3、修改/etc/my.cnf

    [client]
    #password       = your_password
    port            = 3309
    socket          = /tmp/mysql.sock
    
    # Here follows entries for some specific programs
    
    # The MySQL server
    [mysqld]
    
    user = hc
    port            = 3309
    socket          = /tmp/mysql.sock
    pid-file		= /usr/local/mysql/mysqld.pid
    skip-external-locking
    slave-net-timeout = 60
    #log_slave_update = 1
    #skip-grant-tables
    
    sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
    key_buffer_size = 256M
    max_allowed_packet = 512M
    table_open_cache = 2048
    sort_buffer_size = 16M
    read_buffer_size = 16M
    read_rnd_buffer_size = 16M
    myisam_sort_buffer_size = 16M
    thread_cache_size = 64
    join_buffer_size = 16M

    innodb_open_files = 3000
    #table_cache = 4096
    innodb_log_file_size = 256M
    
    # Try number of CPU's*2 for thread_concurrency
    #thread_concurrency = 2
    
    lower_case_table_names = 1

    character_set_server = utf8
    max_connections = 5000

    datadir = /data/mysqldata
    log-error = /data/logs/mysql/mysqld.log

    [mysqldump]
    quick
    max_allowed_packet = 512M
    
    [mysql]

    sort_buffer_size = 128M
    read_buffer = 2M
    write_buffer = 2M
    
    [mysqlhotcopy]
    interactive-timeout

4、启动

service mysqld restart

5、加入启动项目

   

systemctl enable   mysqld

5、设置root密码

mysql -uroot 
mysql> set password for ‘root'@‘localhost' = password('mypasswd');

6、创建数据库并指定utf-8编码

mysql> CREATE DATABASE xxxx DEFAULT CHARSET utf8 COLLATE utf8_general_ci

7、导入数据库

    mysql>use 数据库 
    -- 然后使用source命令，后面参数为脚本文件(如这里用到的.sql) 
    mysql>source dbname.sql
