This article mainly introduces the Gluster cluster high availability configuration and node addition and deletion example analysis, the article is very detailed, has a certain reference value, interested friends must read it!

1. Gluster high availability configuration 1. Gluster node service planning

IP address planning

# vi / etc/hosts200.192.100.101 glusternode1 # Node 1 address 200.192.100.102 glusternode2 # Node 2 address 200.192.100.100 glustervip # gluster Service address

Volume Bricks planning

Execute on node 1, node 2:

# mkdir / storage#mount / dev/vg01/lvstorage / storage2. Configure and install high availability

Install keepalived on node 1 and node 2:

# yum install keepalived#vi / etc/keepalived/keepalived.conf! Configuration File for keepalivedvrrp_script chk_gluster {script "/ etc/keepalived/check_gluster.sh" interval 2 global_defs {router_id LVS_DEVEL} vrrp_instance VI_1 {state MASTER # slave server to be changed to BACKUP interface eth0 virtual_router_id 101 Priority 100 # standby server priority should be lowered to advert_int 1 authentication {auth_type PASS auth_pass Pass2020wd} track_script {chk_gluster} virtual _ ipaddress {200.192.100.100 if 24}}: wq#vi / etcswap keepalivedbat checkbox gluster.shrunk bind bind bashnumbles $(netstat-lnupt | grep glusterd | wc-l) if [$num-eq 0] Then systemctl start glusterd gluster volume start storage force if [$(netstat-lnupt | grep glusterd | wc-l)-eq 0]; then systemctl stop keepalived fifi:wq# gives script permission chmod + x / etc/keepalived/check_gluster.sh3. Configure gluster distributed storage

Add Node 2: gluster peer probe glusternode2 to Node 1

Add Node 1: gluster peer probe glusternode1 to Node 2

View node status

Gluster peer status

Create a replication volume:

# create replication volume gluster volume create storage replica 2 glusternode1:/storage glusternode2:storage# boot volume storagegluster volume start storage# view volume status gluster volume status# view volume information gluster volume info storage4. Start high availability and mount volumes through gluster service addresses

Execute on node 1 and 2

Systemctl enable keepalivedsystemctl start keepalived

Mount-t glusterfs glustervip:/storage / home/data

Second, Gluster node fault handling 1. Suppose glusternode1 fails

View the service IP on glusternode2 has been elegant

Ip-a | grep 200.192.100.100gluster volume status # check the status and find that glusternode1 has been disconnected

Delete the node on the glusternode1

# remove brickgluster volume remove-brick iso replica 1 glusternode1:/storage forcegluster volume statusgluster peer statusgluster peer detach glusternode1 on glusternode1 # remove gluster peer statusgluster volume status from glusternode1 node

When the glusternode1 node fault repair is completed, add the node back to

Gluster peer probe glusternode1 # add Node gluster peer status# add Node brick back to gluster volume add-brick iso replica 2 glusternode1:/storage forcegluster volume status above is all the content of the article "Gluster Cluster High availability configuration and sample Analysis of Node additions and deletions".
