=====Overview===== So, if we want to add existing server, under the wing of MongoOps Manager, we have to do the following: - Download & Install the RPM on the - Configure the agents with the MongoOps using ApiKey and Endpoint URL That is that. After that, we will be able to install whatever we want from the MongoOps manager. So let's get started: =====Download & Install===== In fact, when you go to MongoOps -> All clusters -> Agents -> Download & Settings, there is a easy way how to do the steps. Just follow them :) [root@dbpahfgcl ~]# curl -OL http://secretMongoOpsUrl:8080/download/agent/automation/mongodb-mms-automation-agent-manager-10.2.18.5978-1.x86_64.rhel7.rpm % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 13.5M 0 13.5M 0 0 208M 0 --:--:-- --:--:-- --:--:-- 211M [root@dbpahfgcl ~]# [root@dbpahfgcl ~]# [root@dbpahfgcl ~]# rpm -U mongodb-mms-automation-agent-manager-10.2.18.5978-1.x86_64.rhel7.rpm [root@dbpahfgcl ~]# You see, wasn't so hard :) Now for the tricky part. =====Configure the Agent===== To configure the agent we need: * GroupId * ApiKey * MongoOps URL In my case they are: * Secret * Secret * and Secret You have to configure them in: /etc/mongodb-mms/automation-agent.config =====Start===== Once all this is done, we can start the agent as follows: [root@dbpahfgcl ~]# vi /etc/mongodb-mms/automation-agent.config [root@dbpahfgcl ~]# chown mongod:mongod /data [root@dbpahfgcl ~]# systemctl start mongodb-mms-automation-agent.service [root@dbpahfgcl ~]# systemctl status mongodb-mms-automation-agent.service ● mongodb-mms-automation-agent.service - MongoDB MMS Automation Agent Loaded: loaded (/etc/systemd/system/mongodb-mms-automation-agent.service; disabled; vendor preset: disabled) Active: active (running) since Wed 2020-07-01 10:33:30 EDT; 4s ago Process: 5759 ExecStartPre=/usr/bin/chown -R mongod:mongod /var/run/mongodb-mms-automation (code=exited, status=0/SUCCESS) Process: 5757 ExecStartPre=/usr/bin/mkdir /var/run/mongodb-mms-automation (code=exited, status=0/SUCCESS) Main PID: 5762 (mongodb-mms-aut) CGroup: /system.slice/mongodb-mms-automation-agent.service └─5762 /opt/mongodb-mms-automation/bin/mongodb-mms-automation-agent -f /etc/mongodb-mms/automation-agen...

[root@dbpahfgcl ~]# =====Configure Replication Set===== That easily can be done from the MongoOps manager, but before you do, be sure to install the required packages: [root@dbpaifgcl ~]# yum -y install cyrus-sasl cyrus-sasl-gssapi cyrus-sasl-plain krb5-libs libcurl libpcap lm_sensors-libs net-snmp net-snmp-agent-libs openldap openssl rpm-libs tcp_wrappers-libs Loaded plugins: product-id, search-disabled-repos, subscription-manager Package krb5-libs-1.15.1-46.el7.x86_64 already installed and latest version Package libcurl-7.29.0-57.el7.x86_64 already installed and latest version Package 14:libpcap-1.5.3-12.el7.x86_64 already installed and latest version Package openldap-2.4.44-21.el7_6.x86_64 already installed and latest version Package 1:openssl-1.0.2k-19.el7.x86_64 already installed and latest version Package rpm-libs-4.11.3-43.el7.x86_64 already installed and latest version Package tcp_wrappers-libs-7.6-77.el7.x86_64 already installed and latest version Resolving Dependencies --> Running transaction check ---> Package cyrus-sasl.x86_64 0:2.1.26-23.el7 will be installed ---> Package cyrus-sasl-gssapi.x86_64 0:2.1.26-23.el7 will be installed ---> Package cyrus-sasl-plain.x86_64 0:2.1.26-23.el7 will be installed ---> Package lm_sensors-libs.x86_64 0:3.4.0-8.20160601gitf9185e5.el7 will be installed ---> Package net-snmp.x86_64 1:5.7.2-48.el7_8.1 will be installed --> Processing Dependency: net-snmp-libs = 1:5.7.2-48.el7_8.1 for package: 1:net-snmp-5.7.2-48.el7_8.1.x86_64 --> Processing Dependency: perl(Data::Dumper) for package: 1:net-snmp-5.7.2-48.el7_8.1.x86_64 --> Processing Dependency: libnetsnmp.so.31()(64bit) for package: 1:net-snmp-5.7.2-48.el7_8.1.x86_64 ---> Package net-snmp-agent-libs.x86_64 1:5.7.2-48.el7_8.1 will be installed --> Running transaction check ---> Package net-snmp-libs.x86_64 1:5.7.2-48.el7_8.1 will be installed ---> Package perl-Data-Dumper.x86_64 0:2.145-3.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ===================================================================================================================== Package Arch Version Repository Size ===================================================================================================================== Installing: cyrus-sasl x86_64 2.1.26-23.el7 rhel-7-server-rpms 88 k cyrus-sasl-gssapi x86_64 2.1.26-23.el7 rhel-7-server-rpms 41 k cyrus-sasl-plain x86_64 2.1.26-23.el7 rhel-7-server-rpms 39 k lm_sensors-libs x86_64 3.4.0-8.20160601gitf9185e5.el7 rhel-7-server-rpms 42 k net-snmp x86_64 1:5.7.2-48.el7_8.1 rhel-7-server-rpms 332 k net-snmp-agent-libs x86_64 1:5.7.2-48.el7_8.1 rhel-7-server-rpms 707 k Installing for dependencies: net-snmp-libs x86_64 1:5.7.2-48.el7_8.1 rhel-7-server-rpms 751 k perl-Data-Dumper x86_64 2.145-3.el7 rhel-7-server-rpms 47 k Transaction Summary ===================================================================================================================== Install 6 Packages (+2 Dependent packages) Total download size: 2.0 M Installed size: 6.2 M Downloading packages: (1/8): cyrus-sasl-2.1.26-23.el7.x86_64.rpm | 88 kB 00:00:00 (2/8): cyrus-sasl-gssapi-2.1.26-23.el7.x86_64.rpm | 41 kB 00:00:00 (3/8): cyrus-sasl-plain-2.1.26-23.el7.x86_64.rpm | 39 kB 00:00:00 (4/8): lm_sensors-libs-3.4.0-8.20160601gitf9185e5.el7.x86_64.rpm | 42 kB 00:00:00 (5/8): net-snmp-5.7.2-48.el7_8.1.x86_64.rpm | 332 kB 00:00:00 (6/8): net-snmp-agent-libs-5.7.2-48.el7_8.1.x86_64.rpm | 707 kB 00:00:00 (7/8): net-snmp-libs-5.7.2-48.el7_8.1.x86_64.rpm | 751 kB 00:00:00 (8/8): perl-Data-Dumper-2.145-3.el7.x86_64.rpm | 47 kB 00:00:00 --------------------------------------------------------------------------------------------------------------------- Total 1.1 MB/s | 2.0 MB 00:00:01 Running transaction check Running transaction test Transaction test succeeded Running transaction Warning: RPMDB altered outside of yum.
