  • Docker pull error: Invalid registry endpoint https on Centos 7.1

    Error: docker pull does not work on insecure connection by default

    Solution for Centos 7: Add –insecure-registry option

    1. Edit /lib/systemd/system/docker.service:

    [Unit]
    Description=Docker Application Container Engine
    Documentation=https://docs.docker.com
    After=network.target docker.socket
    Requires=docker.socket

    [Service]
    EnvironmentFile=-/etc/sysconfig/docker
    Type=notify
    ExecStart=/usr/bin/docker daemon $other_args -H fd://
    MountFlags=slave
    LimitNOFILE=1048576
    LimitNPROC=1048576
    LimitCORE=infinity

    [Install]
    WantedBy=multi-user.target

    2. Edit /etc/sysconfig/docker

    other_args=”–insecure-registry registry_ip:port“

    3. Restart docker daemon:

    sudo systemctl daemon-reload
    sudo service docker restart

  • MongoDB error local.oplog.rs is not empty on the initiating member. cannot initiate

    Error when initiating replica set with some old data in local database:

    rs.initiate() 
{
"errmsg" : "local.oplog.rs is not empty on the initiating member. cannot initiate.",

  • MongoDB replSet error loading set config (BADCONFIG)

    Error when initiate replicaset in MongoDB:

    “errmsg” : “replSet error loading set config (BADCONFIG)”, “ok” : 0 }

    Solution:

    1. Stop mongod, delete all local.* files in DBPath, start mongod or delete database local directly in mongo shell:

    use local
db.dropDatabase()

    2. Reconfigure replica set members:

    config = {_id: “repl1”, members:[

    {_id: 0, host: ‘192.168.2.1:27017′},

    {_id: 1, host: ‘192.168.2.2:27017’}]

    }

     

    rs.reconfig(config, {force: true})

  • ERROR: http://rubygems.org/ does not appear to be a repository Error fetching remote data: Errno::ETIMEDOUT

    Error happens when installing gem package using proxy

    $ gem install sass
    ERROR: http://rubygems.org/ does not appear to be a repository
    Error fetching remote data: Errno::ETIMEDOUT: Connection timed out – connect(2) (http://rubygems.org/yaml)
    Falling back to local-only install
    ERROR: Could not find a valid gem ‘sass’ (>= 0) in any repository

    Solution:
    On RHEL/Centos:=, the variable http_proxy should have value started with ‘http://’

    Working:
    export http_proxy=http://192.168.1.1:3128

    Not working:
    export http_proxy=192.168.1.1:3128

    Or we can add proxy option in gem install command:
    gem install –http-proxy http://192.168.1.1:3128 sass

  • MongoDB MMS com.xgen.svc.brs.svc.DaemonAssignmentSvc: ERROR Assignment failed: No Daemon found with enough free space

    When adding new backup job to Mongo DB MMS, we can have this error
    com.xgen.svc.brs.svc.DaemonAssignmentSvc: ERROR Assignment failed: No Daemon found with enough free space

    But checking the storage, the usage is just under 20%.

    Solution: MMS requires manually configure the backup daemon when you add a new backup job to an existing one. Go to MMS Admin -> Backup -> Jobs -> Set binding, click on it and forces choosing the daemon in select list.

  • MongoDB Ops Manager Insufficient oplog size: The oplog window must be at least 3 hours over the last 24 hours for all members of replica set

    When configuring MongoDB Ops Manager (MMS), MMS backup check the oplog of last 24 hours. If there is a oplog windows does not cover minimum 3 hours, Ops Manager will not allow you to continue the backup configuration:

    Insufficient oplog size: The oplog window must be at least 3 hours over the last 24 hours for all members of replica set . Please increase the oplog

    Solution: If the current oplog size is indeed insufficient for 3 normal hours operations for your application, increase its size following this guide: http://docs.mongodb.org/v3.0/tutorial/change-oplog-size/
    If it is the case that you just set up the DB and do an intensive insert, then you don’t need to increase the oplog. Wait for another 24 hours and try the backup configuration process again (https://jira.mongodb.org/browse/MMS-2374)

  • Error: EACCES, permission denied /usr/lib/node_modules/protractor/selenium with webdriver-manager start

    Error: EACCES, permission denied ‘/usr/lib/node_modules/protractor/selenium’

    Solution:
    npm global install by default use this /usr/lib/ which only allow root to execute.
    Check the permission /usr/lib/ and make sure you have ‘x’ permission for other users
