TOMCAT实验 - 技术栈

TOMCAT

一、TOMCAT功能介绍

1.1 安装TOMCAT

配置Java环境

[root@tomcat1 ~]#  yum install java-1.8.0-openjdk.x86_64 -y
[root@tomcat2 ~]#  dnf install java-1.8.0-openjdk.x86_64 -y

Java环境被存放在 /etc/alternatives/目录下

[root@tomcat1 ~]# ls /etc/alternatives/jre_openjdk

解压tomcat安装包到/usr/local/目录下，并制作软连接tomcat

[root@tomcat1 ~]# tar zxf apache-tomcat-9.0.93.tar.gz -C /usr/local/
[root@tomcat1 ~]# cd /usr/local/
[root@tomcat1 local]# ls
apache-tomcat-9.0.93  bin  etc  games  include  lib  lib64  libexec  sbin  share  src
[root@tomcat1 local]# ln -s apache-tomcat-9.0.93 tomcat
[root@tomcat1 local]# ls
apache-tomcat-9.0.93  bin  etc  games  include  lib  lib64  libexec  sbin  share  src  tomcat
[root@tomcat1 local]# cd tomcat/
[root@tomcat1 tomcat]# ls
bin  BUILDING.txt  conf  CONTRIBUTING.md  lib  LICENSE  logs  NOTICE  README.md  RELEASE-NOTES  RUNNING.txt  temp  webapps  work

[root@tomcat1 tomcat]# ls
bin  BUILDING.txt  conf  CONTRIBUTING.md  lib  LICENSE  logs  NOTICE  README.md  RELEASE-NOTES  RUNNING.txt  temp  webapps  work
bin->执行命令 conf->配置文件 lib->库 logs->日志 temps->临时文件 webapps->默认发布目录 work->工作目录

启动tomcat，查看端口

[root@tomcat1 bin]# ./startup.sh
[root@tomcat1 bin]# netstat -anltupe | grep java

浏览器访问

1.2 生成TOMCAT的启动文件

先进入conf文件中，看有没有相关编辑文件

没有，新建conf配置文件

[root@tomcat1 conf]# vim tomcat.conf
JAVA_HOME=/etc/alternatives/jre_openjdk

内容注释:JAVA配置环境

[root@tomcat1 conf]# vim /lib/systemd/system/tomcat.service
[Unit]
Description=Tomcat --- 服务名称
#After=syslog.target network.target remote-fs.target nss-lookup.target
After=syslog.target network.target --- 启动必须条件
[Service]
Type=forking --- 启动函数
EnvironmentFile=/usr/local/tomcat/conf/tomcat.conf ---配置文件
ExecStart=/usr/local/tomcat/bin/startup.sh --- 开启脚本
ExecStop=/usr/local/tomcat/bin/shutdown.sh --- 关闭脚本
PrivateTmp=true
User=tomcat
Group=tomcat
[Install]
WantedBy=multi-user.target

编写执行脚本

[root@tomcat1 conf]# vim/lib/systemd/system/tomcat.service
#!/bin/bash
case $1 in
  start)
  /usr/local/tomcat/bin/startup.sh
  ;;
  stop)
  /usr/local/tomcat/bin/shutdown.sh
  ;;
esac

添加可执行权限
[root@tomcat1 conf]# chmod +x /usr/bin/tomcat
