Linux 常用命令 1、批量壓縮文件 tar -cvf hj.tar.gz hmall-\*.log zip? -q? -r zbak\_goods\_202211.zip? goods-2022-11\*.log 2、磁盤目錄查詢 du -h --max-depth=1 3、大文件切割 log='tail -n 1000 nohup.out' echo "$log" > nohup.out 4、阿里云部署失敗 systemctl restart aliyun.service 或 /home/staragent/bin/staragentctl status /home/staragent/bin/staragentctl restart 5、#jar 啟動命令 nohup java -jar? hjmall-conifg-admin-1.0-SNAPSHOT.jar? ? >/dev/null 2>&1 & #jar批量啟動 sed -i 's/\\r$//' [java.sh](http://java.sh)? ? ///bin/bash^M: 壞的解釋器: 沒有那個文件或目錄 chmod +7 [java.sh](http://java.sh)? //-bash: ./java.sh: 權限不夠 6、生成普通的jar包 mvn clean package -D spring-boot.repackage.skip=true springboot? 多模塊項目父項目不要用spring-boot-maven-plugin 7、Kafka啟動 單機：? ? /usr/local/kafka/kafka\_2.11-2.3.1 啟動 ：在/usr/local/kafka/kafka\_2.11-2.3.1目錄下 1、bin/zookeeper-server-start.sh -daemon config/zookeeper.properties 2、bin/kafka-server-start.sh? -daemon? ? config/server.properties 集群： /usr/local/kafka/kafka01/bin/zookeeper-server-start.sh? /usr/local/kafka/kafka01/config/zookeeper.properties >/dev/null 2>&1 & /usr/local/kafka/kafka02/bin/zookeeper-server-start.sh? /usr/local/kafka/kafka02/config/zookeeper.properties >/dev/null 2>&1 & /usr/local/kafka/kafka01/bin/kafka-server-start.sh? ? /usr/local/kafka/kafka01/config/server.properties 2>&1 & /usr/local/kafka/kafka02/bin/kafka-server-start.sh? ? /usr/local/kafka/kafka02/config/server.properties 2>&1 & 8、redis 啟動 win:? ? redis-server redis.windows.conf linux ：nohup? ./redis-server? /usr/redis/redis-5.0.5/redis.conf? & 停止命令ps? -ef|grep? redis? ? ? kill -9? 進程Id 9、啟動nginx ①? 進入sbin文件? ? 命令：./nginx ②? ? /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf 10、nacos /usr/local/nacos/nacos 啟動：sh [startup.sh](http://startup.sh) -m standalone 11、nexus cd /usr/local/nexus/nexus-3.9.0-01/bin ./nexus start 重啟 ./nexus restart? 重啟服務 12、tail: inotify cannot be used, reverting to polling: Too many open files 處理方法： 在 /etc/sysctl.conf文件中加入下面的配置： fs.inotify.max\_user\_watches=1048576 fs.inotify.max\_user\_instances=1048576 sysctl -p /etc/sysctl.conf 使修改生效。再次執行 tail -f catalina.out 就可以了。 13、RocketMQ \# 1啟動nameserver nohup sh bin/mqnamesrv & \# 查看nameserver日志 tail -f ~/logs/rocketmqlogs/namesrv.log \# 2啟動broker nohup sh bin/mqbroker -n 127.0.0.1:9876 -c conf/broker.conf autoCreateTopicEnable=true & \# 查看broker日志 tail -f ~/logs/rocketmqlogs/broker.log
