Linux DNS Configuration

1. Install bind

# install bindyum install-y bind Bind-chroot bind-utils

2. master configuration file

Vi/etc/named.conf

# modify the listener to native IPlisten-on port 172.18.0.227;}; # allow all people to access allow-query     {any;};

3. Add a Domain Configuration

Vi/etc/named.rfc1912.zones

#Domain name configuration: Forward parsing configurationZone"wanmagroup.com" inch{type Master; File"Named.wanmagroup.com.zone"; allow-update {none;};};#Reverse parsing configurationZone"0.18.172.in-addr.arpa" inch{type Master; File"Named.0.18.172.in.zone"; allow-update {none;};};

Forward parsing configuration file establishment

# forward configuration parsing file $TTL 86400@ in             SOA     @       root. (                                        0       ; serial                                        1D      ; refresh                                        1H      ; retry                                        1W      ; expire                                        3H)    ; Minimum        in      NS      @ in              A       172.18.0.227*       in       A       172.18.0.227

# Reverse Configuration parsing file $TTL 1D@ in        SOA  @ root. (                                        0       ; serial                                        1D      ; refresh                                        1H      ; retry                                        1W      ; expire                                        3H)    ; Minimum        NS      @        A       172.18.0.227

4. Check the configuration

# Check the main profile named-checkconf# Check forward profile named-checkzone wanmagroup.com Named.wanmagroup.com.zone# Check the reverse configuration file named-checkzone wanmagroup.com named.0.18.172. in. Zone

5. Start the server

# Restart Service systemctl Restart Named.service # Check Service status systemctl status  named.service-l
