Previously-mentioned package install via yum installs the software
Configuration is in /etc/my.cnf and /etc/my.cnf.d:

• Setting the datadir attribute to where database storage is to live is advisable, to separate it from /var/lib/mysql, which is where the socket is created
• Trying to symbolic-link /var/lib/mysql to some other location causes permissions quirks
• For some reason, /var/run/mariadb is sometimes not created - to remediate:

  mkdir /var/run/mariadb
  chown mysql:mysql /var/run/mariadb
  chmod 775 /var/run/mariadb
  chmod g+s /var/run/mariadb
  cd /var/run/mariadb ; chcon -t var_run_t .

• Make sure /var/lib/mysql has mysqld_db_t type, in the directory: chcon -t mysqld_db_t .

Previously-mentioned package install via yum installs the software Edit /etc/httpd/conf/httpd.conf:

• Set DocumentRoot to suitable location, ensure location exists and resides in suitable storage

Open firewall for Apache:

firewall-cmd --permanent --zone=public --add-port=80/tcp
firewall-cmd --reload

Perform the typical systemctl enable httpd and service httpd start for startup

Create the file /etc/yum.repos.d/influxdb.repo with this content:

[influxdb]
name = InfluxDB Repository - RHEL $releasever
baseurl = https://repos.influxdata.com/rhel/$releasever/$basearch/stable
enabled = 1
gpgcheck = 1
gpgkey = https://repos.influxdata.com/influxdb.key

… then, do a yum update and yum install influxdb
Open firewall for InfluxDB:

firewall-cmd --permanent --zone=public --add-port=8086/tcp
firewall-cmd --permanent --zone=public --add-port=8083/tcp
firewall-cmd --reload

Edit /etc/influxdb/influxdb.conf and:

• In the [http] section:
  • Set enabled = true
  • Change the bind = :8086 entry, if needed
  • Set unix-socket-enabled = true
  • Change bind-socket = value to /var/run/influxdb/influxdb.sock
• In the [udp] section:
  • Set enabled = true
  • Change the bind = :8089 entry, if needed

Ensure /var/run/influxdb and /var/lib/influxdb exist and are owned correctly

• For some reason, /var/run/influxdb is sometimes not created - to remediate:

  mkdir /var/run/influxdb
  chown influxdb:influxdb /var/run/influxdb
  chmod 775 /var/run/influxdb
  chmod g+s /var/run/influxdb
  cd /var/run/influxdb ; chcon -t var_run_t .

Remember to systemctl enable influxdb and service influxdb start
See: InfluxDB auth

Create the file /etc/yum.repos.d/grafana.repo with this content:

[grafana]
name=grafana
baseurl=https://packagecloud.io/grafana/stable/el/7/$basearch
repo_gpgcheck=1
enabled=1
gpgcheck=1
gpgkey=https://packagecloud.io/gpg.key https://grafanarel.s3.amazonaws.com/RPM-GPG-KEY-grafana
sslverify=1
sslcacert=/etc/pki/tls/certs/ca-bundle.crt

… then, do a yum update and yum install grafana
Open firewall for Grafana:

firewall-cmd --permanent --zone=public --add-port=3000/tcp
firewall-cmd --reload

Remember to systemctl enable grafana-server and service grafana-server start
Log in (default login is admin with password admin) and change password, add user(s)
Install the InfluxDB datasource plugin (find in plugins section, follow instructions)

Pull the Jenkins repository file and import its GPG key:

wget -O /etc/yum.repos.d/jenkins.repo http://pkg.jenkins.io/redhat-stable/jenkins.repo
rpm --import http://pkg.jenkins.io/redhat-stable/jenkins.io.key

… then, do a yum update and yum install jenkins
If the jenkins login isn't locked down off-server:

• Enable login for Jenkins with usermod -s /bin/bash jenkins
• Log in as jenkins and create SSH key with: ssh-keygen -t rsa

Otherwise:

• Create SSH key for jenkins from root: ssh-keygen -f id_rsa -C “jenkins@bluejay”

Open firewall for Jenkins:

firewall-cmd --permanent --zone=public --add-port=8080/tcp
firewall-cmd --reload

Remember to systemctl enable jenkins and service jenkins start
Log in (default login is admin with password admin) and change password, add user(s)

Get latest maven archive, example:

wget http://www-eu.apache.org/dist/maven/maven-3/3.5.3/binaries/apache-maven-3.5.3-bin.tar.gz

Extract to suitable location and sym-link to it (/usr/maven or /opt/maven)
Set environment variables in /etc/profile.d/maven.sh:

export M3_HOME=/usr/maven
export M2_HOME=${M3_HOME}
export PATH=${M3_HOME}/bin:${PATH}

… perform a source /etc/profile.d/maven.sh to get these in current shell.

• Perform basic installation, and add the jenkins/bluejay logins, OpenJDK, and Maven
  • Remember to make jenkins and bluejay login passwords non-expiring:

    chage -I -1 -m 0 -M 99999 -E -1 thelogin

• Create jenkins login SSH keys and populate on bluejay web server
• Populate Jenkins controller's jenkins login SSH key into bluejay login's authorized_keys
• Populate the central repository at /var/www/html/pub/eptrepo/jmeter and create SSL cert
  • Edit the create-rmi-keystore.sh script, changing the validity to 99999 and run to gen cert
  • Ensure cert file rmi_keystore.jks has same ownership/permissions/seattr as other files

If /opt happens to be an XFS filesystem, resizing can be done “live”. Otherwise, in order to unmount /opt to manipulate it, all processes holding files open on the filesystem have to be shut down, including:

/etc/init.d/opsware-agent stop
/etc/init.d/vasd stop
service postfix stop
service dbus stop

Edit /etc/nsswitch.conf to comment out lines with vas4 in them, then kill -HUP <pid-of-nss-process>

Perform the whole thing in reverse when /opt is resized
