Linux日常巡检脚本

关于linux环境的日常操作，我分享一点经验。

对于linux系统的日常监控运维，无非是一些内存、cpu、文件空间、进程、端口等等，一些列的运维，这些都可以通过简单的linux命令进行解决。

通过撰写shell脚本，对环境进行运维，一下简单介绍几种：

1.文件的操作

将文件放到远程机器	将远程文件达到本地	将远程文件删除
ftpPutFiles(){ remoteHost=$1 ftpUser=$2 ftpPwd=$3 remoteDir=$4 localDir=$5 localFiles=$6 ftp -i -v -n $remoteHost < user $ftpUser $ftpPwd binary lcd $localDir cd $remoteDir mput $localFiles bye END_FTP (sleep 2; echo $ftpUser;  sleep 2; echo $ftpPwd;  sleep 2; echo "chmod a+rwx $remoteDir/$localFiles";  sleep 2; echo "exit") | telnet $remoteHost 2>&1 | grep -v "getwinsize" }	ftpGetFiles(){ remoteHost=$1 ftpUser=$2 ftpPwd=$3 remoteDir=$4 remoteFiles=$5 localDir=$6 ftp -i -v -n $remoteHost < user $ftpUser $ftpPwd binary lcd $localDir cd $remoteDir mget $remoteFiles bye END_FTP }	ftpDelFiles(){ remoteHost=$1 ftpUser=$2 ftpPwd=$3 remoteDir=$4 remoteFiles=$5 ftp -i -v -n $remoteHost < user $ftpUser $ftpPwd binary cd $remoteDir mdel $remoteFiles bye END_FTP }

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2.文件系统的检查脚本

checkFileSystem(){    REMOTE_HOST=$1    REMOTE_USER=$2    REMOTE_PWD=$3    FILE_SYSTEM_LOG=fileSystem.log    (sleep 1; echo $REMOTE_USER;     sleep 1; echo $REMOTE_PWD;     sleep 1; echo "df -h|grep %|awk '{print \$(NF-1),\$NF}'|awk -F '%' '{if (\$1 > 80) {print \"$REMOTE_HOST\",\$1\"%\",\$2}}'>$FILE_SYSTEM_LOG";     sleep 1; echo "exit") | telnet $REMOTE_HOST 2>&1 | grep -v "getwinsize" >tmp.out    ftpGetFiles $REMOTE_HOST $REMOTE_USER $REMOTE_PWD /home/$REMOTE_USER $FILE_SYSTEM_LOG . >/dev/null    ftpDelFiles $REMOTE_HOST $REMOTE_USER $REMOTE_PWD /home/$REMOTE_USER $FILE_SYSTEM_LOG >/dev/null    cat $FILE_SYSTEM_LOG >> $LOG_FILE    rm $FILE_SYSTEM_LOG }

 

 

 

 

 

 

 

 

 

 

 

3.进程端口的检查

checkRabbitMq(){ REMOTE_HOST=$1 REMOTE_USER=$2 REMOTE_PWD=$3 CHECK_MQ_SCRIPTS=checkMQ.sh echo "oldIfs=\$IFS; IFS=':' processNums=\`ps -ef | grep rabbitmq | grep -v grep | wc -l \` if [ \$processNums -eq 1 ]; then echo \"hostname:\" \`hostname\` ,\"RabbitMq,process status:true\" else echo \"hostname:\" \`hostname\`,\"RabbitMq,process status:false\" fi IFS=\$oldIfs">>$CHECK_MQ_SCRIPTS ftpPutFiles $REMOTE_HOST $REMOTE_USER $REMOTE_PWD /home/$REMOTE_USER . $CHECK_MQ_SCRIPTS >/dev/null (sleep 1; echo $REMOTE_USER; sleep 1; echo $REMOTE_PWD; sleep 1; echo "sh $CHECK_MQ_SCRIPTS"; sleep 2; echo "rm $CHECK_MQ_SCRIPTS"; sleep 1; echo "exit") | telnet $REMOTE_HOST 2>&1 | grep -v "getwinsize" >tmp.out cat tmp.out |grep RabbitMq >>$LOG_FILE rm tmp.out }
