Install each nodes with RHEL 8

Register server and select minimal server option, standard server, development tools

Create user with root access

Login as user root

adduser openstack usermod -aG wheel openstack echo “openstack ALL=(ALL) NOPASSWD:ALL” | tee /etc/sudoers.d/openstack

Logout user root

Login as user openstack

Update RHEL

sudo dnf check-update sudo dnf update

Install required packages

sudo dnf install -y vim wget tcl systemd-devel.x86_64 python3

Modify /etc/sysctl.conf file

sudo vim /etc/sysctl.conf

Add following lines

vm.overcommit_memory=1 net.core.somaxconn=511

Configure firewall (need to check!)

sudo firewall-cmd –permanent –new-zone=redis sudo firewall-cmd –permanent –zone=redis –add-port=7000/tcp sudo firewall-cmd –permanent –zone=redis –add-port=7001/tcp sudo firewall-cmd –permanent –zone=redis –add-port=17000/tcp sudo firewall-cmd –permanent –zone=redis –add-port=17001/tcp sudo firewall-cmd –permanent –zone=redis –add-port=7000/tcp sudo firewall-cmd –permanent –zone=redis –add-source=10.6.10.0/24 sudo firewall-cmd –reload

Install redis server

wget https://download.redis.io/redis-stable.tar.gz tar xzf redis-stable.tar.gz cd redis-stable make make test sudo make install

Check installation

[root@node-1 ~]# whereis redis-server redis-server: /usr/local/bin/redis-server
[root@node-1 ~]# redis-server –version Redis server v=7.0.5 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=a49a56f97af1c0b0

Prepare required directories

On ALL nodessudo mkdir -p /etc/redis
On node-1sudo mkdir -p /var/redis/m1 sudo mkdir -p /var/redis/s3
On node-2sudo mkdir -p /var/redis/m2 sudo mkdir -p /var/redis/s1
On node-3sudo mkdir -p /var/redis/m3 sudo mkdir -p /var/redis/s2

Prepare configuration files

On node-3sudo cp ~/redis-stable/redis.conf /etc/redis/m3.conf sudo cp ~/redis-stable/redis.conf /etc/redis/s2.conf

Configure redis-server

node-1 / master-1

Edit /etc/redis/m1.conf

sudo vim /etc/redis/m1.conf

Change following lines

bind 127.0.0.1 10.6.10.21 protected-mode no port 7000 daemonize no supervised systemd pidfile /var/run/redis_m1.pid loglevel notice logfile “/var/log/redis_m1.log” save 900 1 300 10 60 10000 stop-writes-on-bgsave-error yes rdbchecksum yes dbfilename dump.rdb dir /var/redis/m1 replica-read-only yes maxmemory 64mb maxmemory-policy volatile-ttl appendonly yes cluster-enabled yes cluster-config-file nodes-m1.conf cluster-node-timeout 5000 cluster-replica-validity-factor 1 slowlog-log-slower-than 10000 slowlog-max-len 64 latency-monitor-threshold 100

Save and quit

Create systemd service file

sudo vim /etc/systemd/system/redis-m1.service

Add following lines

Reload service

sudo systemctl deamon-reload

Start redis-m1 service

sudo systemctl start redis-m1.service

Check status redis-m1 service

sudo systemctl status redis-m1.service
