Java服务器-resin

安装jdk

[-----]#cd /home/qinbin/tools/
[-----]#chmod +x jdk-6u34-linux-x64.bin
[-----]#./jdk-6u34-linux-x64.bin
[-----]#mv jdk1.6.0_34/ /application/.
[-----]#cd /application/
[-----]#ll
[-----]#ln -s jdk1.6.0_34/ jdk
[-----]#cd
[-----]#vim /etc/profile
JAVA_HOME=/application/jdk
CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
RESIN_HOME=/application/resin
[-----]#source /etc/profile
[-----]#java
[-----]#javac

安装resin

01）安装resin并启动

[-----]#cd /home/qinbin/tools/
[-----]#tar xf resin-3.1.13.tar.gz
[-----]#ll
[-----]#mv  resin-3.1.13  /application/.
[-----]#cd  /application/
[-----]#ls
[-----]#ln -s resin-3.1.13/  resin
[-----]#ls
[-----]#mkdir -p /app/resinlog
[-----]#cd resin/conf
[-----]#ls
[-----]#vim resin.conf
<server-default>

<!-- define the servers in the cluster -->
<server id="qinbin" address="192.168.83.103" port="6911" watchdog-port="6921"/>
<server id="min" address="192.168.83.103" port="6931" watchdog-port="6941"/>
[-----]#killall java
[-----]#/application/resin/bin/httpd.sh -server qinbin/min start
[-----]# netstat -ntlup |egrep "8080|6911|6921"

02）resin和apache的整合
01.安装好apache
02.为apache编译resin的mod_caucho模块

[-----]#cd /application/resin
[-----]#./configure --with-apxs=/application/apache/bin/apxs
[-----]#cd /application/resin/modules/c/src/
[-----]#make
[-----]#make install
[root@qbPC conf]# ll /application/apache/modules/
httpd.exp      mod_caucho.so
（可以看见有mod_caucho.so，apache就是通过这个模块调用resin解析Java程序）

03.启动apache测试
/application/apache/bin/apachectl graceful
（可能会报错：error:httpd:arp_socked v_infor_get() faild from qb
解决：在/etc/hosts(127.0.0.1 localhost.localhost MYHOST)或者：将httpd.conf中的ServerName IP:80）
访问：curl 192.168.83.103
(报错：Service Temporarily Unavailable
解决：

[root@qbPC conf]# vim httpd.conf

LoadModule caucho_module /application/apache2.2.27/modules/mod_caucho.so

ResinConfigServer 192.168.83.103 6911
SetHandler caucho-request
#CauchoConfigCacheDirectory /tmp
#CauchoStatus yes

)

04.有关Java服务定时任务无法执行变量的问题

问题描述：

#crontab -e -n username
50 17 * * 1-5 root /usr/local/bin/resin_restart.sh
#resin_restart.sh
#!/bin/bash
/usr/local/bin/xxresin_stop.sh
/usr/local/bin/xxresin_start.sh

出现问题：服务器定时起来了，但是报错（Resin can't load com.sun.tools.java.Main）；

原因：由于export变量问题导致，crontab执行shell时只能执行为数不多的系统环境变量；

解决：在resin_restart.sh脚本中加入环境变量（JAVA_HOME/CLASSPATH/PATH/）,然后再export这些环境变量。
