今天，在公司服务器上使用脚本远程启动flume：
#!/bin/sh
for ip in 10.153.140.253;
#for ip in 10.153.140.250 10.153.140.251 10.153.140.252 10.153.140.253 10.153.140.254 10.153.140.255;
do
ssh root@$ip "ps -ef | grep java | grep -v grep |cut -c 9-15 | xargs kill -9"
ssh root@$ip "rm -rf /usr/local/apache-flume-1.7.0-bin/lib/ttbrain-log-flume-sink-jar-with-dependencies.jar"
scp ./ttbrain-log-flume-sink-jar-with-dependencies.jar root@$ip":/usr/local/apache-flume-1.7.0-bin/lib/"
ssh root@$ip "nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/engine-api-log.conf -n agent1 >/dev/null 2>&1 &"
done
看脚本里倒数第二行，逻辑很简单，通过ssh root@$ip 的方式远程执行命令，但是会报如下错误：
scp_lib.sh: line 10: nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/engine-api-log.conf -n agent1 >/dev/null 2>&1 &: No such file or directory
后来，经过检查，使用下面的方式，成功：
#!/bin/sh
for ip in 10.153.140.253;
#for ip in 10.153.140.250 10.153.140.251 10.153.140.252 10.153.140.253 10.153.140.254 10.153.140.255;
do
ssh root@$ip "ps -ef | grep java | grep -v grep |cut -c 9-15 | xargs kill -9"
ssh root@$ip "rm -rf /usr/local/apache-flume-1.7.0-bin/lib/ttbrain-log-flume-sink-jar-with-dependencies.jar"
scp ./ttbrain-log-flume-sink-jar-with-dependencies.jar root@$ip":/usr/local/apache-flume-1.7.0-bin/lib/"
echo "nohup flume-ng agent -c /usr/local/apache-flume-1.7.0-bin/conf -f /usr/local/apache-flume-1.7.0-bin/conf/engine-api-log.conf -n agent1 >/dev/null 2>&1 &" | ssh -T $ip
done
