一、创建msql用户
#添加运行mysql的用户，禁止该用户登录系统 [[email protected] ~]# useradd mysql -s /sbin/nologin
二、创建相关目录
#创建目录
[[email protected] ~]# mkdir /data/mysql/mysql3306/{conf,data,logs,tmp} -p
#修改目录权限
[[email protected] ~]# chown -R mysql.mysql /data/mysql
三、创建配置文件
[[email protected] ~]# cat /data/mysql/mysql3306/conf/mysql_3306.cnf #my.cnf [client] port = 3306 socket = /tmp/mysql3306.sock [mysql] prompt="\\[email protected]\\h [\\d]>" #pager="less -i -n -S" #tee=/opt/mysql/query.log no-auto-rehash [mysqld] #misc user = mysql basedir = /usr/local/mysql datadir = /data/mysql/mysql3306/data port = 3306 socket = /tmp/mysql3306.sock event_scheduler = 0 tmpdir = /data/mysql/mysql3306/tmp #timeout interactive_timeout = 300 wait_timeout = 300 #character set character-set-server = utf8 open_files_limit = 65535 max_connections = 100 max_connect_errors = 100000 lower_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 #logs log-output=file slow_query_log = 1 slow_query_log_file = slow.log log-error = error.log log_warnings = 2 pid-file = mysql.pid long_query_time = 1 #log-slow-admin-statements = 1 #log-queries-not-using-indexes = 1 log-slow-slave-statements = 1 #binlog #binlog_format = STATEMENT binlog_format = row server-id = 1003306 log-bin = /data/mysql/mysql3306/logs/mysql-bin max_binlog_size = 256M sync_binlog = 0 expire_logs_days = 10 #procedure log_bin_trust_function_creators=1 # gtid-mode = on enforce-gtid-consistency=1 #relay log skip_slave_start = 1 max_relay_log_size = 128M relay_log_purge = 1 relay_log_recovery = 1 relay-log=relay-bin relay-log-index=relay-bin.index log_slave_updates #slave-skip-errors=1032,1053,1062 #skip-grant-tables #buffers & cache table_open_cache = 2048 table_definition_cache = 2048 table_open_cache = 2048 max_heap_table_size = 96M sort_buffer_size = 128K join_buffer_size = 128K thread_cache_size = 200 query_cache_size = 0 query_cache_type = 0 query_cache_limit = 256K query_cache_min_res_unit = 512 thread_stack = 192K tmp_table_size = 96M key_buffer_size = 8M read_buffer_size = 2M read_rnd_buffer_size = 16M bulk_insert_buffer_size = 32M #myisam myisam_sort_buffer_size = 128M myisam_max_sort_file_size = 10G myisam_repair_threads = 1 #innodb innodb_buffer_pool_size = 100M innodb_buffer_pool_instances = 1 innodb_data_file_path = ibdata1:100M:autoextend innodb_flush_log_at_trx_commit = 2 innodb_log_buffer_size = 8M innodb_log_file_size = 100M innodb_log_files_in_group = 3 innodb_max_dirty_pages_pct = 50 innodb_file_per_table = 1 innodb_rollback_on_timeout innodb_io_capacity = 2000 transaction_isolation = READ-COMMITTED innodb_flush_method = O_DIRECT
四、初始化mysql
#开始初始化
[[email protected] ~]# /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
[[email protected] ~]# ll /data/mysql/mysql3306/data/
total 409648
-rw-r----- 1 mysql mysql 56 Jun 10 17:27 auto.cnf

#获取root用户密码
[[email protected] ~]# grep password /data/mysql/mysql3306/data/error.log |awk ‘{print $11}‘

五、启动mysql
[[email protected] ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysqld --defaults-file=/data/mysql/mysql3306/conf/mysql_3306.cnf & [1] 14632 [[email protected] ~]# ps aux |grep mysql |grep -v grep mysql 14632 2.7 9.8 1067652 184596 pts/0 Sl 17:30 0:00 /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysqld --defaults-file=/data/mysql/mysql3306/conf/mysql_3306.cnf [[email protected] ~]# ss -tnl |grep 3306 LISTEN 0 70 :::3306 :::* #登录mysql [[email protected] ~]# /usr/local/mysql-5.7.17-linux-glibc2.5-x86_64/bin/mysql -u root -p -S /tmp/mysql3306.sock Enter password: #输入上文中获取到的密码 Welcome to the MySQL monitor.
