx/html;
location / {
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
proxy_pass http://localhost:8080;
}
}
You can add more bindings. It’s similar. If you just want nginx to handle static files (like images, javascript, css etc), you just do it like this:
server {
listen 80;
listen [::]:80;
server_name static.shenhe.org;
root /usr/share/nginx/html;
}
Start Nginx
service nginx start
Set Auto Star for Nginx Service
sudo chkconfig --list nginx
sudo chkconfig nginx on
Install PostgreSQL
sudo yum install postgresql postgresql-server
Initialize postgresql DB
sudo service postgresql initdb
Start PostgreSQL
sudo service postgresql start
Login in with postgres
sudo -u postgres psql
Change Password
\password postgres
Quit
\q
Enable Remote Access
sudo vi /var/lib/pgsql9/data/pg_hba.conf
Add you IP to trust IP
host all all 125.69.29.0/24 trust
Also change this line from
host all all 127.0.0.1/32 ident
To
host all all 127.0.0.1/32 md5
sudo vi /var/lib/pgsql9/data/postgresql.conf
Change
#listen_addresses = 'localhost'
To
listen_addresses = '*'
Auto Start PostgreSQL
sudo chkconfig --list postgresql
sudo chkconfig postgresql on
Add swap to EC2
sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=2048
sudo /sbin/mkswap /var/swap.1
sudo chmod 600 /var/swap.1
sudo /sbin/swapon /var/swap.1
Auto mount Swap
To enable it by default after reboot, add this line to /etc/fstab:
/var/swap.1 swap swap defaults 0 0
