Dubbo基础篇--在Linux操作系统上手工部署Dubbo服务

部署到edu-provider-01(192.168.1.121)

一、环境变量配置

[root@edu-provider-01 ~]# ln -s /usr/Java/jdk1.7.0_45/ /usr/jdk
[root@edu-provider-01 ~]# vi /etc/profile

JAVA_HOME=/usr/jdk

PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH

[root@edu-provider-01 ~]# java -version

[root@edu-provider-01 ~]#

[root@edu-provider-01 ~]# source /etc/profile

[root@edu-provider-01 ~]# cd /home/yxq
[root@edu-provider-01 ~]# mkdir edu
[root@edu-provider-01 ~]# cd edu
[root@edu-provider-01 edu]# mkdir app
[root@edu-provider-01 edu]# mkdir serivce
[root@edu-provider-01 edu]# mkdir timer
[root@edu-provider-01 edu]# mkdir web
[root@edu-provider-01 edu]# cd serivce/
[root@edu-provider-01 serivce]# mkdir user

2.目录规范

要避免应用迁移时路径冲突

[root@edu-provider-01 serivce]# ls
user
[root@edu-provider-01 serivce]# cd user
[root@edu-provider-01 user]# ls
edu-service-user.jar  lib  service-user.sh
[root@edu-provider-01 user]# chmod 777 service-user.sh 
[root@edu-provider-01 user]# ./service-user.sh start
=== start edu-service-user
[root@edu-provider-01 user]# 

停止、重启服务

[root@edu-provider-01 user]# ./service-user.sh stop
=== stop edu-service-user
=== edu-service-user process not exists or stop success
[root@edu-provider-01 user]# ./service-user.sh restart
cat: /home/yxq/edu/serivce/user/edu-service-user.pid: No such file or directory
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
=== stop edu-service-user
=== edu-service-user process not exists or stop success
=== start edu-service-user
=== restart edu-service-user
[root@edu-provider-01 user]# 

service-user.sh脚本

 #!/bin/sh

 ## java env
 export JAVA_HOME=/usr/local/java/jdk1.7.0_72
 export JRE_HOME=$JAVA_HOME/jre

 ## service name
 APP_NAME=user

 SERVICE_DIR=/home/wusc/edu/service/$APP_NAME
 SERVICE_NAME=edu-service-$APP_NAME
 JAR_NAME=$SERVICE_NAME\.jar
 PID=$SERVICE_NAME\.pid

 cd $SERVICE_DIR

 case "$1" in

     start)
         nohup $JRE_HOME/bin/java -Xms256m -Xmx512m -jar $JAR_NAME >/dev/null 2>&1 &
         echo $! > $SERVICE_DIR/$PID
         echo "=== start $SERVICE_NAME"
         ;;

     stop)
         kill `cat $SERVICE_DIR/$PID`
         rm -rf $SERVICE_DIR/$PID
         echo "=== stop $SERVICE_NAME"

         sleep 5
         ##
         ## edu-service-aa.jar
         ## edu-service-aa-bb.jar
         P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'`
         if [ "$P_ID" == "" ]; then
             echo "=== $SERVICE_NAME process not exists or stop success"
         else
             echo "=== $SERVICE_NAME process pid is:$P_ID"
             echo "=== begin kill $SERVICE_NAME process, pid is:$P_ID"
             kill -9 $P_ID
         fi
         ;;

     restart)
         $0 stop
         sleep 2
         $0 start
         echo "=== restart $SERVICE_NAME"
         ;;

     *)
         ## restart
         $0 stop
         sleep 2
         $0 start
         ;;

 esac
 exit 0

3.自定义Dubbo服务维护的Shell脚本

脚本命名规范

/hom/yxq/edu/service/xxx/service-xxx.sh

例如:

/home/yxq/edu/serivce/user/service-user.sh

效果

./service-user.sh start

./service-user.sh stop

./service-user.sh restart

5.手动维护注意事项(结合自定义的Shell脚本)

(1)脚本规范--尽可能通用

(2)守护进程

(3)内存调优设置--按需调整

(4)日志处理--只保留应用log4j输出的日志

(5).避免服务冲突--进程名、端口

(6)避免进程误杀--全匹配
