2. To set up the JBoss Web Server for systemd, run the .postinstall.systemd script as the root user:

   # cd JWS_HOME/tomcat
   # sh .postinstall.systemd

3. To control the JBoss Web Server with systemd, you can perform any of the following steps as the root user:

   • To enable the JBoss Web Server services to start at system startup by using systemd:

     # systemctl enable jws5-tomcat.service

     Copy to Clipboard Toggle word wrap

   • To start the JBoss Web Server by using systemd:

     # systemctl start jws5-tomcat.service

     Copy to Clipboard Toggle word wrap
     Note

     The SECURITY_MANAGER variable is now deprecated for JBoss Web Server configurations that are based on archive file installations. Consider the following deprecation comment:

     # SECURITY_MANAGER has been deprecated. To run tomcat under the Java Security Manager use:
       JAVA_OPTS="-Djava.security.manager -Djava.security.policy==\"$CATALINA_BASE/conf/"catalina.policy\"""

   • To stop the JBoss Web Server by using systemd:

     # systemctl stop jws5-tomcat.service

     Copy to Clipboard Toggle word wrap

   • To verify the status of the JBoss Web Server by using systemd:

     # systemctl status jws5-tomcat.service

     Note

     Any user can run the status operation.

Procedure

1. If JBoss Web Server is already running, stop JBoss Web Server as the tomcat user. For more information, see Stopping JBoss Web Server from the command line when installed from an archive file.

2. To view the current UID and GID for the tomcat user and group, enter the following command as the root user:

   id tomcat

   The preceding command displays the user account and group details. For example:

   uid=53(tomcat) gid=53(tomcat) groups=53(tomcat)

3. To assign a new GID to the tomcat group, enter the following command as the root user:

   groupmod -g <new_gid> tomcat

   Copy to Clipboard Toggle word wrap

   For example:

   groupmod -g 410 tomcat

4. To assign a new UID to the tomcat user, enter the following command as the root user:

   usermod -u <new_uid> -g <new_gid> tomcat

   Copy to Clipboard Toggle word wrap

   For example:

   usermod -u 401 -g 410 tomcat

5. To reassign file and directory permissions to the new UID, enter the following command as the root user:

   # find / -not -path '/proc*' -uid <original_uid> | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown($ug,-1,$fn);chmod($m,$fn)}' <new_uid>

   Copy to Clipboard Toggle word wrap

   In the preceding command, replace <original_uid> with the old UID and replace <new_uid> with the new UID. For example, to reassign file and directory permissions from UID 53 to UID 401, enter the following command:

   # find / -not -path '/proc*' -uid 53 | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown($ug,-1,$fn);chmod($m,$fn)}' 401

6. To reassign file and directory permissions to the new GID, enter the following command as the root user:

   # find / -not -path '/proc*' -gid <original_gid> | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown(-1,$ug,$fn);chmod($m,$fn)}' <new_gid>

   Copy to Clipboard Toggle word wrap

   In the preceding command, replace <original_gid> with the old GID and replace <new_gid> with the new GID. For example, to reassign file and directory permissions from GID 53 to GID 410, enter the following command:

   # find / -not -path '/proc*' -gid 53 | perl -e '$ug = @ARGV[0]; foreach $fn (<STDIN>) { chomp($fn);$m = (stat($fn))[2];chown(-1,$ug,$fn);chmod($m,$fn)}' 410
