通过脚本来启动/关闭presto的服务端和客户端服务

• 需求

使用一个脚本来启动presto的server和cli服务，并支持关闭server服务
启动presto命令：launcher start
关闭presto命令：launcher stop
开启客户端命令：resto --server 192.168.130.111:8080 --catalog hive --schema ods_news
当然可以这样直接启动是有条件的，需要配置presto的环境变量

• vim /etc/profile

export PRESTO_SERVER_HOME=/data/apps/presto-server-0.236
export PRESTO_CLI_HOME=/data/apps/presto-cli-0.236

export PATH=$PATH:$PRESTO_SERVER_HOME/bin:$PRESTO_CLI_HOME

• presto_server_cli.sh

#!/bin/bash
# filename:presto_server_cli.sh
# autho:zxy
# date:2021-07-19
# PRESTO的路径
PRESTO_SERVER_HOME=/data/apps/presto-server-0.236
PRESTO_CLI_HOME=/data/apps/presto-cli-0.236
# 接受参数
CMD=$1

## 帮助函数
usage() {
    echo "usage:"
    echo "presto_server_cli.sh server/cli/stop"
    echo "description:"
    echo "      server:start presto_server"
    echo "      cli:start presto_cli"
	echo "      stop:stop presto_server"
    exit 0
}

if [ ${CMD} == "server" ];then
        # 启动presto的server服务
        launcher start
        ps -aux | grep PrestoServer
elif [ ${CMD} == "cli" ];then
		# 启动presto的客户端
        presto --server 192.168.130.111:8080 --catalog hive --schema ods_news
elif [ ${CMD} == "stop" ];then
		# 关闭presto的server服务
		launcher stop
		ps -aux | grep PrestoServer
else
        usage
fi
