Setup Cluster - 2 SCs

1. Introduction.

2. Build Docker Image.

Create a Dockerfile with the following content.

  
FROM ubuntu:16.04

RUN apt update
RUN apt install -y \
    sudo sqlite3 libxml2 psmisc \
    python2.7-minimal net-tools kmod
RUN apt install -y \
    mercurial gcc g++ libxml2-dev automake \
    m4 autoconf libtool pkg-config \
    make python-dev libsqlite3-dev binutils
RUN apt install -y \
    vim iputils-ping rsyslog

RUN cd /root && hg clone http://hg.code.sf.net/p/opensaf/staging opensaf-staging

WORKDIR /root/opensaf-staging
RUN ./bootstrap.sh
RUN ./configure --enable-tipc CPPFLAGS="-DRUNASROOT"
RUN make -j `nproc`
RUN make install
RUN ldconfig

Build docker image.

  
$ docker build --progress=plain -t opensaf .

3. Setup SC-1.

3.1. Launch Docker Container.

  
$ docker run --privileged -it --name node1 -h SC-1 opensaf

3.2. Configure.

Generate /etc/opensaf/imm.xml.

  
$ cd /usr/local/share/opensaf/immxml/

# generate nodes.cfg
$ ./immxml-clustersize --sc-count 2
Successful, result stored in the file ./nodes.cfg

$ ./immxml-configure
Successfully generated the imm file: ./imm.xml.20241015_1721

$ cp ./imm.xml.20241015_1721 /etc/opensaf/imm.xml

Edit /etc/opensaf/node_name.

  
SC-1
# SC-1: hostname.

Edit /etc/opensaf/nid.conf.

  
# MDS transport protocol, values supported are TIPC or TCP
export MDS_TRANSPORT=TCP

Edit /etc/opensaf/dtmd.conf.

  
DTM_NODE_IP=172.17.0.2
# 172.17.0.2: IP of the eth0 interface.

Edit /etc/opensaf/slot_id.

  
1

Edit /etc/opensaf/node_type.

  
controller

3.3. Start OpenSAF.

Start OpenSAF.

   
$ /etc/init.d/opensafd start
Starting OpenSAF Services (Using TCP): *

Check status.

  
$ /etc/init.d/opensafd status
safSISU=safSu=SC-1\,safSg=NoRed\,safApp=OpenSAF,safSi=NoRed1,safApp=OpenSAF
        saAmfSISUHAState=ACTIVE(1)
safSISU=safSu=SC-1\,safSg=2N\,safApp=OpenSAF,safSi=SC-2N,safApp=OpenSAF
        saAmfSISUHAState=ACTIVE(1)

4. Setup SC-2.

4.1. Launch Docker Container.

  
$ docker run --privileged -it --name node2 -h SC-2 opensaf

4.2. Configure.

Edit /etc/opensaf/node_name.

  
SC-2
# SC-2: hostname.

Edit /etc/opensaf/nid.conf.

  
# MDS transport protocol, values supported are TIPC or TCP
export MDS_TRANSPORT=TCP

Edit /etc/opensaf/dtmd.conf.

  
DTM_NODE_IP=172.17.0.3
# 172.17.0.3: IP of the eth0 interface.

Edit /etc/opensaf/slot_id.

  
2

Edit /etc/opensaf/node_type.

  
controller

4.3. Start OpenSAF.

Start rsyslog because opensaf print logs to rsyslog.

  
$ /etc/init.d/rsyslog start

Start opensaf.

   
$ /etc/init.d/opensafd start
Starting OpenSAF Services (Using TCP): *

Check status.

  
$ /etc/init.d/opensafd status
safSISU=safSu=SC-1\,safSg=2N\,safApp=OpenSAF,safSi=SC-2N,safApp=OpenSAF
        saAmfSISUHAState=ACTIVE(1)
safSISU=safSu=SC-1\,safSg=NoRed\,safApp=OpenSAF,safSi=NoRed1,safApp=OpenSAF
        saAmfSISUHAState=ACTIVE(1)
safSISU=safSu=SC-2\,safSg=NoRed\,safApp=OpenSAF,safSi=NoRed2,safApp=OpenSAF
        saAmfSISUHAState=ACTIVE(1)
safSISU=safSu=SC-2\,safSg=2N\,safApp=OpenSAF,safSi=SC-2N,safApp=OpenSAF
        saAmfSISUHAState=STANDBY(2)

5. Test.

Check state of nodes.

  
$ amf-state node
safAmfNode=SC-1,safAmfCluster=myAmfCluster
        saAmfNodeAdminState=UNLOCKED(1)
        saAmfNodeOperState=ENABLED(1)
safAmfNode=SC-2,safAmfCluster=myAmfCluster
        saAmfNodeAdminState=UNLOCKED(1)
        saAmfNodeOperState=ENABLED(1)

Check /var/log/syslog on SC-1.

  
SC-1 osafdtmd[133]: NO Established contact with 'SC-2'
SC-1 osafamfd[224]: NO Node 'SC-2' joined the cluster

Check /var/log/syslog on SC-2.

  
SC-2 osafdtmd[70]: NO Established contact with 'SC-1'
SC-2 osafclmna[83]: NO safNode=SC-2,safCluster=myClmCluster Joined cluster, nodeid=2020f
SC-2 osafamfd[154]: NO Cold sync complete!
