Labs and Setup for 3.2 Talk
###Files and their purposes
| First Header | Second Header |
|---|---|
| fast_run.sh | Runs the following sub-commands to build a cluster in 3.0, then upgrade it to 3.2 with WiredTiger, new Replication Protocol and ReplicaSet based config servers |
| get_mongod_downloads.sh | Detects OSX vs Linux and download 3.0.11 and 3.2.4 into 3.0/ and 3.2/ folders inside them a bin folder exists with binaries |
| >build_procceses.sh | This build 2 replia-sets/shards with 3 members each, 3 config servers, and 1 mongos now and outputs their port ranges |
| >>config_replset.js | To build the replica sets this javascript code is called to initalise them |
| >populate_data_sharded_and_unsharded.sh | This is used to create a samples database with 2 collections where one is sharded and the other is not. Sharding and data creation are both done for you. |
| >>populate_fakedata.js | This is the functions the above code executes to preform those tasks |
| >make_secondaries_wt.sh | Takes r1-3 and r2-3 and rebuilds them as wiredTiger nodes but deleting their data, changing the startup to |
| use wired tiger, then resyncing | |
| >upgrade_all_to_3.2.4.sh | This upgrades all the binaries to 3.2 this is all replica nodes, config nodes, and mongos node |
| >upgrade_replica_proto_version.sh | This logs into r1 and r2 replicasets's primaries and then reconfigures them to allow the new |
| dumps and restoes 1 to make it wiredTiger and starts as replset also | |
| >>upgrade_replica_proto_version.js | This is the underlying code doing the reconfiguration |
| >upgrade_config_to_replicaset.sh | This is a bit of a cheat is kills all configs and the mongos, restarts 2&3 as replica members, dumps and restoes 1 to make it wiredTiger and starts as replset also |
| reset_lab.sh | Special code to cleanup your downloaded, dumped, and created folders allowing you to reset the lab to a refresh version |
| set_bin_dir.sh | Used by a few scripts to update config.conf , spefically the bin_dir and mongo_dbpath_root folder locations |
| config.conf | Stores the config so multiple scripts can jsut source it to make things cleaner |
This Lab is built to go with the Percona Live 2016 SJC Tutorial on MongoDB 3.2 - MongoDB 3.2: Getting the most out of it
##To Run Simple run ./fast_run.sh after cloning , or run the scripts manually based on the order above
##Known issues ###wger versions Some linux builds use wget 1.15 it has been found sometimes using https:// urls return 503 Service Unavailable, if this is the case replace https with http in get_mongod_downloads.sh
