resion 学习笔记

resin是一个非常流行的web引用服务器，对servlet和jsp提供了良好的支持，自身采用java开发，支持集群，还支持PHP。

resin分为普通版和专业版，主要区别是专业版支持缓存和负载均衡。

一、配置安装

1、安装jdk

# tar -xf jdk-8-linux-x64.tar.gz -C /application/    
# ln -s  /application/jdk1.8.0_60   /application/jdk 

方法一、

# sed -i.ori '$a export JAVA_HOME=/application/jdk
export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tools.jar' /etc/profile

方法二、

# echo '#java env  config ' >>/etc/profile
# echo 'export JAVA_HOME=/application/jdk' >>/etc/profile
# echo 'export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib' >>/etc/profile
# echo 'export  PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin' >>/etc/profile
# echo 'export RESON_HOME=/application/resin' >>/etc/profile

生效及检查版本

# source /etc/profile 
# java -version

2、安装resin

# cd /home/nulige/tools/
# tar xf resin-3.1.13.tar.gz
# mv resin-3.1.13 /application/
# ln -s /application/resin-3.1.13/ /application/resin
# ls -l /application/resin/

3、配置resin 

# ls   /application/resin/conf
app-default.xml　development.conf　fine.conf　minimal.conf　resin.conf　resin.conf.orig 
# vim   /application/resin/conf/resin.conf

从88行开始删除到146行，（快整跳到88行，用快捷键：88gg) 再用快捷键:59dd (删除59行内容)

#再添加下面代码到删除的地方，并注意：server id= xxx,是指启动时指定的标签，地址就是本机网卡地址，端口不用改。

<http address="*" port="8080"/> #如果做web服务用，就把端口修改成80。

添加代码如下：

<!-- resin Configure  -->
<server id='oldboy' address='10.0.0.8' port='6911' watchdog-port="6921"> # 6911：真正resin端口，6921：watchdog端口
<http address="*" port="8080"/>   #8080：resin web server端口
<jvm-arg>-Xmx256m</jvm-arg>       #最大堆大小
<jvm-arg>-Xss1m</jvm-arg>         #初始堆大小，一般xmx和xss值是相同的，避免运行时内存不足，系统在内存申请的花销
<jvm-arg>-Xdebug</jvm-arg>
<jvm-arg>-Dcom.sun.management.jmxremote</jvm-arg>
<memory-free-min>1M</memory-free-min>        #当jvm的内存小于这个指定值，resin服务会gracefully重启，来释放泄露的内存空间
<thread-max>256</thread-max>
<socket-timeout>65s</socket-timeout>         #读写socket最大超时时间
<keepalive-max>128</keepalive-max>           #最大长连接数量
<keepalive-timeout>15s</keepalive-timeout>   #长连接超时时间
</server>

4、启动resin  

# /application/resin/bin/httpd.sh -server oldboy start
# netstat -lntup|egrep "6911|6921|8080"
tcp 0 0 :::8080 :::* LISTEN 2373/java 
tcp 0 0 ::ffff:192.168.1.139:6911 :::* LISTEN 2373/java 
tcp 0 0 ::ffff:127.0.0.1:6921 :::* LISTEN 2345/java
# ps -ef|grep java

5、配置站点目录

# cd   /application/resin/webapps/ROOT/
# echo '<99+1=<%=99+1>' >/application/resin/webapps/ROOT/test.jsp
# cat /application/resin/webapps/ROOT/test.jsp
# curl http://192.168.1.8:8080/test.jsp

6、配置启动方式

1）系统自带的启动脚本

# cp /application/resin/contrib/init.resin.in   /etc/init.d/resind
# chmod +x /etc/init.d/resind

2）自己写一个启动脚本,放在启动目录

resind启动脚本

#!/bin/sh
#chkconfig:345 85 15
#To install, configure this file as needed and copy init.resin
#to /etc/rc.d/init.d as resin. Then use "# /sbin/chkconfig resin reset"
. /etc/init.d/functions
StartPath='/application/resin/bin/httpd.sh'
ResinLog=/app/logs/resinlog
[ ! -d $ResinLog ] && mkdir -p &ResinLog

resind()

{
#如果是多进程增加下面的配置段：oldboy后面空格再接标签名即可
for id in oldboy
do
        $StartPath -server $id $1 >> $ResinLog/resin_startup.log
        if [ $? -eq 0 ]
        then
           action "$1 $id resin..."/bin/true
        else
           action "$1 $id resin..."/bin/false
        fi
done

}

case "$1" in
  start)
        resind $1
        echo '------checking-------'
        sleep 15
        netstat -lnt|egrep "80|69"
        echo '------check over------'
        ;;

stop)
        resind $1
        ;;

restart)
        resind stop
        resind start
        ;;

*)
        echo "Usage: $0{start|stop|restart}"
        exit 1
esac

exit 0

#dos2unix处理一下

# dos2unix  /home/tom/init.d/resind

# chmod +x /home/tom/init.d/resind

7、添加开机自启动

# chkconfig --add resind
# chkconfig resind on
# chkconfig --list resind
# echo “/home/tom/init.d/resind  start ” >>/etc/rc.local

 二、整合 appche + resin

1、安装appche

# yum -y install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel 
# ./configure --prefix=/application/apache2.2.23
--enable-deflate 
--enable-headers 
--enable-modules=so 
--enable-so 
--with-mpm=worker 
--enable-rewrite
# make && make install

2、为apache编译resin mod_caucho 模块

# cd /application/resin-3.1.13
# ./configure --with-apxs=/application/apache2.2.23/bin/apxs
# cd /application/resin/modules/c/src/
# make  && make install
# ls -l  /application/apache/modules/
mod_caucho.so
提示：这个模块很类似Apache+php结合的PHP模块一样，Apache就是通过这个mod_caucho.so模块调用resin解析Java程序的

# tail -9 /application/apache/conf/httpd.conf
#mod_caucho Resin Configuration
LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so
ResinConfigServer 192.168.1.8 6911
CauchoConfigCacheDirectory /tmp 
CauchoStatus yes

3、测试

echo "apache"         /var/www/a.html
echo "<%resin=99+1%>" /application/resin/webapps/ROOT/a.jsp    
curl http://192.168.1.8/a.html
curl http://192.168.1.8/a.jsp

默认情况：

Apache：解析静态网页，resin：解析动态网页
# vim /application/apache/conf/httpd.conf 到结尾，修改内容
ResinConfigServer 192.168.1.8 6921
SetHandler caucho-reques
SetHandler caucho-reques是转发作用，由Apache把所有的请求转给resin。

三、Apache虚拟主机+resin

1、配置虚拟主机

# cd /application/apache/conf/extra/
# vim  httpd-vhosts.conf
<VirtualHost *:80>
    DocumentRoot "/var/www"
    DirectoryIndex index.html index.jsp index.php
    ServerName www.abc.com
    ErrorLog  "logs/abc-error_log"
    CustomLog "logs/abc-access_log" common
    
    <Directory "/var/www">
    Options -Indexes +FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
    </Directory>
#Resin Configuration
ResinConfigServer 192.168.1.8 6921    
</ViretualHost>

2、修改Apache主配置文件内容：

# vim /application/apache/conf/httpd.conf
395  # Virtual hosts
396  Include conf/extra/httpd-vhosts.conf     ---此行注释要打开

# tail -9 /application/apache/conf/httpd.conf
#mod_caucho Resin Configuration
LoadModule caucho_module /application/apache2.2.23/modules/mod_caucho.so
#ResinConfigServer 192.168.1.8 6911           ---这里注释掉！
#SetHandler caucho-request
CauchoConfigCacheDirectory /tmp
CauchoStatus yes

 3、测试

# echo "Apache"  >/var/www/a.html
# echo "<%Apache=99+1%>"  >/var/www/a.jspApache
# echo "<%resin=99+1%>"  >/application/resin/webapps/ROOT/a.jsp
# curl www.abc.com/a.html
Apache
# curl www.abc.com/a.jsp
resin=100

四、Apache多虚拟主机+ resin多虚拟主机

1、配置Apache虚拟主机

# cat /application/apache/conf/extra/httpd-vhosts.conf
NameVirtualHost *:80
<VirtualHost *:80>
    DocumentRoot    "/var/www"
    DirectoryIndex  index.html index.php index.jsp
    ServerName      www.abc.com
    ErrorLog        "logs/abc-error_log"
    CustomLog       "logs/abc-access_log" common
 
   <Directory "/var/www">
   Options -Indexes  FollowSymLinks
   AllowOverride None
   Order allow,deny
   Allow from all
   </Directory>
#Resin Configuration
ResinConfigServer 192.168.1.140 6911
SetHandler caucho-request
</VirtualHost>
###########################
<VirtualHost *:80>
    DocumentRoot    "/var/blog"
    DirectoryIndex   index.html index.php index.jsp
    ServerName       www.abc.org
    ErrorLog         "logs/org-error_log"
    CustomLog        "logs/org-access_log" common
 
   <Directory "/var/blog">
   Options -Indexes  FollowSymLinks
   AllowOverride None
   Order allow,deny
   Allow from all
   </Directory>
#Resin Configuration
ResinConfigServer 192.168.1.140 6912
#SetHandler caucho-request
</VirtualHost>

2、配置resin多虚拟机

配置主配置     /application/resin/conf/resin.conf 

<!-- resin Configure at 2018-1-11 -->
<server id='abc' address='192.168.1.8' port='6911' watchdog-port="6921">
#   <http address="*" port="8080"/>
    <jvm-arg>-Xmx256m</jvm-arg>
    <jvm-arg>-Xss1m</jvm-arg>
    <jvm-arg>-Xdebug</jvm-arg>
    <jvm-arg>-Dcom.sun.management.jmxremote</jvm-arg>
    <memory-free-min>1M</memory-free-min>
    <thread-max>256</thread-max>
    <socket-timeout>65s</socket-timeout>
    <keepalive-max>128</keepalive-max>
    <keepalive-timeout>15s</keepalive-timeout>
    </server>

       <stdout-log path='/app/log/resinlog/blog_stdout.log'
                   rollover-period='1W'/>
     </host>

注释掉resin主配置中虚拟主机中的http端口内容：
90      <!-- <http address="*" port="8080"/> -->
104     <!-- <http address="*" port="8081"/> -->

3、测试

# echo "<%com=99+1%>"   /application/resin/webapps/ROOT/a.jsp
# echo "www.abc.com"    /application/resin/webapps/ROOT/a.html
# echo "<%org=99+1%>"   /application/resin/webapps/org/a.jsp
# echo "www.abc.org"    /application/resin/webapps/ROOT/a.html
# echo "<%com=99-1%>"   /var/www/a.jsp
# echo "apache www"     /var/www/a.html
# echo "<%com=99-1%>"   /var/blog/a.jsp
# echo "apache blog"    /var/blog/a.html
# curl www.abc.cc/a.jsp
com=100
# curl www.abc.cc/a.html
www.abc.com
# curl www.abc.org/a.jsp
org=100
# curl www.abc.org/a.html
