In the three servers, built from three redis three main clusters

A resource ready

1, to prepare three servers H1, H2, H3

 

Second, the configuration server

1, a density log free SSH server in H1; RSA public and private keys generated in H1 (H1 operation)

(1) performs ssh-keygen -t rsa command
(2) to generate the key into the file directory where cd /root/.ssh/
(. 3) the public key (id_rsa.pub file name) is added to the certificate file (named authorized_keys files), has run the following command:

ssh-copy-id 172.26.237.83
ssh-copy-id 172.26.237.84
ssh-copy-id 172.26.237.85

 

(Note: IP here is H1, H2, H3 internal network IP, you need to enter server password yes and execution)

 

2, DNS configuration file ( responsible for mapping the host name to an IP address )

(1) env created in the root directory and enter the following command env directory

cat > /root/env/hosts.txt <<EOF
172.26.237.83 H1
172.26.237.84 H2
172.26.237.85 H3
EOF

cat /root/env/hosts.txt
cat /root/env/hosts.txt >> /etc/hosts
