tomcat安装

第一步：官网下载安装包
https://tomcat.apache.org/

第二步：上传安装包
[root@ken ~]# rz 没有 lrzsz 需要下载 yum install lrzsz -y
[root@ken ~]# ls
apache-tomcat-9.0.17.zip fuhai-jpress-alpha.zip 没有 unzip 需要下载 yum install unzip -y
[root@ken ~]#

第三步：解压安装包
[root@ken ~]# unzip apache-tomcat-9.0.17.z
第四步：移动文件到/usr/local
[root@ken ~]# mv apache-tomcat-9.0.17 /usr/local/tomcat 移动并且改名

第五步：加执行权限 查看有没有权限 cd / usr/local/tomcat/bin/ 查看权限 ls -l
都是没有执行权限
[root@ken local]# chmod -R +x tomcat/ Tomcat 后面加 / 表示tomcat下面所有文件增加权限

第六步：下载java环境（jdk）
[root@ken bin]# yum install java -y #java-1.8.0-openjdk

第七步：启动tomcatcd cd /usr/local/tomcat/bin 然后开启tomcat的开启文件
[root@ken bin]# ./startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.

第八步：检测端口
[root@ken bin]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 1 ::ffff:127.0.0.1:8005 :::*
LISTEN 0 100 :::8009 :::*
LISTEN 0 100 :::8080 :::*
LISTEN 0 128 :::80 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*

第九步：浏览器访问
ip:8080
略

第十步：关闭tomcat
[root@ken bin]# ./shutdown.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar


tomcat网站根目录

webapps

tomcat日志

logs/catalina.out
tomcat主配置文件

[root@ken tomcat]# vim conf/server.xml /usr/local/tomcat/conf/server.xml

<Server port=”8005″ shutdown=”SHUTDOWN”>
<Connector port=”8080″ protocol=”HTTP/1.1″
<Connector port=”8009″ protocol=”AJP/1.3″ redirectPort=”8443″ />
<Host name=”localhost” appBase=”webapps”

8005端口接收shutdown指令 cd
[root@ken tomcat]# telnet 127.0.0.1 8005
Trying 127.0.0.1…
Connected to 127.0.0.1.
Escape character is ‘^]’.
SHUTDOWN
Connection closed by foreign host.
[root@ken tomcat]#
[root@ken tomcat]#
[root@ken tomcat]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 128 :::80 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*

vim /etc/profile.d/tomcat.sh 通用于apache
编写脚本
#!/bin/bash
export PATH=/usr/local/tomcat/bin/:$PATH
开启端口 startup.sh 关闭端口 shutdown.sh


tomcat多实例部署-三台

第一步：复制两份tomcat文件
[root@ken local]# ls
bin etc games include lib lib64 libexec sbin share src tomcat
[root@ken local]# cp tomcat tomcat1 -a
[root@ken local]# cp tomcat tomcat2 -a
[root@ken local]# ls
bin etc games include lib lib64 libexec sbin share src tomcat tomcat1 tomcat2

第二步：修改tomcat1端口cp cd /usr/local/tomcat1/conf/server.xml
只需要修改两处：
8005–》8006c:
8080–》8081
ml
第三步：修改tomcat2端口
只需要修改两处：
8005–》8007
8080–》8082

第四步：启动各个tomcat实例
[root@ken local]# tomcat/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat
Using CATALINA_HOME: /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
[root@ken local]# tomcat1/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat1
Using CATALINA_HOME: /usr/local/tomcat1
Using CATALINA_TMPDIR: /usr/local/tomcat1/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat1/bin/bootstrap.jar:/usr/local/tomcat1/bin/tomcat-juli.jar
Tomcat started.
[root@ken local]# tomcat2/bin/startup.sh
Using CATALINA_BASE: /usr/local/tomcat2
Using CATALINA_HOME: /usr/local/tomcat2
Using CATALINA_TMPDIR: /usr/local/tomcat2/temp
Using JRE_HOME: /usr
Using CLASSPATH: /usr/local/tomcat2/bin/bootstrap.jar:/usr/local/tomcat2/bin/tomcat-juli.jar
Tomcat started.

第五步：查看端口
[root@ken local]# ss -tnl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 100 127.0.0.1:25 *:*
LISTEN 0 1 ::ffff:127.0.0.1:8005 :::*
LISTEN 0 100 :::8009 :::*
LISTEN 0 100 :::8080 :::*
LISTEN 0 128 :::80 :::*
LISTEN 0 100 :::8081 :::*
LISTEN 0 100 :::8082 :::*
LISTEN 0 128 :::22 :::*
LISTEN 0 100 ::1:25 :::*

第六步：访问网站
略
