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 <<END_FTP
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 <<END_FTP
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 <<END_FTP
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
} |
