+## Ansible playbook for deploying mysql-server 5.7 galera cluster with HAproxy as load balancer
+### Features of Mysql 5.7 Galera Cluster
+* True Multi-master,  Active-Active Cluster Read and write to any node at any time.
+* Synchronous Replication No slave lag, no data is lost at node crash.
+* Tightly Coupled All nodes hold the same state. No diverged data between nodes allowed.
+* Multi-threaded Slave For better performance. For any workload.
+* No Master-Slave Failover Operations or Use of VIP.
+* Hot Standby No downtime during failover (since there is no failover).
+* Automatic Node Provisioning No need to manually back up the database and copy it to the new node.
+* Supports InnoDB.
+* Transparent to Applications Required no (or minimal changes) to the application.
+* No Read and Write Splitting Needed.
+* Easy to Use and Deploy
+
+### Requirements
+
+This playbook requires minimum of 3 ubuntu 16.04 nodes (you can add more nodes as needed) for installing mysql 5.7 galera cluster and 1 ubuntu 16.04 node for installing HAproxy. cluster nodes and proxy node must be defined inside the included inventory.yml file.

+
+### Running Playbook
+
+add hosts to `inventory.yml`
+
+Note: Do not modify the host group names [mysql_cluster] and [load_balancer] when adding hosts to `inventory.yml` file since it has dependencies inside the playbook. 
+
+```
+[mysql_cluster]
+mysql_node_1 ansible_host=192.168.10.2 ansible_port=22 ansible_user=ubuntu
+mysql_node_2 ansible_host=192.168.10.3 ansible_port=22 ansible_user=ubuntu
+mysql_node_3 ansible_host=192.168.10.4 ansible_port=22 ansible_user=ubuntu
+[load_balancer]
+haproxy_load_balancer ansible_host=192.168.10.5 ansible_port=22 ansible_user=ubuntu
+```
+Before running the playbook you have to configure below variables inside the playbook : `deploy-mysql-cluster.yml`
+
+`mysql_cluster_name: demo_mysql_cluster`  <= name of your mysql cluster without spaces 
+
+`mysql_root_password: your_mysql_root_password` <= a strong password for mysql root user
+
+#### To run the playbook 
+
+`ansible-playbook --fork=1 deploy-mysql-cluster.yml -i inventory.yml`
+
+##### Note: The ansible option `--fork=1` is used to disable parallel execution of tasks, which helps in data consistency when stopping/bootstrapping the cluster. 
+
+After successful completion of playbook, you can access the cluster by `mysql -h load_balancer_IP -P 3306 -u root -p your_mysql_root_password`
+
+### Verifying cluster status
+
+check the last part of playbook output 
+
+```
+ok: [haproxy_load_balancer] => {
+    "msg": [
+        " Test connection successfull", 
+        " Total number of active mysql nodes in cluster: '3 '", 
+        " Setup Completed!"
+    ]
+}
+
+
+```
+
+You can also verfiy the status of mysql cluster by manually running below query   
+~~~~sql
+`mysql -h load_balancer_IP -P 3306 -u root -p your_mysql_root_password`
+
+`mysql> SHOW STATUS LIKE 'wsrep_cluster_size';
++--------------------+-------+
+| Variable_name      | Value |
++--------------------+-------+
+| wsrep_cluster_size | 3     |
++--------------------+-------+
+1 row in set (0.00 sec)`
+
+~~~~
+Which means we have 3 active nodes 
+ 
+
+### Stop Mysql Cluster
+
+You can use the --tag option "stop_cluster" to safely stop the mysql cluster
+
+`ansible-playbook --fork=1 deploy-mysql-cluster.yml -i inventory.yml --tags "stop_cluster"`
+
+### Start Mysql Clsuter
+
+
+You can use the --tag option "start_cluster" to safely start/bootstrap the mysql cluster
+
+`ansible-playbook --fork=1 deploy-mysql-cluster.yml -i inventory.yml --tags "start_cluster"`
