MongoDB Common Command Scripting-automated OPS writes the MONGODB commands commonly used in operations into shell scripts, greatly facilitates maintenance 1 set replica set #!/bin/bash
#mongodb Enter the client and use admin
Cd/usr/mongodb/bin
Mongodb= './mongo 192.168.1.7:37017 '
$MongoDB <<eof
Use admin
rsconf={
"_id": "Job001",
"Members": [
{
"_id": 0,
"Host": "192.168.1.7:37017"
}
]
}
Rs.initiate (rsconf)
Rs.add ("192.168.1.8:37017")
Rs.add ("192.168.1.9:37017")
Exit
Eof
Note: Write the above content to the ***.sh file chmod 777 ***.sh Assign permissions
These commands can be completed in Linux > sh ***.sh

2 Modifying the settings of a replica set
#!/bin/bash
#mongodb Enter the client and enter primary
Cd/usr/mongodb/bin
Mongodb= './mongo 192.168.1.7:37017 '
$MongoDB <<eof
Use Mongomodeljobresume
#rs. Status ()
Cfg=rs.conf ()
cfg.members[0].priority=99
Cfg.members[1].priority=50
Cfg.members[2].priority=30
Rs.reconfig (CFG)
Rs.conf ()
Exit
Eof
3 Turn a table to a temporary table and copy it back so that the full log is regenerated in the Oplog
(If the size of the oplog is large enough)
#!/bin/bash
#mongodb Enter the client and enter primary
Cd/usr/mongodb/bin
Mongodb= './mongo 192.168.1.7:37017 '
$MongoDB <<eof
Use Mongomodeljobresume
Rs.remove ("192.168.1.8:37017")
Rs.remove ("192.168.1.9:37017")
Db.tbJobResume.renameCollection ("Tbjobresumeold")
Db.tbJobResumeOld.copyTo ("Tbjobresume")
Rs.add ("192.168.1.8:37017")
Rs.add ("192.168.1.9:37017")
#db. Tbjobresumeold.drop ()
Exit
Eof
4 MongoDB Log by date MongoDB log default write in a file, time is long to view and so inconvenient, with cron scheduling task + script can be implemented by date log# rotatelog.sh generate this file with the following content chmod 777 rotelog.sh granting Permission #!/bin/bash
#mongodb Client Use Admin
Cd/usr/mongodb/bin
Mongodb= './mongo 192.168.1.7:37017 '
$MongoDB <<eof
Use admin
Db.runcommand ({logrotate:1})
Exit
EOF then opens with Crontab-e (no new) to add the following and save (the file path in/var/spool/cron/root/) * * */bin/sh/usr/mongodb/config/rotatelog.sh In this case, every night 23:59, the day's diary will be a * * * date. Log to save the original log file will be emptied 5 MongoDB database automatic backup Restore script
-----automatically back up MongoDB data and compress---
#!/bin/bash
Filename= ' Date +%y%m%d%h '
Backmongodbfile=mongodb$filename.tar.gz
cd/home/mongo/back/
/usr/mongodb/bin/mongodump-h 192.168.1.7-port 37017-d Mongodbagent-o mongodb_dump/
/usr/mongodb/bin/mongodump-h 192.168.1.7-port 37017-d Mongodbbg-o mongodb_dump/
/usr/mongodb/bin/mongodump-h 192.168.1.7-port 37017-d Mongomodelactor-o mongodb_dump/
Tar czf $backmongodbFile mongodb_dump/
RM MONGODB_DUMP-RF
-----automatically unzip and restore MONGODB data---
#!/bin/bash
Filename= ' 20150330013 '
Backmongodbfile=mongodb$filename.tar.gz
cd/home/mongo/back/
Tar zxvf $backmongodbFile
