Install Apache HTTP Server and Wildfly (JBossAS) on Oracle Linux 8 on an OCI instance.
yum install -y java-1.8.0-openjdk.x86_64
groupadd -r wildfly useradd -r -g wildfly -d /opt/wildfly -s /sbin/nologin wildfly
The URL to wget is as you like.
cd /opt wget https://download.jboss.org/wildfly/20.0.1.Final/wildfly-20.0.1.Final.zip unzip -q wildfly-20.0.1.Final.zip ln -s wildfly-20.0.1.Final wildfly
sh /opt/wildfly/bin/standalone.sh 2020-09-15 09:47:48,958 INFO [org.jboss.as](Controller Boot Thread) WFLYSRV0025: WildFly Full 20.0.1.Final (WildFly Core 12.0.3.Final) started in 13956ms - Started 314 of 580 services (370 services are lazy, passive or on-demand)
It seems that it started up safely. Press Ctrl + C to stop.
Since the script for starting the daemon is already prepared, you can start the daemon immediately by placing it.
mkdir -p /etc/wildfly cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.conf /etc/wildfly/ vi /etc/wildfly/wildfly.conf
Edit the definition as necessary. I changed the bind address to
cp /opt/wildfly/docs/contrib/scripts/systemd/launch.sh /opt/wildfly/bin/ chmod 744 /opt/wildfly/bin/launch.sh cp /opt/wildfly/docs/contrib/scripts/systemd/wildfly.service /etc/systemd/system/ chown -R wildfly /opt/wildfly*
systemctl daemon-reload systemctl start wildfly systemctl enable wildfly
You need to configure the admin user to tweak the Wildfly settings from the admin console.
cd /opt/wildfly/bin ./add-user.sh
I will omit the details, but please add the Management User according to the prompt. For more information, go to Official Documentation.
yum install -y httpd
If you keep the default settings, there is a security risk, so correct it.
Eliminate unnecessary content such as welcome pages that are not normally published as much as possible.
cd /etc/httpd/conf.d mv welcome.conf welcome.conf.org mv autoindex.conf autoindex.conf.org
vi /etc/httpd/conf/httpd.conf #Options Indexes FollowSymLinks Options FollowSymLinks
Disable the TRACE method as an XST countermeasure.
vi /etc/httpd/conf/httpd.conf #Added to the end of the file TraceEnable off
Do not include the web server version in the HTTP response header.
vi /etc/httpd/conf/httpd.conf #Added to the end of the file ServerTokens ProductOnly ServerSignature off
As a countermeasure against clickjacking, add the X-Frame-Options header to the HTTP response header.
#Create a new file vi /etc/httpd/conf.modules.d/headers.conf #Added to the end of the file Header append X-FRAME-OPTIONS SAMEORIGIN
Brings requests to Apache HTTP Server to Wildfly.
Direct access to port 80 to port 8080 (Wildfly's HTTP listener).
#Add new file vi /etc/httpd/conf.modules.d/wildfly.conf <VirtualHost *:80> ProxyPass / http://127.0.0.1:8080/ ProxyPassReverse / http://example.net/ </VirtualHost>
Once this is done, test the definition file and restart Apache HTTP Server.
httpd -t systemctl restart httpd
Simply access port 80, like http \ //example.com, and you'll be successful if you see the Wildfly welcome page.
LB of OCI supports SSL, and I tried to build backend communication with HTTP. If you try to use SSL on the Web / AP server, it will be complicated, so it is nice to be able to terminate with LB.
