12.4. PoolとVirtual Serverの設定

12.4.1. HTTP (80)用PoolとVS

• Pool設定と確認

(tmos)# create ltm pool http-pool-01 { members add { 10.1.20.201:http { } 10.1.20.202:http { } } monitor http }
(tmos)# list ltm pool
ltm pool http-pool-01 {
    members {
        10.1.20.201:http {
            address 10.1.20.201
            session monitor-enabled
            state up
        }
        10.1.20.202:http {
            address 10.1.20.202
            session monitor-enabled
            state up
        }
    }
    monitor http
}

• VS設定

(tmos)# create ltm virtual http-vs-001 { destination 10.1.10.60:http pool http-pool-01 profiles add { http } source-address-translation { type automap } }
(tmos)# list ltm virtual
ltm virtual http-vs-001 {
    creation-time 2019-07-01:18:07:15
    destination 10.1.10.60:http
    ip-protocol tcp
    last-modified-time 2019-07-01:18:07:15
    mask 255.255.255.255
    pool http-pool-01
    profiles {
        http { }
        tcp { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    vs-index 23
}

• パーシステンス設定

(tmos)# modify ltm virtual http-vs-001 { persist replace-all-with { source_addr }}
(tmos)# list ltm virtual
ltm virtual http-vs-001 {
    creation-time 2019-07-01:18:07:15
    destination 10.1.10.60:http
    ip-protocol tcp
    last-modified-time 2019-07-01:18:07:15
    mask 255.255.255.255
    persist {
        source_addr {
            default yes
        }
    }
    pool http-pool-01
    profiles {
        http { }
        tcp { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    vs-index 23
}

12.4.2. HTTP (80)用PoolとVS

後のshowコマンドで、コネクションテーブルの確認が行いやすいので、SSH用VSも作っておきます。

• Pool設定

(tmos)# create ltm pool ssh-pool-001 { members add { 10.1.20.201:ssh { } 10.1.20.202:ssh { } } monitor tcp }
(tmos)# list ltm pool ssh-pool-001
ltm pool ssh-pool-001 {
    members {
        10.1.20.201:ssh {
            address 10.1.20.201
            session monitor-enabled
            state up
        }
        10.1.20.202:ssh {
        address 10.1.20.202
            session monitor-enabled
            state up
        }
    }
    monitor tcp
}

• VS設定

(tmos)# create ltm virtual ssh-vs-001 { destination 10.1.20.60:ssh pool ssh-pool-001 profiles replace-all-with { tcp } source-address-translation { type automap } }
(tmos)# list ltm virtual ssh-vs-001
ltm virtual ssh-vs-001 {
    creation-time 2019-07-01:18:18:09
    destination 10.1.20.60:ssh
    ip-protocol tcp
    last-modified-time 2019-07-01:18:18:09
    mask 255.255.255.255
    pool ssh-pool-001
    profiles {
        tcp { }
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    translate-address enabled
    translate-port enabled
    vs-index 24
}
