整合Apache2.4 Resin3.1

Resin是一个常用的java中间件，对servlet和JSP提供了良好的支持，同时也支持HTTP。所以Resin可以独立部署成web服务器，处理所有的http静态与JSP动态请求。更多时候会通过将Apache/IIS与Resin整合的方式，将动态请求与静态请求分开，让Apache/IIS处理静态请求，Resin专注处理JSP的动态请求，这样能够最大的发挥Apache与Resin的优势，有效调高服务器的处理效率。本文作者: cubix 博客地址: http://cubix.blog.51cto.com/文章参考： href="http://coolerfeng.blog.51cto.com/133059/54422/" target=_blank>http://coolerfeng.blog.51cto.com/133059/54422/
一、基础环境说明与配置 本次使用Centos6.7，编译安装Apache2.4.20、Resin-3.1.14。1.关闭SELINUX，配置yum源。

##关闭SeLinux
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=permissive/g' /etc/selinux/config
##下载CentOS6源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo yum makecache

2.源码包下载。

##下载Apache2.4编译所需的apr、apr-util、pcre
wget http://apache.fayea.com//apr/apr-1.5.2.tar.gz -O /usr/local/src/apr-1.5.2.tar.gz
wget http://apache.fayea.com//apr/apr-util-1.5.4.tar.gz -O /usr/local/src/apr-util-1.5.4.tar.gz
wget --no-check-certificate https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gz -O /usr/local/src/pcre-8.40.tar.gz
##下载Apache-2.4.20
wget http://archive.apache.org/dist/httpd/httpd-2.4.20.tar.gz -O /usr/local/src/httpd-2.4.20.tar.gz
##下载Resin-3.1.14
wget http://www.caucho.com/download/resin-3.1.14.tar.gz  -O /usr/local/src/resin-3.1.14.tar.gz
##jdk下载地址 http://www.oracle.com/technetwork/java/javase/archive-139210.html ##jdk下载需要先登录oracle账户，先下载好jdk，再放到服务器的/usr/local/src目录。
##本文使用jdk-6u29-linux-x64.bin

二、编译安装Apache、Resin1.安装依赖包

yum install -y gcc gcc-c++  openssl openssl-devel perl

2.编译安装Apache2.4所依赖的apr、apr-util、pcre

cd /usr/local/src/
##解压所有压缩包
tar xf apr-1.5.2.tar.gz
tar xf apr-util-1.5.4.tar.gz
tar xf pcre-8.40.tar.gz
tar xf httpd-2.4.20.tar.gz
tar xf resin-3.1.14.tar.gz

##编译apr
cd /usr/local/src/apr-1.5.2
./configure --prefix=/usr/local/apr
make && make install
##编译apr-util
cd /usr/local/src/apr-util-1.5.4
./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
make && make install
##编译pcre
cd /usr/local/src/pcre-8.40
./configure --prefix=/usr/local/pcre
make && make install

3.编译安装Apache-2.4.20

cd /usr/local/src/httpd-2.4.20
./configure \
--prefix=/usr/local/apache-2.4.20 \
--with-apr-util=/usr/local/apr-util/ \
--with-apr=/usr/local/apr/ \
--with-pcre=/usr/local/pcre/ \
--enable-mods-shared=most \
--enable-mpms-shared=all \
--enable-modules=most \
--enable-rewrite \
--enable-ssl  \
--enable-so

make && make install

##为apache添加软连接，方便版本切换
ln -s /usr/local/apache-2.4.20 /usr/local/apache

##配置apache开机自动启动
echo '/usr/local/apache/bin/apachectl start ' >> /etc/rc.local

4.配置JAVA环境

##安装JDK1.6
cd /usr/local/src/
./jdk-6u29-linux-x64.bin
mv /usr/local/src/jdk1.6.0_29 /usr/local/jdk1.6.0_29

##为jdk添加软连接，方便版本切换
ln -s /usr/local/jdk1.6.0_29 /usr/local/jdk

##配置jdk到环境变量中
cat >> /etc/profile  <<EOF
############ Set JAVA Environment ############
export JAVA_HOME=/usr/local/jdk
export PATH=\$JAVA_HOME/bin:$PATH
EOF

##重新加载环境变量
source  /etc/profile

##验证JAVA环境
[root@web ~]# echo $JAVA_HOME
/usr/local/jdk
[root@web ~]# java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
Java HotSpot(TM) 64-Bit Server VM (build 20.4-b02, mixed mode)

5.编译安装Resin-3.1.14

##将apr、apr-util、pcre的C语言头文件添加到apache中（作用请见下文）
ln -s /usr/local/pcre/include/* /usr/local/apache/include/
ln -s /usr/local/apr/include/apr-1/* /usr/local/apache/include/
ln -s /usr/local/apr-util/include/apr-1/* /usr/local/apache/include/

##修改mod_caucho.c中的api变量名（作用请见下文）
sed -i 's/remote_ip/client_ip/g' /usr/local/src/resin-3.1.14/modules/c/src/apache2/mod_caucho.c
sed -i 's/remote_addr/client_addr/g' /usr/local/src/resin-3.1.14/modules/c/src/apache2/mod_caucho.c

##编译Resin
cd /usr/local/src/resin-3.1.14
./configure \
--prefix=/usr/local/resin-3.1.14 \
--with-apxs=/usr/local/apache/bin/apxs
make && make install

##为Resin添加软连接，方便版本切换
ln -s /usr/local/resin-3.1.14 /usr/local/resin

##配置apache开机自动启动
echo '/usr/local/resin/bin/httpd.sh  start' >> /etc/rc.local

##检验Resin与Apache联配的模块是否成功编译
#1.检查模块是否生成
ls /usr/local/apache/modules/ |grep caucho
mod_caucho.so  ##modules目录中存在模块

#2.检查Apache主配置文件中是否已加载模块
tail /usr/local/apache/conf/httpd.conf
#
# mod_caucho Resin Configuration
#
LoadModule caucho_module /usr/local/apache-2.4.20/modules/mod_caucho.so
ResinConfigServer localhost 6800
CauchoConfigCacheDirectory /tmp
CauchoStatus yes

#ResinConfigServer localhost 6800 #此配置作用是将JSP的请求转发到本地的6800端口，6800为Reisn默认的监控端口。如果在resin中修改了此端口，则该配置的端口也应该一起修改。

三、配置Apache与Resin1.配置Apache

##备份配置文件。
cp /usr/local/apache/conf/httpd.conf /usr/local/apache/conf/httpd.conf.back
##创建一个conf.d目录。将apache的虚拟主机配置统一存放在此目录中，方便维护管理
mkdir -p /usr/local/apache/conf/conf.d/
## 预配置Apache，关闭Apache的版本信息
cat >>/usr/local/apache/conf/httpd.conf <<EOF
#######
ServerName localhost:80
TraceEnable off
ServerTokens Prod
ServerSignature Off
EOF

##配置站点www.a.com，仅需将"web=www.a.com"修改成对应站点名称，运行以下脚本即可创建虚拟主机以及相应的目录。
web=www.a.com
mkdir -p /www/$web

cat >>/usr/local/apache/conf/httpd.conf <<EOF
########
Include conf/conf.d/$web.conf
########
EOF

cat > /usr/local/apache/conf/conf.d/$web.conf <<EOF
<VirtualHost *:80>
DocumentRoot "/www/$web/"
ServerName   $web
ErrorLog "|/usr/local/apache/bin/rotatelogs   /usr/local/apache/logs/$web-%Y%m%d_error.log 86400 480"
CustomLog "|/usr/local/apache/bin/rotatelogs  /usr/local/apache/logs/$web-%Y%m%d_access.log 86400 480" common
</VirtualHost>
<Directory "/www/$web/">
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
DirectoryIndex index.php index.Html index.html
</Directory>
EOF

2.配置Resin，将Resin的web路径与Apache的web路径指向到同一个文件夹

cp /usr/local/resin/conf/resin.conf /usr/local/resin/conf/resin.conf.bak
sed -i "s#webapps/ROOT#/www/$web/#g" /usr/local/resin/conf/resin.conf

3.放置测试页面

cat > /www/www.a.com/index.jsp <<EOF
<HTML>
<HEAD>
<TITLE>Jsp Page</TITLE>
</HEAD>
<BODY>
<%out.println("<h1>Hello 51cto! This is jsp Page.</h1>");%>
</BODY>
</HTML>
EOF
cat > /www/www.a.com/index.html <<EOF
<h1>Hello 51cto! This is html<h1>
EOF

4.启动服务并测试连配效果

/usr/local/apache/bin/apachectl start
/usr/local/resin/bin/httpd.sh  start

修改客户机hosts做解析 192.168.175.100 www.a.com 访问www.a.com (索引页面是index.html)测试静态页面



访问www.a.com/index.jsp 测试jsp动态页面。

四、安装过程中遇到的问题及解决方法1.编译Resin出现bad apxs /usr/local/apache/bin/apxs出现原因：安装apache前未安装perl。所以apxs的第一行是 #!/replace/with/path/to/perl/interpreter -w解决方法：安装perl，然后修改apxs的第一行为#!/usr/bin/perl -w，完成之后重新编译resin

##安装prel
yum -y install perl

##备份apxs
cp /usr/local/apache/bin/apxs /usr/local/apache/bin/apxs_bak

##修改apxs
sed -i 's@#!/replace/with/path/to/perl/interpreter -w@#!/usr/bin/perl -w@g' /usr/local/apache/bin/apxs

2.编译Resin时出现error: apr_hooks.h: No such file or directory等报错

出现原因：编译完Apache后，apr、apr-util、pcre的C语言头文件没有包含在Apache目录中。解决方法：使用软连接将apr、apr-util、pcre的C语言头文件链到Apache的include目录中。

ln -s /usr/local/pcre/include/* /usr/local/apache/include/
ln -s /usr/local/apr/include/apr-1/* /usr/local/apache/include/
ln -s /usr/local/apr-util/include/apr-1/* /usr/local/apache/include/

3.编译完Resin后，apache的mod_caucho.so模块没有编译成功。

##编译过程报错信息
EGREP="/bin/grep -E" /usr/local/src/resin-3.1.14/libtool --silent --tag=CXX --mode=compile gcc -o mod_caucho.lo -c -I/usr/local/apache-2.4.20/include  -I/usr/local/apr/include/apr-1  -DRESIN_HOME=\"/usr/local/src/resin-3.1.14\" -I../common -g -O2 -DPOLL -DEPOLL -D_POSIX_PTHREAD_SEMANTICS -DB64 -DHAS_SOCK_TIMEOUT -DHAS_JVMTI   -DLINUX -D_REENTRANT -D_GNU_SOURCE  -g -O2 -pthread mod_caucho.c

mod_caucho.c: In function 'caucho_request':
mod_caucho.c:896: error: 'conn_rec' has no member named 'remote_ip'
make[2]: *** [mod_caucho.lo] Error 1

出现原因：Apache2.4中API发生了变化详见官方文档http://httpd.apache.org/docs/2.4/developer/new_api_2_4.html中conn_rec->remote_ip and conn_rec->remote_addr部分解决方式：修改mod_caucho.c中的api变量。将remote_ip改为client_ip，将remote_addr改为client_addr，然后重新编译Resin

sed -i 's/remote_ip/client_ip/g' /usr/local/src/resin-3.1.14/modules/c/src/apache2/mod_caucho.c
sed -i 's/remote_addr/client_addr/g' /usr/local/src/resin-3.1.14/modules/c/src/apache2/mod_caucho.c
