Connect to selected node via ssh:

Complex anydbver setups including multiple linux containers. The first container has a default name, others node1, node2.... You can connect to any node with ssh:

./anydbver ssh # connects to default node
./anydbver ssh node1

Specifying host names for nodes

In complex setups each node could have individual name. The name is specified as a linux hostname, could be used for ssh, replication source, ldap server name.

./anydbver deploy ps:5.6 hostname:ps0.percona.local node1 ps:5.6 hostname:ps1.percona.local leader:ps0
./anydbver ssh ps0
./anydbver ssh ps1.percona.local

Updating version information

anydbver stores lists of version for each database product in temporary files. You can update it with latest values by running:

./anydbver update

Container OS image

By default, containers are based on CentOS 7. Newer distributions are not supporting all old database versions, but you still can use CentOS 8, Oracle Enterprise linux 7 and 8 or Ubuntu 20.04 Focal Fossa:

./anydbver deploy \
  ps:5.7 os:el7 \
  node1 ps:5.7 os:el8 master:default \
  node2 ps:5.7 os:focal master:default \
  node3 ps:5.7 os:oel7 master:default \
  node4 ps:5.7 os:oel8 master:default \
  node5 ps:5.7 os:bionic master:default

for i in default node{1,2,3,4,5} ; do ./anydbver ssh $i grep PRETTY_NAME /etc/os-release ; done
PRETTY_NAME="CentOS Linux 7 (Core)"
PRETTY_NAME="CentOS Linux 8"
PRETTY_NAME="Ubuntu 20.04.2 LTS"
PRETTY_NAME="Oracle Linux Server 7.9"
PRETTY_NAME="Oracle Linux Server 8.3"
PRETTY_NAME="Ubuntu 18.04.5 LTS"

Default os could be changed with --os osname. Put it right after deploy keyword:

./anydbver deploy --os el8 ps node1 ps master:default

Default OS is not disabling explicit os specification:

./anydbver deploy --os el8 ps node1 ps master:default node2 os:el7 ps

Allows to install a specific version of:

  • Percona Server
  • Percona XtraDB Cluster
  • PMM Server and clients
  • Percona Server for MongoDB
  • Percona Distribution for PostgreSQL
  • Community Postgresql Server
  • K3S kubernetes distribution

Advanced Installation

If you are able to run LXD on your linux server, there is no need to run additional virtual machines. Anydbver can re-use your LXD installation and run without vagrant.

# Specify LXD profile. It's important on servers with shared lxd environment
# In order to use non-default storage or network you should create a profile:
lxc storage create $USER dir source=/home/$USER/lxc
lxc profile copy default $USER
# replace pool: "your_storage_name", e.g with above $USER suggestion put your unix username instead of your_storage_name
lxc profile edit $USER
# add LXD_PROFILE also to your .bashrc to avoid using default storage pool
export LXD_PROFILE=$USER

Clone the repository and configure default provider:

git clone https://github.com/ihanick/anydbver.git
cd anydbver
./anydbver configure provider:lxd
./anydbver update

Kubernetes, PMM

Nested containers support is required for PMM server and Kubernetes operators. If your current setup is not able to run k3s, check https://github.com/corneliusweig/kubernetes-lxd/blob/master/README-k3s.md for lxd

In addition kubernetes requires /etc/sysctl.conf:

vm.overcommit_memory = 1
vm.overcommit_ratio = 10000
kernel.panic = 10
kernel.panic_on_oops = 1

Multi-user LXD setup requires high values for sysctl user.max_inotify_watches like 64k or 100k instead of default 8k to prevent "Error: No space left on device" problem.

In order to prevent dns issues inside k8s containers: https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/ reply from unexpected source problem could be solved with loading br_netfilter module

modprobe br_netfilter
modprobe overlay

You may have problems with flannel using vxlan network. Enable host-gw instead, add to your .bashrc:

export K3S_FLANNEL_BACKEND=host-gw

LXD 4.10 incompatibility with K3S

LXD 4.10 breaks compabibility with K3S. LXD ignores net.netfilter.nf_conntrack_tcp_timeout_established value on the host and uses default 5 days instead of 86400 seconds required for K3S. You can downgrade it, but LXD looses all settings:

# assuming you have LXD 4.10, do not run these commands on previous versions:
snap remove lxd
snap install lxd --channel=4.9/stable
# remove old storage and re-create profile
sudo rm -rf /home/$USER/lxc/*
lxc storage create $USER dir source=/home/$USER/lxc
lxc profile create $USER
lxc profile device add $USER root disk type=disk pool=$USER path=/
lxc network create lxdbr0
lxc profile device add $USER eth0 nic name=eth0 network=lxdbr0 type=nic

Anydbver command line parameters structure

Huge number of anydbver parameters and parameters order could be confusing. ./anydbver deploy command is:

  • A list of node definitions
./anydbver deploy \
    node0 <what to install and how to setup on node0> \
    node1 <what to install and how to setup on node1>
  • You can omit a default node name (named default or node0)
./anydbver deploy \
          <what to install and how to setup on node0> \
    node1 <what to install and how to setup on node1>
  • You can't inject gaps in the node list, the following example finished with error, because only default and node1 nodes are created:
./anydbver deploy node2 percona-server:5.6
[WARNING]: Could not match supplied host pattern, ignoring: ihanick.node2
ERROR! Specified hosts and/or --limit does not match any hosts
  • Installation/setup parameters could be configurable: optionname:parameter. Usually it's a version, e.g. percona-server:5.7 or percona-server:5.7.31. Other parameters requires node name or host name:
./anydbver deploy \
          mysql:5.7 hostname:server0.example.com \
    node1 mysql:5.7 master:server0.example.com
  • Sometimes it's required to run multiple actions on the same host after configuring other hosts, you can repeat nodename name
./anydbver deploy \
          <what to install and how to setup on node0> \
    node1 <what to install and how to setup on node1> \
    node0 <stage 2 installation/setup steps on node0>
