I check if the string equals the word stop to end the loop,but it say that I gave too many arguments to test.
For example echo hello.

Can you explain what this line of script is doing.
What I have understood is :

ocf_heartbeat_mysql
OCF_HEARTBEAT_MYSQL(7) OCF resource agents OCF_HEARTBEAT_MYSQL(7)NAME
ocf_heartbeat_mysql - Manages a MySQL database instance
SYNOPSIS
mysql [start | stop | status | monitor | promote | demote | notify | validate-all | meta-data]
DESCRIPTION
Resource script for MySQL. May manage a standalone MySQL database, a clone set with externally managed replication, or a complete
master/slave replication setup.
SUPPORTED PARAMETERS
binary
Location of the MySQL server binary (optional, string, default /usr/bin/mysqld_safe)
client_binary
Location of the MySQL client binary (optional, string, default mysql)
config
Configuration file (optional, string, default /etc/my.cnf)
datadir
Directory containing databases (optional, string, default /var/lib/mysql)
user
User running MySQL daemon (optional, string, default mysql)
group
Group running MySQL daemon (for logfile and directory permissions) (optional, string, default mysql)
log
The logfile to be used for mysqld. (optional, string, default /var/log/mysqld.log)
pid
The pidfile to be used for mysqld. (optional, string, default /var/lib/mysql/mysqld.pid)
socket
The socket to be used for mysqld. (optional, string, default /var/lib/mysql/mysql.sock)
test_table
Table to be tested in monitor statement (in database.table notation) (optional, string, default mysql.user)
test_user
MySQL test user (optional, string, default root)
test_passwd
MySQL test user password (optional, string, no default)
enable_creation
If the MySQL database does not exist, it will be created (optional, integer, default 0)
additional_parameters
Additional parameters which are passed to the mysqld on startup. (e.g. --skip-external-locking or --skip-grant-tables) (optional,
string, no default)
replication_user
MySQL replication user. This user is used for starting and stopping MySQL replication, for setting and resetting the master host, and
for setting and unsetting read-only mode. Because of that, this user must have SUPER, REPLICATION SLAVE, REPLICATION CLIENT, and
PROCESS privileges on all nodes within the cluster. (optional, string, no default)
replication_passwd
MySQL replication password. Used for replication client and slave. (optional, string, no default)
replication_port
The port on which the Master MySQL instance is listening. (optional, string, default 3306)
max_slave_lag
The maximum number of seconds a replication slave is allowed to lag behind its master. Do not set this to zero. What the cluster
manager does in case a slave exceeds this maximum lag is determined by the evict_outdated_slaves parameter. (optional, integer, default
3600)
evict_outdated_slaves
If set to true, any slave which is more than max_slave_lag seconds behind the master has its MySQL instance shut down. If this
parameter is set to false in a primitive or clone resource, it is simply ignored. If set to false in a master/slave resource, then
exceeding the maximum slave lag will merely push down the master preference so the lagging slave is never promoted to the new master.
(optional, boolean, default false)
SUPPORTED ACTIONS
This resource agent supports the following actions (operations):
start
Starts the resource. Suggested minimum timeout: 120.
stop
Stops the resource. Suggested minimum timeout: 120.
status
Performs a status check. Suggested minimum timeout: 60.

demote
Demotes the resource to the Slave role. Suggested minimum timeout: 120.
notify
Suggested minimum timeout: 90.
validate-all
Performs a validation of the resource configuration. Suggested minimum timeout: 5.
meta-data

primitive example_mysql ocf:heartbeat:mysql
op monitor depth="0" timeout="30" interval="10"
