# Replication Slave (comment out master section to use this) |
| 70 |
# |
| 71 |
# To configure this host as a replication slave, you can choose between |
| 72 |
# two methods : |
| 73 |
# |
| 74 |
# 1) Use the CHANGE MASTER TO command (fully described in our manual) - |
| 75 |
# the syntax is: |
| 76 |
# |
| 77 |
# CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, |
| 78 |
# MASTER_USER=<user>, MASTER_PASSWORD=<password> ; |
| 79 |
# |
| 80 |
# where you replace <host>, <user>, <password> by quoted strings and |
| 81 |
# <port> by the master's port number (3306 by default). |
| 82 |
# |
| 83 |
# Example: |
| 84 |
# |
| 85 |
# CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, |
| 86 |
# MASTER_USER='joe', MASTER_PASSWORD='secret'; |
| 87 |
# |
| 88 |
# OR |
| 89 |
# |
| 90 |
# 2) Set the variables below. However, in case you choose this method, then |
| 91 |
# start replication for the first time (even unsuccessfully, for example |
| 92 |
# if you mistyped the password in master-password and the slave fails to |
| 93 |
# connect), the slave will create a master.info file, and any later |
| 94 |
# change in this file to the variables' values below will be ignored and |
| 95 |
# overridden by the content of the master.info file, unless you shutdown |
| 96 |
# the slave server, delete master.info and restart the slaver server. |
| 97 |
# For that reason, you may want to leave the lines below untouched |
| 98 |
# (commented) and instead use CHANGE MASTER TO (see above) |
| 99 |
# |
| 100 |
# required unique id between 2 and 2^32 - 1 |
| 101 |
# (and different from the master) |
| 102 |
# defaults to 2 if master-host is set |
| 103 |
# but will not function as a slave if omitted |
| 104 |
#server-id = 2 |
| 105 |
# |
| 106 |
# The replication master for this slave - required |
| 107 |
#master-host = <hostname> |
| 108 |
# |
| 109 |
# The username the slave will use for authentication when connecting |
| 110 |
# to the master - required |
| 111 |
#master-user = <username> |
| 112 |
# |
| 113 |
# The password the slave will authenticate with when connecting to |
| 114 |
# the master - required |
| 115 |
#master-password = <password> |
| 116 |

# The port the master is listening on. |

# optional - defaults to 3306 |
