yum install -y corosync pacemaker pcs
systemctl start pcsd && systemctl enable pcsd && systemctl status pcsd
echo "PCSD_PORT=18888" >> /etc/sysconfig/pcsd
systemctl restart pcsd
echo '123456' | passwd --stdin hacluster

手工創建刪除haproxy容器
# docker run -itd --net=host --dns 8.8.8.8 \
--name=haproxy1 -h haproxy1 \
-v /etc/localtime:/etc/localtime:ro \
-v /root/linz/haproxy.cfg:/etc/haproxy/haproxy.cfg:ro \
--privileged \
haproxy-init:v1.0 \
/usr/sbin/haproxy -f /etc/haproxy/haproxy.cfg -Ds
刪除容器
# docker rm -f haproxy1
ocf:heartbeat:docker允許使用的設置
# pcs resource describe ocf:heartbeat:docker
可設置選項: allow_pull, force_kill, image, monitor_cmd, mount_points, name, query_docker_health, reuse, run_cmd, run_opts, trace_file, trace_ra
# cat /usr/lib/ocf/resource.d/heartbeat/docker
ocf_run docker run $run_opts $OCF_RESKEY_image $OCF_RESKEY_run_cmd
$run_opts默認設置有-d --name=${CONTAINER}
