Apache Http Server采用ajp协议配置tomcat负载均衡

192.168.1.177--->apache http server
192.168.1.178--->apache-tomcat-8.0.32
192.168.1.179--->apache-tomcat-8.0.32

ssh登录192.168.1.177
[root@apachehs opt]# vi /etc/hosts
192.168.1.177   apachehs
[root@apachehs opt]# yum install gcc
[root@apachehs opt]# yum install -y gcc gcc-c++

下面安装apr、apr-util、pcre
[root@apachehs opt]# tar -xvf apr-1.5.2.tar.gz
[root@apachehs opt]# cd apr-1.5.2
[root@apachehs apr-1.5.2]# vi configure
? $RM "$cfgfile"
添加#注释掉这一行

[root@apachehs apr-1.5.2]# ./configure --prefix=/usr/local/apr
[root@apachehs apr-1.5.2]# make && make install

[root@apachehs apr-1.5.2]# cd ..
[root@apachehs opt]# tar xvf apr-util-1.5.4.tar.gz
[root@apachehs opt]# cd apr-util-1.5.4
[root@apachehs apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-

apr=/usr/local/apr/bin/apr-1-config
[root@apachehs apr-util-1.5.4]# make && make install
[root@apachehs apr-util-1.5.4]# cd ..
[root@apachehs opt]# unzip pcre-8.38.zip -d /opt/
[root@apachehs opt]# cd pcre-8.38
[root@apachehs pcre-8.38]# vi configure
? $RM "$cfgfile"
添加#注释掉这一行

[root@apachehs pcre-8.38]# ./configure --prefix=/usr/local/pcre
[root@apachehs pcre-8.38]# make && make install

下面安装Apache Http Server
[root@apachehs httpd-2.4.18]# tar xvf httpd-2.4.18.tar.gz
[root@apachehs home]# cd httpd-2.4.18
[root@apachehs httpd-2.4.18]# ./configure --prefix=/home/webserver/apache --with-
apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre
[root@apachehs httpd-2.4.18]# make
[root@apachehs httpd-2.4.18]# make install
[root@apachehs httpd-2.4.18]# cd /home/webserver/apache/conf
[root@apachehs conf]# ls
extra  httpd.conf  magic  mime.types  original

下面开始配置Apache Http Server
http://httpd.apache.org/docs/2.4/en/mod/mod_proxy_ajp.html
http://httpd.apache.org/docs/2.4/en/mod/
[root@apachehs home]# vi httpd.conf
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so

LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule slotmem_shm_module modules/mod_slotmem_shm.so
LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so

# Virtual hosts
Include conf/extra/httpd-vhosts.conf

找到#Listen 80...一行，在下面添加
Listen 192.168.1.177:10080
找到#ServerName ...一行，在下面添加
ServerName 192.168.1.177:10080

在文件的最后加上如下几行:
ProxyRequests Off
<Proxy balancer://clu>
BalancerMember ajp://192.168.1.178:8009 loadfactor=1
BalancerMember ajp://192.168.1.179:8009 loadfactor=1
</Proxy>

[root@apachehs conf]# vi extra/httpd-vhosts.conf
<VirtualHost *:10080>
    # ServerAdmin [email protected]
    # DocumentRoot "/home/webserver/apache/docs/dummy-host.example.com"
    ServerName 192.168.1.177:10080
    # ServerAlias www.shihuan.example.com
    ProxyPass / balancer://clu/ stickysession=JSESSIONID nofailover=On
    ProxyPassReverse / balancer://clu/
    ErrorLog "logs/cluster-error.log"
    CustomLog "logs/custer-access.log" common
</VirtualHost>

[root@apachehs conf]# vi /etc/httpd/conf/httpd.conf
添加
ServerName 192.168.1.177:10080

[root@apachehs home]# /home/webserver/apache/bin/apachectl -k start
[root@apachehs home]# /home/webserver/apache/bin/apachectl -k stop

export PATH=$JAVA_HOME/bin:$PATH

[root@tomcat1 conf]# cd ../bin
[root@tomcat1 bin]# ./startup.sh
[root@tomcat1 bin]# ./shutdown.sh


----------------------------------------------------------------------------------
ssh登录192.168.1.179
[root@tomcat2 home]# vi /etc/hosts
192.168.1.179   tomcat2


[root@tomcat2 home]# rpm -ivh jdk-7u80-linux-x64.rpm
[root@tomcat2 home]# vi /etc/profile

[root@tomcat2 conf]# cd ../bin
[root@tomcat2 bin]# ./startup.sh
[root@tomcat2 bin]# ./shutdown.sh


----------------------------------------------------------------------------------


最后启动测试两个tomcat和apacheserver，启动顺序不能错

[root@ tomcat1 bin]# ./startup.sh
[root@ tomcat2 bin]# ./startup.sh
[root@ apachehs home]# /home/webserver/apache/bin/apachectl -k start

在浏览器的地址栏里输入 http://192.168.1.177:10080/

【注】如果在Windows Server上安装Apche Http Server需要先用管理员身份运行vcredist x64.exe这个文件。
