59 | # |
---|
60 | # To configure this host as a replication slave, you can choose between |
---|
61 | # two methods : |
---|
62 | # |
---|
63 | # 1) Use the CHANGE MASTER TO command (fully described in our manual) - |
---|
64 | # the syntax is: |
---|
65 | # |
---|
66 | # CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, |
---|
67 | # MASTER_USER=<user>, MASTER_PASSWORD=<password> ; |
---|
68 | # |
---|
69 | # where you replace <host>, <user>, <password> by quoted strings and |
---|
70 | # <port> by the master's port number (3306 by default). |
---|
71 | # |
---|
72 | # Example: |
---|
73 | # |
---|
74 | # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, |
---|
75 | # MASTER_USER='joe', MASTER_PASSWORD='secret'; |
---|
76 | # |
---|
77 | # OR |
---|
78 | # |
---|
79 | # 2) Set the variables below. However, in case you choose this method, then |
---|
80 | # start replication for the first time (even unsuccessfully, for example |
---|
81 | # if you mistyped the password in master-password and the slave fails to |
---|
82 | # connect), the slave will create a master.info file, and any later |
---|
83 | # change in this file to the variables' values below will be ignored and |
---|
84 | # overridden by the content of the master.info file, unless you shutdown |
---|
85 | # the slave server, delete master.info and restart the slaver server. |
---|
86 | # For that reason, you may want to leave the lines below untouched |
---|
87 | # (commented) and instead use CHANGE MASTER TO (see above) |
---|
88 | # |
---|
89 | # required unique id between 2 and 2^32 - 1 |
---|
90 | # (and different from the master) |
---|
91 | # defaults to 2 if master-host is set |
---|
92 | # but will not function as a slave if omitted |
---|
93 | #server-id = 2 |
---|
94 | # |
---|
95 | # The replication master for this slave - required |
---|
96 | #master-host = <hostname> |
---|
97 | # |
---|
98 | # The username the slave will use for authentication when connecting |
---|
99 | # to the master - required |
---|
100 | #master-user = <username> |
---|
101 | # |
---|
102 | # The password the slave will authenticate with when connecting to |
---|
103 | # the master - required |
---|
104 | #master-password = <password> |
