CentOS离线安装Tomcat

一、获取安装文件

二、启动tomat

三、安装为系统服务

一、获取安装文件

本文安装的Tomcat为8.5.82版本，可以从官网很方便的获取，点击链接可以直达：Apache Tomcat® - Apache Tomcat 8 Software Downloads

直接下载tar.gz的压缩包即可，也可以点击链接直接下载：apache-tomcat-8.5.82.tar.gzhttps://dlcdn.apache.org/tomcat/tomcat-8/v8.5.82/bin/apache-tomcat-8.5.82.tar.gz

将下载的安装包上传到服务器上，例如上传到/mnt/software/tools文件夹下

使用tar命令解压：

[root@gts03 tools]# lltotal 815884-rw-r--r-- 1 root root  10610025 Aug 14 22:34 apache-tomcat-8.5.82.tar.gz-rw-r--r-- 1 root root 148162542 Aug 14 22:27 jdk-8u341-linux-x64.tar.gz-rw-r--r-- 1 root root 676676298 Aug 13 18:15 mysql-5.7.39-linux-glibc2.12-x86_64.tar.gz[root@gts03 tools]# tar -zxvf apache-tomcat-8.5.82.tar.gz

把解压后的文件夹移动到/mnt/software目录下，并重命名为tomcat-8.5.82-gtmall

[root@gts03 tools]# mv apache-tomcat-8.5.82 ../tomcat-8.5.82-gtmall[root@gts03 tools]# cd ..[root@gts03 software]# lltotal 32drwxr-xr-x 8 root  root   4096 Aug 14 22:36 jdk8drwx------ 2 root  root  16384 Aug 14 17:57 lost+founddrwxr-xr-x 9 mysql mysql  4096 Aug 14 18:05 mysqldrwxr-xr-x 9 root  root   4096 Aug 14 22:55 tomcat-8.5.82-gtmalldrwxr-xr-x 2 root  root   4096 Aug 14 22:56 tools

二、启动tomat

进入tomcat的bin目录，启动tomcat：

[root@gts03 bin]# cd /mnt/software/tomcat-8.5.82-gtmall/bin
[root@gts03 bin]# ./startup.sh Using CATALINA_BASE:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_HOME:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_TMPDIR: /mnt/software/tomcat-8.5.82-gtmall/tempUsing JRE_HOME:        /mnt/software/jdk8Using CLASSPATH:       /mnt/software/tomcat-8.5.82-gtmall/bin/bootstrap.jar:/mnt/software/tomcat-8.5.82-gtmall/bin/tomcat-juli.jarUsing CATALINA_OPTS:   Tomcat started.

浏览器中输入IP:8080，如果出现以下界面，说明安装成功：

三、安装为系统服务

CentOS系统中所有的服务在 /etc/init.d/ 目录下都对应一个脚本，新建一个服务也即新建一个脚本在该目录下。

这里新建 Tomcat的启动脚本。

vim /etc/init.d/tomcat-gtmall

#!/bin/sh -e
###必须添加，才能使用chkconfig命令设为自启动，2345参数表示,在哪些运行级别启动,启动序号61;关闭序号61；两位数字即可
#chkconfig:2345 61 61##JDK目录
export JAVA_HOME=/mnt/software/jdk8
export JRE_HOME=$JAVA_HOME/jre
export PATH=$PATH:$JAVA_HOME/bin
export CLASSPATH=.
export CATALINA_HOME=/mnt/software/tomcat-8.5.82-gtmallcase "$1" in
start)${CATALINA_HOME}/bin/startup.shexit 0;;
stop)${CATALINA_HOME}/bin/shutdown.shexit 0;;
debug)${CATALINA_HOME}/bin/shutdown.sh${CATALINA_HOME}/bin/catalina.sh runexit 0;;
force-reload|restart)${CATALINA_HOME}/bin/startup.sh${CATALINA_HOME}/bin/shutdown.shexit 0;;*)echo "Usage: /etc/init.d/tomcat-gtmall {start|stop|restart|force-reload|debug}"exit 1;;
esacexit 0

ESC:wq保存并退出。修改文件的权限：

chmod o+x /etc/init.d/tomcat-gtmall

添加为开机启动：

chkconfig --add tomcat-gtmall
chkconfig --list

先停止原来的服务，以服务形式启动：

[root@gts03 bin]# ./shutdown.sh Using CATALINA_BASE:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_HOME:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_TMPDIR: /mnt/software/tomcat-8.5.82-gtmall/tempUsing JRE_HOME:        /mnt/software/jdk8Using CLASSPATH:       /mnt/software/tomcat-8.5.82-gtmall/bin/bootstrap.jar:/mnt/software/tomcat-8rUsing CATALINA_OPTS:   [root@gts03 bin]# service tomcat-gtmall startUsing CATALINA_BASE:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_HOME:   /mnt/software/tomcat-8.5.82-gtmallUsing CATALINA_TMPDIR: /mnt/software/tomcat-8.5.82-gtmall/tempUsing JRE_HOME:        /mnt/software/jdk8/jreUsing CLASSPATH:       /mnt/software/tomcat-8.5.82-gtmall/bin/bootstrap.jar:/mnt/software/tomcat-8rUsing CATALINA_OPTS:   Tomcat started.

再次访问IP:8080,可以正常访问

执行./shutdown.sh时报错java.net.ConnectException: Connection refused

找到jdk安装目录下lib/security（/mnt/software/jdk8/jre/lib/security）文件夹下的java.security文件，将securerandom.source=file:/dev/random
修改为：securerandom.source=file:/dev/urandom

查看tomcat是否关闭ps -ef|grep java，如果有执行杀掉进程
