Loading... 具体代码 用法 切换普通用户后在目录创建my_hadoop.sh,添加内容 ``` #!/bin/bash if [ $# -lt 1 ] then echo "No Args Input..." exit ; fi case $1 in "start") echo " =================== 启动 hadoop集群 ===================" echo " --------------- 启动 hdfs ---------------" ssh hadoop21 "/opt/module/hadoop-3.1.3/sbin/start-dfs.sh" echo " --------------- 启动 yarn ---------------" ssh hadoop22 "/opt/module/hadoop-3.1.3/sbin/start-yarn.sh" echo " --------------- 启动 历史服务器 ---------------" ssh hadoop11 "mapred --daemon start historyserver" ;; "stop") echo " =================== 关闭 hadoop集群 ===================" echo " --------------- 关闭 yarn ---------------" ssh hadoop22 "/opt/module/hadoop-3.1.3/sbin/stop-yarn.sh" echo " --------------- 关闭 hdfs ---------------" ssh hadoop21 "/opt/module/hadoop-3.1.3/sbin/stop-dfs.sh" echo " --------------- 停止 历史服务器 ---------------" ssh hadoop11 "mapred --daemon stop historyserver" ;; "restart") echo " =================== 重启 hadoop集群 ===================" echo " --------------- 关闭 yarn ---------------" ssh hadoop22 "/opt/module/hadoop-3.1.3/sbin/stop-yarn.sh" echo " --------------- 关闭 hdfs ---------------" ssh hadoop21 "/opt/module/hadoop-3.1.3/sbin/stop-dfs.sh" echo " --------------- 停止 历史服务器 ---------------" ssh hadoop11 "mapred --daemon stop historyserver" echo " --------------- 启动 hdfs ---------------" ssh hadoop21 "/opt/module/hadoop-3.1.3/sbin/start-dfs.sh" echo " --------------- 启动 yarn ---------------" ssh hadoop22 "/opt/module/hadoop-3.1.3/sbin/start-yarn.sh" echo " --------------- 启动 历史服务器 ---------------" ssh hadoop21 "mapred --daemon start historyserver" ;; *) echo "Input Args Error..." ;; esac ``` ## 添加权限 ``` sudo chmod +x ~/bin/my_hadoop.sh ``` ## 创建软连接 ``` sudo ln -s ~/bin/my_hadoop.sh /bin/my_hadoop ``` 最后修改：2024 年 01 月 24 日 © 允许规范转载 打赏 赞赏作者 赞 咱们谁跟谁，用不着～
