drwxr-xr-x 13 rolin staff 442 5 15 23:44 apache-tomcat-7.0.62-2

配置文件内容:

在conf/server.xml

localhost:tomcat rolin$ cat apache-tomcat-7.0.62-1/conf/server.xml

<?xml version=‘1.0‘ encoding=‘utf-8‘?>

<Resource name="UserDatabase" auth="Container"

</GlobalNamingResources>

<Connector port="8081" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8444" />

<Realm className="org.apache.catalina.realm.UserDatabaseRealm"

</Realm>

<Host name="localhost" appBase="webapps"

unpackWARs="true" autoDeploy="true">

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"

http://localhost:8081/

出现猫就是正确.

2.nginx安装:

Mac上是利用brew安装的

brew:安装,需要sudo权限

curl -LsSf http://github.com/mxcl/homebrew/tarball/master | sudo tar xvz -C/usr/local --strip 1

nginx安装命令:

brew install nginx

查看版本

nginx -V

nginx配置
