Dubbo基础篇_05_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
CLASSPATH=$JAVA_HOME/lib/
PATH=$PATH:$JAVA_HOME/bin
export PATH JAVA_HOME CLASSPATH

[root@edu-provider-01 ~]# java -version
java version "1.7.0_45"

Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
[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

<span style="font-size:18px;">#!/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
</span>

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
