mysql5.7.17安装配置

一、创建msql用户

#添加运行mysql的用户，禁止该用户登录系统[root@openstack-01 ~]# useradd  mysql -s /sbin/nologin

二、创建相关目录

#创建目录[root@openstack-01 ~]# mkdir /data/mysql/mysql3306/{conf,data,logs,tmp} -p#修改目录权限[root@openstack-01 ~]# chown -R mysql.mysql /data/mysql

三、创建配置文件

[root@openstack-01 ~]# cat /data/mysql/mysql3306/conf/mysql_3306.cnf #my.cnf[client]port            = 3306socket          = /tmp/mysql3306.sock[mysql]prompt="\\u@\\h [\\d]>" #pager="less -i -n -S"#tee=/opt/mysql/query.logno-auto-rehash[mysqld]#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 = 1relay-log=relay-binrelay-log-index=relay-bin.indexlog_slave_updates#slave-skip-errors=1032,1053,1062#skip-grant-tables#buffers & cachetable_open_cache = 2048table_definition_cache = 2048table_open_cache = 2048max_heap_table_size = 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 = 2innodb_log_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

四、初始化mysql

#开始初始化[root@openstack-01 ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysqld --defaults-file=/data/mysql/mysql3306/conf/mysql_3306.cnf --basedir=/usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/ --initialize#查看初始化后的结果[root@openstack-01 ~]# ll /data/mysql/mysql3306/data/total 409648-rw-r----- 1 mysql mysql        56 Jun 10 17:27 auto.cnf-rw-r----- 1 mysql mysql      6236 Jun 10 17:27 error.log-rw-r----- 1 mysql mysql       413 Jun 10 17:27 ib_buffer_pool-rw-r----- 1 mysql mysql 104857600 Jun 10 17:27 ibdata1-rw-r----- 1 mysql mysql 104857600 Jun 10 17:27 ib_logfile0-rw-r----- 1 mysql mysql 104857600 Jun 10 17:27 ib_logfile1-rw-r----- 1 mysql mysql 104857600 Jun 10 17:27 ib_logfile2drwxr-x--- 2 mysql mysql      4096 Jun 10 17:27 mysqldrwxr-x--- 2 mysql mysql      8192 Jun 10 17:27 performance_schema-rw-r----- 1 mysql mysql       217 Jun 10 17:27 slow.logdrwxr-x--- 2 mysql mysql      8192 Jun 10 17:27 sys#获取root用户密码[root@openstack-01 ~]# grep password /data/mysql/mysql3306/data/error.log |awk '{print $11}'_:;II,r0I;oo

五、启动mysql
