Cara menggunakan port mysql 0

Untuk dapat mencoba melakukan replikasi master to master mysql ini, harap siapkan (minimal) 2 server mysql siap pakai, misalnya dengan IP 10. 2. 9. 1 dan 10. 2. 9. 2

MySQL Master untuk Menguasai Langkah Replikasi

1. Sesuaikan konfigurasi masing-masing server MySQL sebagai master. Ubah di setiap file /etc/my. cnf
Untuk master server 1 misalnya

[mysqld] port=3306 datadir=/home/mysql/ socket=/usr/local/mysql/tmp/mysql.sock user=mysql old_passwords=0 #symbolic-links=0 #query_cache_size = 268435456 query_cache_size = 256M query_cache_type=1 query_cache_limit = 1048576 log = 1 long_query_time = 1 slow_query_log = 1 slow_query_log_file = /var/log/mysql/mysql-slow.log general_log = 1 general_log_file = /var/log/mysqld.log server_id = 1 log_bin = /var/log/mysql/mysql-bin.log log_bin_index = /var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-relay-bin relay_log_index = /var/log/mysql/mysql-relay-bin.index expire_logs_days = 10 max_binlog_size = 100M log_slave_updates = 1 bind-address = 0.0.0.0 local-infile = 0

sedangkan untuk master server 2

[mysqld] port=3306 datadir=/home/mysql socket=/usr/local/mysql/tmp/mysql.sock user=mysql old_passwords=0 #symbolic-links=0 query_cache_size = 268435456 query_cache_type=1 query_cache_limit=1048576 log = 1 long_query_time = 1 slow_query_log = 1 slow_query_log_file = /var/log/mysql/mysql-slow.log general_log = 1 general_log_file = /var/log/mysqld.log server_id = 2 log_bin = /var/log/mysql/mysql-bin.log log_bin_index = /var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-relay-bin relay_log_index = /var/log/mysql/mysql-relay-bin.index expire_logs_days = 10 max_binlog_size = 100M log_slave_updates = 1 bind-address = 0.0.0.0 local-infile = 0 _

2. Instal replikasi ke setiap server, login ke server1 sebagai root
a. buat 3 pengguna untuk replikasi ini. mysqlchkuser, mmm_monitor, mmm_agent, dan replikasi
b. Berikan mmm_monitor sebagai replikasi klien
c. Berikan mmm_agent sebagai super dan replikasi klien
d. Berikan replikasi sebagai budak
e. hak siram mysql
f. flush juga baca lock mysql
g. periksa status master mysql
deskripsi langkah-langkah di atas dalam perintah dan respons di konsol sebagai berikut

mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

h. Dump database master server 1 ke master server 2 dengan mysqldump

mysqldump -u root -p --all-databases > /tmp/database-backup.sql

i. Transfer file backup ke master server 2 dengan scp,

scp /tmp/database-backup.sql 10.2.9.2:~/ _

j. Buka kunci tabel di master 1
3. Login ke master server 2 sebagai root di mysql
a. siram hak istimewa yang tersedia
b. ubah master mysql dengan master_host = '10. 2. 9. 1' (atau sesuai dengan IP server master Anda 1) diikuti oleh port (biasanya 3306), pengguna master (dalam hal ini 'replikasi'), kata sandi pengguna, dan file log mastering

mysql> flush privileges; Query OK, 0 rows affected (0.46 sec) mysql> CHANGE MASTER TO master_host='10.2.9.1', master_port=3306, master_user='replication', -> master_password='replication_password', master_log_file='mysql-bin.000001', master_log_pos=1044;

c. jalankan slave di server master 2 dan periksa status slave

mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status \G run command *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 10.2.9.1 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000001 Read_Master_Log_Pos: 1044 Relay_Log_File: mysql-relay-bin.000002 Relay_Log_Pos: 253 Relay_Master_Log_File: mysql-bin.000001 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 1044 Relay_Log_Space: 409 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 1 1 row in set (0.00 sec) _

d. memeriksa status master

mysql> show master status -> ; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000002 | 27957968 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec) mysql> show master status; +------------------+----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+----------+--------------+------------------+ | mysql-bin.000002 | 27957968 | | | +------------------+----------+--------------+------------------+ 1 row in set (0.00 sec)

4. Kembali ke server master 1 dan pengaturan master
a. Ganti mysql master dengan master host sesuai IP master server 2, sesuaikan port, user, password dan log file

mysql> CHANGE MASTER TO master_host='10.2.9.2', master_port=3306, master_user='replication', -> master_password='replication_password', master_log_file='mysql-bin.000002', master_log_pos=27957968; Query OK, 0 rows affected (0.34 sec) _

b. jalankan budak dan periksa statusnya

mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> show slave status\G run command *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 10.2.9.1 Master_User: replication Master_Port: 3306 Connect_Retry: 60 Master_Log_File: mysql-bin.000002 Read_Master_Log_Pos: 27957968 Relay_Log_File: mysql-relay-bin.000002 Relay_Log_Pos: 253 Relay_Master_Log_File: mysql-bin.000002 Slave_IO_Running: Yes Slave_SQL_Running: Yes Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 27957968 Relay_Log_Space: 409 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert: No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 2 1 row in set (0.00 sec) _

5. Percobaan replikasi
a. Di server master konsol 1, silakan lihat daftar basis data
b. Cobalah untuk membuat database baru

[mysqld] port=3306 datadir=/home/mysql socket=/usr/local/mysql/tmp/mysql.sock user=mysql old_passwords=0 #symbolic-links=0 query_cache_size = 268435456 query_cache_type=1 query_cache_limit=1048576 log = 1 long_query_time = 1 slow_query_log = 1 slow_query_log_file = /var/log/mysql/mysql-slow.log general_log = 1 general_log_file = /var/log/mysqld.log server_id = 2 log_bin = /var/log/mysql/mysql-bin.log log_bin_index = /var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-relay-bin relay_log_index = /var/log/mysql/mysql-relay-bin.index expire_logs_days = 10 max_binlog_size = 100M log_slave_updates = 1 bind-address = 0.0.0.0 local-infile = 0 _0

c. Coba periksa di master server 2, database sampel replikasi otomatis juga harus dibuat

[mysqld] port=3306 datadir=/home/mysql socket=/usr/local/mysql/tmp/mysql.sock user=mysql old_passwords=0 #symbolic-links=0 query_cache_size = 268435456 query_cache_type=1 query_cache_limit=1048576 log = 1 long_query_time = 1 slow_query_log = 1 slow_query_log_file = /var/log/mysql/mysql-slow.log general_log = 1 general_log_file = /var/log/mysqld.log server_id = 2 log_bin = /var/log/mysql/mysql-bin.log log_bin_index = /var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-relay-bin relay_log_index = /var/log/mysql/mysql-relay-bin.index expire_logs_days = 10 max_binlog_size = 100M log_slave_updates = 1 bind-address = 0.0.0.0 local-infile = 0 _1

Banyak. Selamat mencoba dan nikmati master MySQL untuk menguasai replikasi data
