二、centos 安装tomcat源码包

Installing Apache Tomcat 9

We’ll have to create a system user and group before proceeding with the installation process of Tomcat so create a user and group named tomcat to run below-given command to do so:

groupadd tomcat useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat

The options used in the above command perform the following:

-s /bin/false will disable shell access -g tomcat will assign a new user to the group tomcat -d /opt/tomcat will define the home directory for the user

Downloading and Installing Apache Tomcat

First, go to the directory /opt and download Apache Tomcat server using wgetcommand from as shown below:

cd /opt/

This will change your current directory to directory /opt/

If in any case you haven’t installed wget command on your system then first of all install it using this command:

yum install wgetwget

Now extract using tar command as below :

tar -xzvf apache-tomcat-9.0.0.M15.tar.gz

Move all the files that are in the apache-tomcat-9.0.0.M15 directory to the tomcatdirectory to do so run following command :

mv apache-tomcat-9.0.0.M15/* tomcat/

Now change the proper ownership using the following command:

chown -hR tomcat:tomcat tomcat

Testing Tomcat

We recommend you to run a short testing on Tomcat to make sure that there is no error and it is installed successfully so follow the below-given process.

Run below given command :

cd /opt/tomcat/bin/ ./

Currently, Tomcat is using port number 8080 so check the open port using netstat command as shown:

netstat -plntu

You can check this using a web browser with http://yourserver_IP:8080 then you’ll see the homepage of Apache Tomcat Server but we recommend you to use browser later at final testing because we will run Tomcat with a systemd service file in the final configuration.

Now run following commands :

cd /opt/tomcat/bin/./shutdown.shchown -hR tomcat:tomcat /opt/tomcat/

Creating a systemd Service File

Now you’ll need to create a systemd service file to run Apache Tomcat as a tomcat user. Creation of a systemd service file is recommended for easy starting and stopping the service.

Run following command :

nano /etc/systemd/system/tomcat.service

Add the content below into nano text editor, you can simply copy/paste this into the file:

Description=Apache Tomcat 8 Servlet Container[Service]


Save and close the file then run the following commands to start the Tomcat service and enable Tomcat service to start on boot:

systemctl daemon-reload systemctl start tomcat systemctl enable tomcat

Once again check for the open port using netstat command shown below:

netstat -plntu

Now run the command below and make sure that service is active as shown below:

systemctl status tomcat

Configure Tomcat Users

Run following command to edit tomcat-users.xml file using any text editor here we are using nano :

cd /opt/tomcat/conf/ nano tomcat-users.xml

Create a new line under line 43 and add following content, again you can simply copy-paste this into file like you’ve done before:

<role rolename="manager-gui"/>
<user username="admin" password="password" roles="manager-gui,admin-gui"/>

Save the file and exit text editor.

Now you’ll have to edit context.xml file using following commands:

cd /opt/tomcat/webapps/manager/META-INF/nano context.xml

Now you’ll have to comment out line 19 and 20 as shown below:

   <Context antiResourceLocking="false" privileged="true" >
    <!--  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /> -->

Save the file and exit nano text editor .

Now once again edit the context.xml file but this time it is in host-manager directory so run below given commands :

cd /opt/tomcat/webapps/host-manager/META-INF/nano context.xml

Comment out again line 19 and 20.

  <Context antiResourceLocking="false" privileged="true" >
    <!--  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" /> -->

Save the file and exit nano text editor .

Now you’ll have to restart the tomcat and to do so run following command:

systemctl restart tomcat

Configure Firewalld

If in any case you haven’t installed firewalld on your system then install it first using yum command as shown below:

yum install firewalld

You’ll have to start firewalld and add it to start at boot time, to do so run following command:

systemctl start firewalldsystemctl enable firewalld

Now you’ll have to use firewall-cmd command to add apache tomcat port number 8080 to the firewall so simply enter below-given command:

firewall-cmd --zone=public --permanent --add-port=8080/tcp

You’ll see a result as “success”.

Now reload the firewall service using the following command:

firewall-cmd --reload

We recommend you to check for all service available and port 8080 is open and there is no error, to do so run following command:

firewall-cmd --list-portsfirewall-cmd --list-services
