Mac下Tomcat安装&配置&80默认端口设置

序言: 在学习Tomcat时, 部署虚拟服务主机时,遇到了无响应的情况.原以为是应为Tomcat默认端口8080在调整至(进行端口转发设置)默认端口80会和Mac自带Apache起冲突.但是也有同学使用Mac却得到响应.这里笔者重新记录一下.

1 Tomcat的安装

进入阿帕奇官网http://tomcat.apache.org/ 如下图(最好点击Which version 判断你需要哪一个版本)

　　2. 笔者使用8.5.23版本兼容Java7以及之后的版本(由于先在大部分情况下公司使用Java6 or Java7)

　　点击 Core下的tar.gz 开始下载

　　3.将下载好的文件该名称为Tomcat方便后续使用

　　4.进入Mac下的资源库(/Library/) 将文件夹放到该处

　　5 进入终端(Terminal) 输入以下命令行

~$ cd /Library/Tomcat/bin
~$ ./startup.sh

　　./startup.sh表示开启Tomcat服务器

　　此时在页面地址栏输入localhost:8080(127.0.0.1 Tomcat默认端口是8080)会出现可爱的小猫即Tomcat页面

　　./shutdown.sh表示关闭服务器

　　注意:由于Mac是Unix,同Linux一样1024以下端口是没有监听权限的,当将Tomcat设置为默认80端口是无法响应的

2 设置默认80端口

mac下8080端口到80端口的转发
MAC OS 本质上还是 Unix 系统, Unix 系统大多默认情况下非root用户是无法使用小于1024的常用端口的.这时候如果你开发中需要在普通用户下用到80端口, 比如 tomcat, 比如 vitualbox 下构建了一个 http 服务, 若你想直接通过浏览器的 localhost 访问的话(不用加上莫名其妙的”:端口”的话)你就需要做一些系统端口转发的工作.

MAC OS 10.10 上 pfctl 就可以做这一件事情, 详情请参见

1、创建文件 :

sudo vim /etc/pf.anchors/eclipse.tomcat.forwarding

文件内容：

rdr pass on lo0 inet proto tcp from any to 127.0.0.1 port 80 -> 127.0.0.1 port 8080
rdr pass on lo0 inet proto tcp from any to 127.0.0.1 port 443 -> 127.0.0.1 port 8443
2、创建文件 :

sudo vim /etc/pf-tomcat.conf
文件内容：

rdr-anchor "forwarding"
load anchor "forwarding"from "/etc/pf.anchors/eclipse.tomcat.forwarding"
3、启动
sudo pfctl -ef /etc/pf-tomcat.conf
执行结果
复制代码
root@ymdeMacBook-Air etc# sudo pfctl -ef /etc/pf-tomcat.conf
pfctl: Use of -f option, could result in flushing of rules
present in the main ruleset added by the system at startup.
See /etc/pf.conf for further details.

No ALTQ support in kernel
ALTQ related functions disabled
pf enabled　
复制代码
假设你的工程 http://localhost/myDemo.html 这时访问你的web工程, 你会发现 http://localhost/myDemo.html 这个不需要8080端口即可访问，加上 http://localhost:8080/myDemo.html 访问不了。

4、关闭
sudo pfctl -d
执行结果
root@ymdeMacBook-Air etc# sudo pfctl -d
No ALTQ support in kernel
ALTQ related functions disabled
pf disabled
这时你访问你的web工程, 你会发现 http://localhost/myDemo.html 这个访问不了，加上 http://localhost:8080/myDemo.html 即可访问。

或者全部关闭
pfctl -F all -f /etc/pf.conf

然并卵 本人依然无法使用80端口 localhost显示 it works 是Apache服务器使用着

输入以下代码查看80端口的占用情况

~$ lsof -i:80

笔者关闭了lantern 并关闭了Apache服务器

关闭Apache

~$ sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

启动Apache

~$ sudo launchctl load -w /System/Library/LaunchDaemons/org.apache.httpd.plist

关闭Apache之后,查看80端口现在已经没有占用情况了

重新设置80端口转发

~$ sudo pfctl -ef /etc/pf-tomcat.conf

再去浏览器输入localhost看看

成功了!!!
