环境： 虚拟机VMware， OS：CentOS Linux release 7.3.1611 (Core) 按照下述的单机Mysql8.0的安装方式进行安装完之后，将该机复制两台，分别修改IP为192.168.1.78和192.168.1.78，以及两台新机器配置文件/etc/my.cnf的serverid，还有要去数据路径下删掉auto.cnf不然配置不成。 vim /etc/hosts 192.168.1.78 mgr-mul1 192.168.1.79 mgr-mul2 192.168.1.80 mgr-mul3 要用hostname修改每台机器的主机名确保不相同，不然配置不成功。 一、单机安装(192.168.1.78) 官网下载8.0.11版本的tar.gz包解压，复制更名到/usr/local/mysql 创建数据路径及日志路径并把他们权限改给mysql用户： /data/mysql3306/mysql3306 /data/mysql3306/logs 配置文件如下：注意修改server-id及组相关ip vim /etc/my.cnf default_authentication_plugin = mysql_native_password skip_name_resolve = 1 character_set_server = utf8mb4 collation_server = utf8mb4_unicode_ci max_connections = 2000 max_connect_errors = 10000 interactive_timeout = 600 wait_timeout = 600 table_open_cache = 2048 thread_cache_size = 51 max_allowed_packet = 16M tmp_table_size = 256M max_heap_table_size = 96M sort_buffer_size = 4M read_buffer_size = 4M #??IO join_buffer_size = 4M read_rnd_buffer_size = 64M #??篓虏 bulk_insert_buffer_size = 64M # log_error = /data/mysql3306/logs/mysql-error.log log_timestamps = system slow_query_log = 1 slow_query_log_file = /data/mysql3306/logs/mysql-slow.log long_query_time = 1 log_queries_not_using_indexes = 1 log_throttle_queries_not_using_indexes =10 log_slow_admin_statements = 1 log_slow_slave_statements = 1 min_examined_row_limit = 100 log_queries_not_using_indexes = 1 log_output = FILE relay_log = /data/mysql3306/mysql3306/mysql-relay #binlog server_id = 1783306 log_bin = /data/mysql3306/mysql3306/mysql-bin binlog_expire_logs_seconds =604800 binlog_format = row max_binlog_size = 1024M max_binlog_cache_size = 8G binlog_cache_size = 4M sync_binlog = 1 master_info_repository = TABLE relay_log_info_repository = TABLE relay_log_recovery = ON log_slave_updates = 1 slave-parallel-type=LOGICAL_CLOCK slave-parallel-workers=16 master_info_repository=TABLE relay_log_info_repository=TABLE relay_log_recovery=ON binlog_checksum=NONE slave_preserve_commit_order=1 #group_replication_flow_control_mode=DISABLED log_slave_updates=1 #GR enforce_gtid_consistency=1 gtid_mode = on transaction_write_set_extraction =XXHASH64 # off loose-group_replication_group_name ="a876d35e-9110-11e6-a365-882b2b5s09d6" #可在库里使用SELECT UUID()生成，一个组的所有机器都相同。 loose-group_replication_local_address ="192.168.1.78:24900" #本机IP loose-group_replication_group_seeds ="192.168.1.78:24900,192.168.1.79:24900,192.168.1.80:24900" loose-group_replication_bootstrap_group =off # off loose-group_replication_start_on_boot =off #非常重要。 （编辑：核心网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
