shell脚本安装rocketmq主从样例教程

自定义参数

ROCKETMQ_NAME= #服务全名
ROCKETMQ_PATH= #安装路径
TEMP_PATH= #临时目录
USER_NAME= #启动用户

部署参数检查

#!/bin/bash

# 检查参数是否设置
echo "=====检查参数是否设置====="
if [ ! $ROCKETMQ_PATH ];then
    echo "=====$ROCKETMQ_PATH 此参数未设置，请检查！====="
    exit 1
fi

if [ ! $ROCKETMQ_NAME ];then
    echo "=====$ROCKETMQ_NAME 此参数未设置，请检查！====="
    exit 1
fi

isServerExist=$(ps -ef | grep $ROCKETMQ_NAME | grep -v grep | awk '{print $2}' | wc -l)

# 检查服务是否已经安装
echo "=====检查服务是否已经安装====="
if [ "${isServerExist}" != "0" ]; then
    echo "$ROCKETMQ_NAME 服务已启动，请先卸载"  
    exit 1
else
    echo "$ROCKETMQ_NAME 服务未启动，符合预期！" 
fi

# 检查目标目录是否存在
echo "=====检查目标目录是否存在====="
if [ ! -d $ROCKETMQ_PATH ];then
    echo "=====$ROCKETMQ_PATH 目录不存在，创建目录====="
    mkdir -p $ROCKETMQ_PATH
fi

 echo "=====部署前检查通过====="
 

上传并解压安装包

#!/bin/bash
pwd

# 解压安装包到指定目录
echo "=====解压安装包到指定目录====="
unzip -o ${ROCKETMQ_NAME}.zip -d $ROCKETMQ_PATH
echo "=====查看解压后的内容====="
ls $ROCKETMQ_PATH/$ROCKETMQ_NAME

验证服务

        if [ "$ISSTART" -ge "8" ]; then
            echo "发现服务进程，为确保服务真正启动成功，等待15秒后进行第二次判断！"
                sleep 15
                ISSTART=$(ps -ef | grep $ROCKETMQ_NAME | grep -v grep | awk '{print $2}' | wc -l)
                if [ "$ISSTART" -ge "8" ]; then
                    echo "等待15秒后端口仍存活，服务第二次判断通过，服务启动成功！"
                    exit 0
                else
                    echo "等待15秒后端口未找到，服务第二次判断失败，服务启动失败！"
                    exit 1
                fi
        else
            echo "服务启动中，请等待！"
        fi
    done

清理临时目录安装包

rm -rf ${TEMP_PATH}
mkdir -p ${TEMP_PATH}
