FastBull_IO Server/Front/Exchange ＯSCent

一、 同一服務器上安裝３個Tomcat

1.根目錄下創建dataExchange\dataFront\dataServer三個目錄，分別存放項目文件

2.在目錄/usr/local下創建三個Tomcat,分別命名：tomcatExchange\tomcatFront\tomcat\Server，

 cp /usr/local/tomcatExchange /usr/local/tomcatServer -r

單個項目下tomcatXXXX\conf\vhost\localhost.xml 分別配置好項目文件路徑。

<Host name="localhost" appBase="/dataExchange/wwwroot" unpackWARs="true" autoDeploy="true">
  <Context path="" docBase="/dataExchange/wwwroot" reloadable="false" crossContext="true"/>
  <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
    prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

3.設置各項目端口/usr/local/tomcatXXX/conf/server.xml
   ENTITY vhost-localhost SYSTEM "file:///usr/local/tomcatXXXXXx/conf/vhost/localhost.xml">
　tomcatExchange    Server port="8001"  Connector port="8081"
　tomcatFront           Server port="8002"  Connector port="8082"
　tomcatServer         Server port="8003"  Connector port="8083"

4.在路徑下/etc/init.d/,創建三個啓動文件 tomcatExchange/tomcatFront/tomcatServer

內容如下，注意修改每個文件的CATALINA_HOME=/usr/local/tomcatXXXXX

      echo -n -e "\n\e[00;31mkilling processes which didn't stop after $SHUTDOWN_WAIT seconds\e[00m"
      kill -9 $pid

  return 0

二、配置Ｍysql、Redis

三、安裝JAVA SDK 1.8
