  • Start HAProxy:
    systemctl restart haproxy

Note

If when restarting HAProxy this error is thrown “Starting frontend www-https-svc: cannot bind socket [0.0.0.0:91]”, either disable SELinux or run this command:

setsebool -P haproxy_connect_any=1

Create a Self-Signed SSL Certificate

A new more modern approach is to make an openssl.conf file first, here is an example:

Code Block
[ req ]
prompt = no
distinguished_name = server_distinguished_name
req_extensions = v3_req
default_md = sha256

[ server_distinguished_name ]
commonName = *.swarm.example.com
stateOrProvinceName = Texas
countryName = US
emailAddress = admin@example.com
organizationName = Example Inc.
localityName = Austin

[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = critical, digitalSignature, keyEncipherment
extendedKeyUsage=critical,serverAuth,clientAuth
subjectAltName = @alt_names

[ alt_names ]
DNS.1=swarm.example.com
DNS.2=*.swarm.example.com

Generate the self-signed CA private key

Code Block
openssl genrsa  -out selfsignCA.key 4096

Generate the self-signed CA root certificate

Code Block
openssl req -new -x509 -days 365 -key selfsignCA.key -out selfsignCA.crt -batch

Generate wildcard custom domain certificate

Code Block
openssl genrsa -out YOUR_DOMAIN.key 4096

Generate certificate signing request for your domain

Code Block
openssl req -new -nodes -key YOUR_DOMAIN.key -config openssl.conf -out YOUR_DOMAIN.csr

Generate the final domain certificate

Code Block
openssl x509 -req -in YOUR_DOMAIN.csr -CA selfsignCA.crt -CAkey selfsignCA.key -CAcreateserial -out YOUR_DOMAIN.crt -days 365 -sha256 -extfile openssl.conf -extensions v3_req

Generate the certificate pem file.

Code Block
cat YOUR_DOMAIN.crt YOUR_DOMAIN.key > YOUR_DOMAIN.pem

Place the pem file where you configured it in haproxy.cfg example here put it in /etc/pki/tls/certs

Code Block
bind 0.0.0.0:443 ssl crt /etc/pki/tls/certs/YOUR_DOMAIN.pem

The host <contentgatewayIP>:8091 needs to be used in the login page to connect for Swarm UI in the configuration example above.

Info

Copy your selfsignCA.crt file to /etc/pki/ca-trust/source/anchors and run update-ca-trust to test the new certificate from a CentOS 7.x client. curl may then used to test the certificate validation once the command completes.

Replication Feed configuration

The following setting must appear and be set properly in the /etc/caringo/cloudgateway/gateway.cfg file if the content gateway is going to be used as the destination for a remote replication feed:

Code Block
[scsp]
...
allowSwarmAdminIP=172.30

In the example above, replicate "172.30" with the IP addresses (or prefix) of clients sending administrative requests to the gateway.

  • Start HAProxy:
    systemctl restart haproxy

Note

If when restarting HAProxy this error is thrown “Starting frontend www-https-svc: cannot bind socket [0.0.0.0:91]”, either disable SELinux or run this command:

setsebool -P haproxy_connect_any=1

Loadbalancing healthcheck

If you have 2 or more gateways, it is recommended to use the http-check directives to verify the service is live.

Each protocol requires different healthcheck configuration.

SCSP Protocol

HAPROXY < 2.2

Code Block
    option httpchk HEAD /_admin/manage/version HTTP/1.1\r\nHost:\ haproxy-healthcheck
    http-check expect status 200

HAPROXY > 2.2

Code Block
    option httpchk
    http-check connect
    http-check send meth HEAD uri /_admin/manage/version ver HTTP/1.1 hdr Host haproxy-healthcheck
    http-check expect status 200

S3 Protocol

HAPROXY < 2.2

Code Block
    option httpchk HEAD / HTTP/1.1\r\nHost:\ haproxy-healthcheck
    http-check expect status 403

HAPROXY > 2.2

Code Block
    option httpchk
    http-check connect
    http-check send meth HEAD uri / ver HTTP/1.1 hdr Host haproxy-healthcheck
    http-check expect status 403

Admin Protocol ( cluster_admin )

HAPROXY < 2.2

Code Block
    option httpchk HEAD / HTTP/1.1\r\nHost:\ haproxy-healthcheck
    http-check expect status 401

HAPROXY > 2.2

Code Block
    option httpchk
    http-check connect
    http-check send meth HEAD uri / ver HTTP/1.1 hdr Host haproxy-healthcheck
    http-check expect status 401

Backend section for all protocols

Code Block
server gw1 YOUR_GATEWAY1_IP:8090 check inter 10s fall 3 rise 2
server gw2 YOUR_GATEWAY2_IP:8090 check inter 10s fall 3 rise 2

Example Logging with SCSP health check

In the following example I ran a while loop, to read an object every second… and while doing it shutdown 1 of the 2 gateways waited a few seconds then started it back up.

Create a Self-Signed SSL Certificate

First we need to make an openssl.conf file, in this example YOUR_DOMAIN = swarm.example.com

Code Block
[ req ]
prompt = no
distinguished_name = server_distinguished_name
req_extensions = v3_req
default_md = sha256

[ server_distinguished_name ]
commonName = *.swarm.example.com
stateOrProvinceName = Texas
countryName = US
emailAddress = admin@example.com
organizationName = Example Inc.
localityName = Austin

[ v3_req ]
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names

[ alt_names ]
DNS.1=swarm.example.com
DNS.2=*.swarm.example.com

Generate the self-signed CA private key

Code Block
openssl genrsa  -out selfsignCA.key 4096

Generate the self-signed CA root certificate

Code Block
openssl req -new -x509 -nodes -days 365 -sha256 -key selfsignCA.key -out selfsignCA.crt -subj "/C=US/O=_DEV CA/CN=SelfSigned certificates"

Generate wildcard custom domain private key

Code Block
openssl genrsa -out YOUR_DOMAIN.key 4096

Generate certificate signing request for your domain

Code Block
openssl req -new -nodes -key YOUR_DOMAIN.key -config openssl.conf -out YOUR_DOMAIN.csr

Generate the final domain certificate

Code Block
openssl x509 -req -in YOUR_DOMAIN.csr -CA selfsignCA.crt -CAkey selfsignCA.key -CAcreateserial -out YOUR_DOMAIN.crt -days 365 -sha256 -extfile openssl.conf -extensions v3_req

Generate the certificate pem file.

Code Block
cat YOUR_DOMAIN.crt YOUR_DOMAIN.key > YOUR_DOMAIN.pem

Place the YOUR_DOMAIN.pem file where you configured it in haproxy.cfg example here put it in /etc/pki/tls/certs

Code Block
bind 0.0.0.0:443 ssl crt /etc/pki/tls/certs/YOUR_DOMAIN.pem

Copy the selfsignCA.crt to /etc/pki/ca-trust/source/anchors and run update-ca-trust to tell CentOS to trust your self-signed root certificate.

Note

This is an important step for haproxy as by default it is configured to look for trusted certificates in the /etc/pki/tls/certs folder. ( see ca-base parameter )

Restart haproxy to activate the changes.

Now you can copy the selfsignCA.crt file to your clients and follow the browser specific procedures to install and accept it.

The host <contentgatewayIP>:8091 needs to be used in the login page to connect for Swarm UI in the configuration example above.

Replication Feed configuration

The following setting must appear and be set properly in the /etc/caringo/cloudgateway/gateway.cfg file if the content gateway is going to be used as the destination for a remote replication feed:

Code Block
[scsp]
...
allowSwarmAdminIP=172.30

In the example above, replicate "172.30" with the IP addresses (or prefix) of clients sending administrative requests to the gateway.

The most common example is the IP addresses (or prefix) of the nodes in a cluster using a remote replication feed with the gateway as the destination.

Troubleshooting tips

If you occasionally see the error SEC_ERROR_UNKNOWN_ISSUER , verify you don't have lingering old haproxy processes , and kill them manually.

To check if your selfsigned CA certificate is trusted run the following command:

Code Block
trust list --filter=ca-anchors | grep Self -i -A2 -B4

Example Output you should see:
pkcs11:id=%f4%a2%f6%c6%e4%db%bc%c8%a1%23%83%d3%67%14%7c%51%c1%8d%bd%ba;type=cert
    type: certificate
    label: SelfSigned certificates
    trust: anchor
    category: authority

for CentOS7 and haproxy 1.8 by default require additional log settings to see the output in a file, add the following line in /etc/rsyslog.conf after the boot.log

Code Block
local2.*    /var/log/haproxy.log

then run

Code Block
systemctl restart rsyslog

you should now see haproxy logging in /var/log/haproxy.log

Do not forget to enable the ports on your firewall

Code Block
firewall-cmd --add-port=443/tcp --permanent
firewall-cmd --add-port=80/tcp --permanent
firewall-cmd --reload
Info

Keep in mind that normally you have multiple zone’s , since gateway has 2 adapters, the above example only adds the ports to the Default firewall zone
