tomcat8 开机自启动

参考：https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/System_Administrators_Guide/sect-Managing_Services_with_systemd-Services.html#sect-Managing_Services_with_systemd-Services-List

在tomcat的bin目录下创建setenv.sh,catalina.sh 启动时候会自动调用

[root@klmy-460-res01 ~]# vi /usr/local/apache-tomcat-8.5.6/bin/setenv.sh

 编辑setenv.sh

#add tomcat pid
CATALINA_PID="$CATALINA_BASE/tomcat.pid"
#add java opts
JAVA_OPTS="-server -XX:PermSize=256M -XX:MaxPermSize=1024m -Xms512M -Xmx1024M -XX:MaxNewSize=256m"

 

添加tomcat.service

[root@klmy-460-res01 ~]# vi /usr/lib/systemd/system/tomcat.service
添加内容：
[Unit]
Description=Tomcat
After=syslog.target network.target remote-fs.target nss-lookup.target
   
[Service]
Type=forking
PIDFile=/usr/local/apache-tomcat-8.5.6/tomcat.pid    
ExecStart=/usr/local/apache-tomcat-8.5.6/bin/startup.sh    
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target  

 

 

配置开机启动tomcat.service

[root@klmy-460-res01 ~]# systemctl enable tomcat
Created symlink from /etc/systemd/system/multi-user.target.wants/tomcat.service to /usr/lib/systemd/system/tomcat.service.

 

启动tomcat服务

[root@klmy-460-res01 ~]# systemctl start tomcat  
Job for tomcat.service failed because the control process exited with error code. See "systemctl status tomcat.service" and "journalctl -xe" for details.

 启动失败，有错误查看错误信息：

[root@klmy-460-res01 ~]# systemctl status tomcat

经过检查$JAVA_HOME 和$JRE_HOME都是正常的。

解决办法在catlina.sh 最上面导入home:

export JAVA_HOME=/usr/local/jdk1.8.0_111
export JRE_HOME=/usr/local/jdk1.8.0_111/jre

 

重新启动服务并查看状态：

[root@klmy-460-res01 ~]# systemctl start tomcat  
[root@klmy-460-res01 ~]# systemctl status tomcat

重启服务器：

[root@klmy-460-res01 ~]# firewall-cmd --zone=public --list-ports 
443/tcp 80/tcp 8080/tcp
[root@klmy-460-res01 ~]# reboot

 

客户端windows 命令行测试一下：

telnet 服务器ip 端口
