第一步：
先是 安装apache系列
yum -y install httpd.x86_64 //++++++++++++++++++++++++++
yum -y install httpd-devel.x86_64 //+++++++++++++++++++++++++
运行# httpd -v 查看 版本，如：
第二步
安装jdk,设置JAVA-HOME、CLASS-PATH
第三步
根据httpd版本，下载mod_jk
http://archive.apache.org/dist/tomcat/tomcat-connectors/jk/
解压下载的
tomcat-connectors-1.2.46-src.tar.gz
# tar -xzvf
tomcat-connectors-1.2.46-src.tar.gz
查看是否有安装 gcc
#rpm -q gcc
[root@192 ~]# rpm -q gcc
gcc-4.8.5-44.el7.x86_64
如果没有则用yum安装
#yum -y install gcc
接着进入native文件夹
# cd /opt/tomcat-connectors-1.2.42-src/native
# ./configure –with-apxs=/usr/bin/apxs(此处apxs地址可能不一样，可用命令” whereis apxs “来查看)
# make
#make install
#cd apache-2.0
#cp mod_jk.so /etc/httpd/modules/mod_jk.so
第四步
下载tomcat:
https://archive.apache.org/dist/tomcat/tomcat-9/
根据自己的需求下载tomcat
第五步
(最重要)：整合Apache和Tomcat
进入apache安装路径下的conf文件夹，创建两个文件，mod_jk.conf以及workers.properties。
mod_jk.conf 内容如下：
#加载 mod_jk.so 文件，放置在最上
#加载 mod_jk.so 文件，放置在最上
LoadModule jk_module /etc/httpd/modules/mod_jk.so
#加载 tomcat 参数配置文件
JkWorkersFile /etc/httpd/conf/workers.properties
#日志保存文件
JkLogFile /var/log/httpd/mod_jk.log
#日志等级
JkLogLevel info
JkLogStampFormat “[%a %b %d %H:%M:%S %Y]”
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
#JkRequestLogFormat “%w %V %T”
#######请求拦截， controller负载均衡控制器名称
JkMount /servlet/* controller
JkMount /*.jsp controller
JkMount /*.do controller
JkMount /* controller
############## end #######################
接着：
其中，前两个参数（JkWorkerFile和JkLogFile(cd /var/log/httpd/ 之后 touch mod_jk.log)）具体的值会因为apache安装路径的不同而不同，此处需写入自己的apache服务器的路径。
文件末尾的几行JkMount意思是将符合条件的文件交给Tomcat处理。中间则是一些常规参数的设置。
workers.properties内容如下
#server
worker.list = controller
#========tomcat========
worker.tomcat.port=8009 #端口号与tomcat一致
worker.tomcat.host=localhost
worker.tomcat.type=ajp13
worker.tomcat.lbfactor = 1
#========tomcat2========
#worker.tomcat2.port=9009 #端口号与tomcat一致
#worker.tomcat2.host=localhost
#worker.tomcat2.type=ajp13
#worker.tomcat2.lbfactor = 1
#========controller=负载均衡控制器名称=======
worker.controller.type=lb
worker.controller.balanced_workers=tomcat #多个tomcat以”,”隔开
worker.controller.sticky_session=false
worker.controller.sticky_session_force=1
#worker.controller.sticky_session=1
第六步：
在/etc/httpd/conf/httpd.conf 最后边加上如下表示把这个文件载入
Include /etc/httpd/conf/mod_jk.conf
开启8080端口
firewall-cmd –permanent –add-port=8080/tcp
firewall-cmd –reload
第七步：
保存之后重启Apache和Tomcat。
service httpd restart
对于tomcat的启动要进入到tomcat文件夹下边
cd conf
vi server.xml
<Engine name=”Catalina” defaultHost=”localhost” jvmRoute=”controller”>
1
解开tomcat中对于8009端口的枷锁
<Connector port=”8009″ protocol=”AJP/1.3″redirectPort=”8443″ />
1
cd /opt/tomcat/bin
sh startup.sh
如果是重启｛sh startup.sh sh startdown.sh｝
如果出现Apache启动报错，那可能是mod_jk.so文件的版本跟Apache版本不符合，需要重新下载，编译。
访问页面的时候用http://192.168.200.2:8080
因为apache的是80 duankou
tomcat的是8080端口
打开默认网页之后是 /opt/tomcat/webapps/Root 下的index.jsp
可以在这个目录下创建对应的测试网页
# vi test.jsp
<html>
<body>
<center>Now time is: <%=new java.util.Date()%></center>
</body>
</html>
注意：
当启动httpd时，有以下报错时，可以按以下方法解决
#systemctl start httpd
报错：
Job for httpd.service failed because the control process exited with error code. See “systemctl status httpd.service” and “journalctl -xe” for details.
运行：
#journalctl -xe

6月 15 13:08:12 192.168.0.129 python[3792]: SELinux is preventing /usr/sbin/httpd from write access on the file /var/log/httpd/jk-runtime-status.3785.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that httpd should be allowed write access on the jk-runtime-status.3785 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c ‘httpd’ –raw | audit2allow -M my-httpd
# semodule -i my-httpd.pp
运行：
# ausearch -c ‘httpd’ –raw | audit2allow -M my-httpd
# semodule -i my-httpd.pp
然后再启动httpd，#systemctl start httpd 一切正常
