MariaDB Galera क्लस्टर कॉन्फ़िगर करें।
इस मल्टी-मास्टर कॉन्फ़िगरेशन पर क्लस्टर के सभी नोड मास्टर-सर्वर बन जाते हैं। |
|
| [1] | |
| [2] | पहले नोड को निम्नानुसार कॉन्फ़िगर करें। |
|
root@www:~# systemctl stop mariadb
root@www:~#
vi /etc/mysql/mariadb.conf.d/50-server.cnf # पंक्ति 27: टिप्पणी करें # bind-address = 127.0.0.1
# अंत में जोड़ें [galera] wsrep_on=ON wsrep_provider=/usr/lib/galera/libgalera_smm.so wsrep_cluster_address="gcomm://" binlog_format=row default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 bind-address=0.0.0.0 # किसी भी क्लस्टर का नाम wsrep_cluster_name="MariaDB_Cluster" # स्वयं का आईपी पता wsrep_node_address="10.0.0.31"
root@www:~#
galera_new_cluster
root@www:~#
vi /etc/mysql/mariadb.conf.d/50-server.cnf # वे नोड जोड़ें जिन्हें आप क्लस्टर में सेट करने की योजना बना रहे हैं wsrep_cluster_address="gcomm:// 10.0.0.31,10.0.0.51 "
|
| [3] | पहले नोड को छोड़कर अन्य नोड्स को कॉन्फ़िगर करें। |
|
root@node01:~#
vi /etc/mysql/mariadb.conf.d/50-server.cnf # पंक्ति 27: टिप्पणी करें # bind-address = 127.0.0.1
# अंत में जोड़ें [galera] wsrep_on=ON wsrep_provider=/usr/lib/galera/libgalera_smm.so # क्लस्टर में सभी नोड्स निर्दिष्ट करें wsrep_cluster_address="gcomm://10.0.0.31,10.0.0.51" binlog_format=row default_storage_engine=InnoDB innodb_autoinc_lock_mode=2 bind-address=0.0.0.0 # किसी भी क्लस्टर का नाम wsrep_cluster_name="MariaDB_Cluster" # इस होस्ट का IP पता निर्दिष्ट करें wsrep_node_address="10.0.0.51" systemctl restart mariadb |
| [4] | ठीक है। सुनिश्चित करें कि स्थिति इस प्रकार है। यह ठीक है अगर [wsrep_local_state_comment] [Synced] है। |

root@node01:~# mysql
