apache反向代理後端tomcat
阿新 • • 發佈：2020-10-09
在各種企業級網站應用系統中，JSP也是使用較多的一種網站開發語言，對於這樣的網站伺服器，必須能夠支援Java環境、JSP解析，比如安裝Tomcat、Jboss等JSP容器。另外一方面，Apache HTTP Server對靜態HTML頁面的處理能力要更加優秀一些，因此若能將Apache與Tomcat等JSP容器整合在一起使用，將可以獲得更好的網站服務體驗。
這種情況下，Apache仍然作為瀏覽器訪問的前端服務，當客戶機請求訪問*.jsp網頁時，再自動呼叫後端的tomcat服務進行解析，並將結果頁面返回給客戶機。其間的溝通過程需要安裝聯結器mod_jk來完成。
後端安裝Tomcat：

在前端伺服器安裝apache
[[email protected]http]#tarxfapr-1.5.1.tar.gz [[email protected]http]#cdapr-1.5.1 [[email protected]apr-1.5.1]#./configure--prefix=/usr/local/apr [[email protected]apr-1.5.1]#make&&makeinstall [[email protected]http]#tarxfapr-util-1.5.4.tar.gz [[email protected]http]#cdapr-util-1.5.4 [[email protected]apr-util-1.5.4]#./configure--prefix=/usr/local/apr-util--with-apr=/usr/local/apr [[email protected]apr-util-1.5.4]#make&&makeinstall with-apr=/usr/local/apr [[email protected]setup]#tarjxfpcre-8.35.tar.bz2 [[email protected]setup]#cdpcre-8.35 [roo[email protected]pcre-8.35]#./configure [[email protected]pcre-8.35]#make&&makeinstall [[email protected]httpd-2.4.10]#./configure--prefix=/usr/local/apache--enable-so--enable-ssl\ --enable-cgi--enable-rewrite--with-zlib--with-pcre--with-apr=/usr/local/apr\ --with-apr-util=/usr/local/apr-util/--enable-mpms-shared=all--with-mpm=event\ --enable-proxy--enable-proxy-http--enable-proxy-ajp--enable-proxy-balancer\ --enable-lbmethod-heartbeat--enable-hearbeat--enable-slotmem-shm--enable-slotmem-plain--enable-watchdog [[email protected]httpd-2.4.10]#make&&makeinstall [[email protected]conf]#vim/usr/local/apache/conf/httpd.conf LoadModuleslotmem_shm_modulemodules/mod_slotmem_shm.so//開啟這個模組
第一種方法apache直接代理tomcat：
[[email protected]conf]#vim/usr/local/apache/conf/httpd.conf //引入配置檔案 include/usr/local/apache/conf/http-proxy.conf [[email protected]conf]#vimhttp-proxy.conf //在配置檔案新增以下內容 <VirtualHost*:80> ProxyViaOn ProxyRequestsOff ProxyPreserveHostOn ProxyPass/http://192.168.1.115:8080 ProxyPa***everse/http://192.168.1.115:8080 <Proxy*> Requireallgranted </Proxy> <Location/> Requireallgranted </Location> </VirtualHost>
第二種方法使用mod_jk代理：
[[email protected]setup]#wegethttp://mirrors.cnnic.cn/apache/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.40-src.tar.gz [[email protected]setup]#tarxftomcat-connectors-1.2.40-src.tar.gz [[email protected]setup]#cdtomcat-connectors-1.2.40-src/native/ [[email protected]native]#./configure--with-apxs=/usr/local/apache/bin/apxs [[email protected]native]#make&&makeinstall [[email protected]modules]#ls/usr/local/apache/modules/|grep"mod_jk.so" mod_jk.so [[email protected]conf]#vim/usr/local/apache/conf/httpd.conf //新增以下內容： LoadModulejk_modulemodules/mod_jk.so JkWorkersFile/usr/local/apache/conf/workers.properties JkLogFilelogs/mod_jk.log JkLogLeveldebug JkShmFilelogs/jk.shm JkMount/*Tomcat JkMount/status/stat [[email protected]conf]#vimworkers.properties //容器配置檔案 worker.list=Tomcat,stat1 worker.Tomcat.port=8009 worker.Tomcat.host=192.168.1.116 worker.Tomcat.type=ajp13 worker.Tomcat.lbfactor=1 worker.stat.type=status 重啟apache
