Tomcat 8 daemon settings in CentOS 7

Tomcat 8 is set in the Chszs of the CentOS 7 daemon and must be reproduced. Blog home: http://blog.csdn.net/chszs1, build Jsvc

JSVC is a toolkit developed specifically for Java applications, and the goal is to convert the normal run of Java applications to run as a UNIX daemon. This makes it easy to start/stop the application. The bin subdirectory of the Tomcat installation package contains the source code for the JSVC Toolkit, which is easy to build, as follows.

The script in this article takes Tomcat 8.0.27,centos 7 as an example. Suppose my Java 8 is installed at/OPT/JDK8.

$ cd /opt/tomcat8/bin$ sudo tar zvxf commons-daemon-native.tar.gz$ cd commons-daemon-1.0.15-native-src/unix$ sudo ./configure --with-java=/opt/jdk8$ sudo make$ sudo cp jsvc ../..

2. Create a Tomcat user

The following command creates a dedicated user to run the Tomcat instance and assigns ownership of the/opt/tomcat directory and its files to the newly created Tomcat user.

$ sudo useradd -r -s /sbin/nologin tomcat$ sudo chown -R tomcat: /opt/tomcat8

3. Create a system service

In the case of a centos system (e.g. CentOS 7), follow the steps below.

1) Create a system service script named Tomcat.service.

# vim /usr/lib/systemd/system/tomcat.service

2) Add the following:

  [Unit]description=apache Tomcat 8 WEB Application containerafter=network.target[service]type= forkingpidfile=/var/run/tomcat.pidenvironment=catalina_pid=/var/run/tomcat.pidenvironment=java_home=/opt/ jdk8environment=catalina_home=/opt/tomcat8environment=catalina_base=/opt/tomcat8environment=catalina_opts=             Execstart=/opt/tomcat/bin/jsvc-dcatalina.home=${catalina_home}-dcatalina.base=${catalina_base} -CP ${catalina_home}/bin/commons-daemon.jar:${catalina_home}/bin/bootstrap.jar:${catalina_home}/bin/tomcat-juli . Jar-user Tomcat-java-home ${java_home}-pidfile/var/run/tomcat.pid-er Rfile syslog-outfile SYSLOG $CATALINA _opts Org.apache.catalina.startup.BootstrapExecS Top=/opt/tomcat8/bin/jsvc-pidfile/var/run/tomcat.pid-stop Org.apache.catalina.start Up. Bootstrap[install]wantedby=multi-user.target  

Developers can modify the catalina_opts option to suit their needs.

3) Let the Tomcat service run automatically after it starts:

$ sudo systemctl enable /usr/lib/systemd/tomcat.serviceln -s ‘/usr/lib/systemd/tomcat.service‘ ‘/etc/systemd/system/multi-user.target.wants/tomcat.service‘ln -s ‘/usr/lib/systemd/tomcat.service‘ ‘/etc/systemd/system/tomcat.service‘

4) Use the following command to start, restart, and stop the Tomcat service

$ systemctl start tomcat$ systemctl stop tomcat$ systemctl restart tomcat$ systemctl status tomcat

4. Firewall settings

Firewall Open port 8080

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