Mysql5.7.17 installation configuration

First, create msql users

# add a user running mysql, and prohibit the user from logging in to the system [root@openstack-01 ~] # useradd mysql-s / sbin/nologin

Create relevant catalogs

# create directory [root@openstack-01 ~] # mkdir / data/mysql/mysql3306/ {conf,data,logs,tmp}-p# modify directory permissions [root@openstack-01 ~] # chown-R mysql.mysql / data/mysql

Third, create a configuration file

[root@openstack-01 ~] # cat / data/mysql/mysql3306/conf/mysql_3306.cnf # my.cnf [client] port = 3306socket = / tmp/ MySQL 3306 sock [MySQL] prompt= "\ u @\\ h [\ d] >" # pager= "less-I-n-S" # tee=/opt/mysql/query.logno-auto-rehash [client] # miscuser = mysqlbasedir = / usr/local/mysqldatadir = / data/mysql/mysql3306/dataport = 3306socket = / tmp/mysql3306.sockevent_scheduler = 0tmpdir = / data/mysql/mysql3306/tmp#timeoutinteractive_timeout = 300wait_timeout = 300#character setcharacter-set-server = utf8open_files_limit = 65535max_connections = 100max_connect_errors = 100000lower_case_table_names = 1#symi replication#rpl_semi_sync_master_enabled=1#rpl_semi_sync_master_timeout=1000 # 1 second#rpl_semi_sync_slave_enabled=1#logslog-output=fileslow_query_log = 1slow_query_log_file = slow.loglog-error = error.loglog_warnings = 2pid-file = mysql.pidlong_query_time = 1#log-slow-admin-statements = 1#log-queries-not-using-indexes = 1log-slow-slave-statements = 1#binlog#binlog_format = STATEMENTbinlog_format = rowserver-id = 1003306log-bin = / data/mysql/mysql3306/logs/mysql-binmax_binlog_size = 256Msync_binlog = 0expire_logs_days = 10#procedure log_bin_trust_function_creators=1#gtid-mode = onenforce-gtid-consistency=1#relay Logskip_slave_start = 1max_relay_log_size = 128Mrelay_log_purge = 1relay_log_recovery = 1relayMutholink = 128Mrelay_log_purge = 1relay_log_recovery = 1relayMill Lorente = 96Msort_buffer_size = 128Kjoin_buffer_size = 128Kthread_cache_size = 200query_cache_size = 0query_cache_type = 0query_cache_limit = 256Kquery_cache_min_res_unit = 512thread_stack = 192Ktmp_table_size = 96Mkey_buffer_size = 8Mread_buffer_size = 2Mread_rnd_buffer_size = 16Mbulk_insert_buffer_size = 32M#myisammyisam_sort_buffer_size = 128Mmyisam_max_sort_file_size = 10Gmyisam_repair_threads = 1#innodbinnodb_buffer_pool_size = 100Minnodb_buffer_pool_instances = 1innodb_data_file_path = ibdata1:100M:autoextendinnodb_flush_log_at_trx_commit = 2innodbaccountlog_ Buffer_size = 8Minnodb_log_file_size = 100Minnodb_log_files_in_group = 3innodb_max_dirty_pages_pct = 50innodb_file_per_table = 1innodb_rollback_on_timeoutinnodb_io_capacity = 2000transaction_isolation = READ-COMMITTEDinnodb_flush_method = O_DIRECT
