Introduction to jsvc

In production, tomcat should run in daemon mode, and if you need to start tomcat as an ordinary user, you cannot use ports less than 1024, which is the limitation of the Liunx system. Only root users can use ports less than 1024. So how do you configure tomcat as a service? We can easily encapsulate our own startup script through jsvc, and we can also make tomcat run users and groups at will, and we can also specify jvm running parameters such as memory control, language, character encoding. We can also specify that tomcat starts yes pidfile. In short, we can have finer control over how tomcat works. It has an incomparable advantage over the original script.

Okay! After blowing so much, this article just wants to operate how to use ordinary users to run, the rest I haven't learned yet!

Set the permissions of the Tomcat directory

Create tomcat users (also create tomcat groups by default)

Useradd tomcat

Set the primary user of the tomcat directory to tomcat and the subordinate group to the tomcat group

Chown-R tomcat:tomcat / usr/local/tomcat/enter description here

The tomcat root permission displayed at this time actually means that the soft link belongs to root. The tomcat directory we linked already belongs to tomcat and-R recursively passes the permission.

Open the readable permissions of all files under the tomcat to the users in the group to avoid starting the Times error. For example, cannot read sever.xml file

Chmod-R galler tomcat/

Open the writable permissions of the webapps,logs,work,temp directory under tomcat to the users in the group

Chmod-R Grouw logs/ temp/ webapps/ work/

Install jsvc

I talked about deploying a Java+Tomcat environment last time, and this article is a follow-up to the last time.

Attached is the previous article: https://www.jb51.net/article/160936.htm

Jsvc binds to the tomcat binary distribution, finds the source package, and prepares it for compilation into binaries.

Go to the bin directory under tomcat and find commons-daemon-native.tar.gz

Enter description here

Decompress the source code package

Tar-zxvf commons-daemon-native.tar.gz

Go to the extracted directory and compile

Cd commons-daemon-1.0.15-native-src/unix

. / configure-- with-java=$JAVA_HOME

Enter description here

The above error is that the gcc compilation environment is not installed.

Yum install gcc-c++-y

Run it again and the following will be fine.

Enter description here

Compile

Make

When the compilation is complete, a jsvc file is generated in the current folder

Enter description here

Copy it to the tomcat bin directory

Cp jsvc / usr/local/tomcat/bin/

Then we use daemon.sh to run our tomcat.

. / daemon.sh start

Other commands:

. / daemon.sh stop

Summary

The above is the editor to introduce to you the use of jsvc to start tomcat (use ordinary users to run, hope to help you, if you have any questions, please leave me a message, the editor will reply to you in time. Thank you very much for your support to the website!
