httpd 2.4 +Tomcat 7負載均衡

服務器：

http服務器：192.168.29.128

tomcat1：192.168.29.129

tomcat2：192.168.29.130

準備軟件：

jdk-7u79-linux-x64.gz
apache-tomcat-7.0.42.tar.gz
apr-1.5.2.tar.gz
apr-util-1.5.4.tar.bz2
httpd-2.4.20.tar.gz
pcre-8.37.tar.gz

1.安裝jdk，tomcat（此處教程繁多，再也不廢話）

2.編譯httpd（編譯環境：gcc，gcc-c++)

apr：

# tar xf apr-1.5.2.tar.bz2

# cd apr-1.5.2

#./configure --prefix=/usr/local/apr

# make && make install

 

apr-util：      

# tar xf apr-util-1.5.4.tar.bz2

# cd apr-util-1.5.4

#./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/

    --with-apr=/usr/local/apr/    ：指明apr安裝位置；

# make && make install

 

pcre：      

# tar xf pcre-8.37.tar.gz

# cd pcre

#./configure --prefix=/usr/local/ pcre-8.37

# make && make install

 

httpd：

# tar xf httpd-2.4.16.tar.bz2

# cd httpd-2.4.16

# ./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre

# make && make install

3.配置apache2.4

#cd /usr/local/apache2

①#vim conf/httpd.conf文件，

編輯：ServerName 192.168.28.128:80

加載如下模塊。

#---------------------start------------------------

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

LoadModule rewrite_module modules/mod_rewrite.so

LoadModule proxy_balancer_module modules/mod_proxy_balancer.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 slotmem_shm_module modules/mod_slotmem_shm.so

LoadModule speling_module modules/mod_speling.so

LoadModule lbmethod_byrequests_module modules/mod_lbmethod_byrequests.so

取消 Include conf/extra/httpd-vhosts.conf的註釋標記#。

文件末尾加上

<proxy balancer://cluster>

BalancerMember ajp://192.168.29.130:8009 loadfactor=1 route=jvm1

BalancerMember ajp://192.168.29.129:8009 loadfactor=1 route=jvm2

</proxy>

② #vim conf/extra/httpd-vhosts.conf

<VirtualHost *:80>
    ServerAdmin test@qq.com
    ServerName 192.168.29.130
    ServerAlias 192.168.29.130
    ProxyPass / balancer://cluster/ stickysession=jsessionid nofailover=On
    ProxyPassReverse / balancer://cluster/
    ErrorLog "logs/lbtest-error.log"
    CustomLog "logs/lbtest-access.log" common
</VirtualHost>

<VirtualHost *:80>
    ServerAdmin test@qq.com
    ServerName 192.168.29.129
    ServerAlias 192.168.29.129
    ProxyPass / balancer://cluster/ stickysession=jsessionid nofailover=On
    ProxyPassReverse / balancer://cluster/
    ErrorLog "logs/lbtest-error.log"
    CustomLog "logs/lbtest-access.log" common
</VirtualHost>

 

4.修改tomcat 配置文件

#cd apache-tomcat-7.0.42

#vim conf/server.xml

tomcat1:192.168.29.129

<Engine name="Catalina" defaultHost="localhost"  jvmRoute="jvm2" >

打開註釋：

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

一樣編輯另外一臺服務器配置

tomcat2:192.168.29.130

<Engine name="Catalina" defaultHost="localhost"  jvmRoute="jvm1" >

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>

 

5.啓動tomcat

啓動httpd

#cd /usr/local/apache2/bin

#./apachectl start

訪問http://192.168.29.128/項目路徑

大功告成。。。。
