The GlusterFS cluster automatically compiles and installs the configuration script.

To build a GlusterFS cluster and write an automated installation and configuration script, you only need to specify the IP address list of all nodes and the volume information you need to configure to compile, install, and deploy the entire cluster on one machine, remote Operations are completed through sshpass.

The script is simple. You need to enter the cluster information by yourself:

###############Initialization################PKG_PATH=/opt/files/glusterfs-3.4.0.tar.gzROOT_PASS=test# Gluster peersNODES=(192.168.64.87 192.168.64.88)# Gluster volumesvol_1=(nova_vol /opt/nova_vol 192.168.64.87,192.168.64.88)VOLUMES=(vol_1)#############################################

PKG_PATH is the installation package path

ROOT_PASS is the root password of each node (the password must be set to the same, and ssh connection is required for remote operations in the future)

NODES specifies the node IP address list of the cluster (separated by spaces)

Vol_1 specifies the volume information to be created, including the volume name (nova_vol), data path (/opt/nova_vol), and bricks IP address list (separated by commas ), you can enter multiple VOLUMES and specify the VOLUMES in VOLUMES.

After reading the cluster information, the script obtains the local address, decompress the source file, generate the local installation script, copy it to the/tmp directory of each node, and execute the script, modify the name of the decompressed directory and specify the name of the glusterFS software in the local installation script.

After the compilation and installation are complete, attach peers will be performed to create and start the volume. Please modify the parameters during the volume creation process.
