第一季：Tomcat 8迷情】 第7集 apache http server+tomcat+mod_jk在linux上的负载均衡配置
1.安装mod_jk# wget http://mirrors.hust.edu.cn/apache/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.40-src.tar.gz
# tar xzvf tomcat-connectors-1.2.40-src.tar.gz
# cd tomcat-connectors-1.2.40-src
# cd native/
#./configure --with-apxs=/usr/local/apache2/bin/apxs
# make
# cd apache-2.0/
# ls
bldjk54.qclsrcconfig.m4Makefile.apxs Makefile.inmod_jk.amod_jk.dspmod_jk.lomod_jk.so
bldjk.qclsrc Makefile Makefile.apxs.inMakefile.vcmod_jk.cmod_jk.la mod_jk.o NWGNUmakefile
# cp mod_jk.so /usr/local/apache2/modules/
2.创建httpd-jk.conf
# vi httpd-jk.conf
# Load the mod_jk
LoadModulejk_modulemodules/mod_jk.so
JkWorkersFileconf/workers.properties
JkLogFilelogs/mod_jk.log
JkLogLeveldebug
JkMount/*myCluster 3.创建workers.properties
# vi workers.properties
worker.list=myCluster
worker.TomcatA.port=8009
worker.TomcatA.host=192.168.146.128
worker.TomcatA.type=ajp13
worker.TomcatA.lbfactor=1
worker.TomcatB.port=8009
worker.TomcatB.host=192.168.146.130
worker.TomcatB.type=ajp13
worker.TomcatB.lbfactor=1
worker.myCluster.type=lb
worker.myCluster.balance_workers=TomcatA,TomcatB
worker.myCluster.sticky_session = 0 4.配置httpd.conf
# vi httpd.conf
将以下module注释去掉：
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule proxy_ftp_module modules/mod_proxy_ftp.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
LoadModule proxy_scgi_module modules/mod_proxy_scgi.so
LoadModule proxy_wstunnel_module modules/mod_proxy_wstunnel.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
LoadModule proxy_express_module modules/mod_proxy_express.so
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so
LoadModule lbmethod_bytraffic_module modules/mod_lbmethod_bytraffic.so
LoadModule lbmethod_bybusyness_module modules/mod_lbmethod_bybusyness.so
LoadModule lbmethod_heartbeat_module modules/mod_lbmethod_heartbeat.so 将mod_jk.conf配置加载到系统中：
Include conf/httpd-jk.conf
5.启动apache
# ./apachectl start
6.测试

页面显示正常表示配置成功了！
