这篇文章将为大家详细讲解有关MySQL多实例的安装方法是什么，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。 Step 1 . 准备工作 关闭防火墙; 安装 MySQL依赖于libaio 库；下载，解压，重命名 MySQL的执行文件；新建用户组和用户 等准备工作在此不再赘述。 可执行文件目录为 /data/mysql57 添加用户和组的指令 groupadd mysql useradd mysql -g mysql Step 2 . 添加环境变量 在/etc/profile文件中，追加 PATH=${PATH}:/data/mysql57/bin/ 保存后，如需要立即生效，可执行 source /etc/profile 。 step 3 . 创建目录并授权 在data根目录下执行 mkdir -p mysql3306/data mysql3306/mysql_log mysql3306/tmp mysql3307/data mysql3307/mysql_log mysql3307/tmp mysqld_multi/log MySQL多实例的安装方法是什么 创建记录log的文件，此步骤不可少。 touch /data/mysql3306/mysql_log/mysql3306.errtouch /data/mysql3307/mysql_log/mysql3307.err 赋予目录和文件权限 chown -R mysql.mysql mysql3* mysqld_multi 在本测试案例中，mysql57是从其它服务上copy来的，不是直接下载解压的，所以多了下面的两步授权操作。 chmod -R 755 /data/mysql57/bin chmod -R 755 /data/mysql57/support-files step 4 . 编辑my.cnf [client] host=localhost socket = /tmp/mysql.sock default-character-set=utf8mb4 #loose-local-infile=0 [mysqld] user=mysql log_bin_trust_function_creators=1 secure_file_priv='/tmp' ########server setting####### sql_mode = "ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" character-set-server=utf8mb4 collation_server=utf8mb4_unicode_ci lower_case_table_names = 0 skip_name_resolve = 1 #max_connect_errors = 1000 max_connections = 2000 thread_cache_size=256 #thread_stack= 262144 #back_log=80 max_allowed_packet = 134217728 event_scheduler = 1 local-infile=0 #lower_case_table_names = 1 explicit_defaults_for_timestamp = 1 expire_logs_days = 7 log_bin_trust_function_creators =1 ####.frm/.ibd files qty related open_files_limit=65535 innodb_open_files=65535 table_open_cache=65535 table_definition_cache=65535 #### seesion buffer related read_buffer_size = 262144 read_rnd_buffer_size = 524288 sort_buffer_size = 8388608 join_buffer_size = 8388608 ####memory table size tmp_table_size =67108864 max_heap_table_size=67108864 ####timeout interactive_timeout = 1800 wait_timeout = 1800 # connect_timeout=10 ########slow query ######## slow_query_log = 1 log_slow_slave_statements = 1 #log_queries_not_using_indexes = 1 log_throttle_queries_not_using_indexes = 10 long_query_time = 1 #min_examined_row_limit = 10000 ########innodb settings######## innodb_buffer_pool_size = 10737418240 innodb_buffer_pool_instances = 16 innodb_buffer_pool_dump_pct = 40 innodb_lru_scan_depth = 2048 innodb_page_cleaners = 16 #innodb_purge_threads = 4 innodb_sort_buffer_size = 67108864 #innodb_file_per_table = 1 #innodb_flush_log_at_trx_commit = 1 innodb_undo_log_truncate = 1 innodb_undo_tablespaces = 3 innodb_max_undo_log_size = 2147483648 innodb_purge_rseg_truncate_frequency = 128 innodb_log_file_size = 1073741824 innodb_log_files_in_group = 3 innodb_log_buffer_size = 16777216 innodb_flush_method = O_DIRECT innodb_flush_neighbors = 0 innodb_print_all_deadlocks = 1 innodb_strict_mode = 1 #innodb_lock_wait_timeout = 50 innodb_io_capacity = 32768 innodb_io_capacity_max = 65536 innodb_thread_concurrency = 32 innodb_write_io_threads = 8 innodb_read_io_threads = 8 ########replication settings######## master_info_repository = TABLE relay_log_info_repository = TABLE gtid_mode = on enforce_gtid_consistency = 1 binlog_gtid_simple_recovery=1 relay_log_recovery = 1 slave-parallel-type = LOGICAL_CLOCK slave-parallel-workers = 16 slave_transaction_retries=128 slave_preserve_commit_order=1 log_slave_updates=1 binlog_format = ROW log_timestamps=system binlog_rows_query_log_events = 1 binlog_row_image='full' slave_skip_errors = ddl_exist_errors ########semi sync replication settings######## ##plugin_dir=/data/mysql/plugin/ #plugin_load = "rpl_semi_sync_master=semisync_master.so;rpl_semi_sync_slave=semisync_slave.so" #rpl_semi_sync_master_enabled = 1 #rpl_semi_sync_master_timeout = 5000 #rpl_semi_sync_slave_enabled = 1 [mysqld_multi] mysqld = /data/mysql57/bin/mysqld_safe mysqladmin = /data/mysql57/bin/mysqladmin log = /data/mysqld_multi/log/mysqld_multi.log [mysqld3306] basedir = /data/mysql57 mysqladmin=mysqladmin datadir=/data/mysql3306/data port=3306 server_id=102473306 socket= /tmp/mysql_3306.sock tmpdir = /data/mysql3306/tmp pid-file = /data/mysql3306/mysql_log/mysql3306.pid slow_query_log_file = /data/mysql3306/mysql_log/mysql3306_slow_new.log log-error = /data/mysql3306/mysql_log/mysql3306.err general_log_file= /data/mysql3306/mysql_log/mysql3306.genlog log-bin = /data/mysql3306/mysql_log/mysql3306_bin relay_log = /data/mysql3306/mysql_log/relay3306.log [mysqldump] quick step 5 . 初始化实例 初始化3306端口的实例，注意产生的临时密码。 /data/mysql57/bin/mysqld --defaults-file=/etc/my.cnf --initialize --user=mysql --basedir=/data/mysql57 --datadir=/data/mysql3306/data 初始化3307端口的实例，注意产生的临时密码。 （编辑：晋中站长网） 【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! |
