# 1. 为FISCO配置MySQL参数 #

1. 打开终端，输入如下语句查看mysql加载的是哪个配置文件：

mysql --verbose --help | grep my.cnf

显示如下输出：

2. 在终端创建/etc/my.cnf文件，如下：

cd /etc
    sudo vim my.cnf

3. 在新建的my.cnf文件中加入如下内容（直接复制粘贴即可）：

# Example MySQL config file for medium systems.
    #
    # This is for a system with little memory (32M - 64M) where MySQL plays
    # an important part, or systems up to 128M where MySQL is used together with
    # other programs (such as a web server)
    #
    # MySQL programs look for option files in a set of
    # locations which depend on the deployment platform.
    # You can copy this option file to one of those
    # locations. For information about these locations, see:
    # http://dev.mysql.com/doc/mysql/en/option-files.html
    #
    # In this file, you can use all long options that a program supports.
    # If you want to know which options a program supports, run the program
    # with the "--help" option.
    # The following options will be passed to all MySQL clients
    [client]
    default-character-set=utf8
    #password = your_password
    port = 3306
    socket = /tmp/mysql.sock
    # Here follows entries for some specific programs
    # The MySQL server
    [mysqld]
    character-set-server=utf8
    init_connect='SET NAMES utf8
    port = 3306
    socket = /tmp/mysql.sock
    skip-external-locking
    key_buffer_size = 16M
    # FISCO相关参数 -- 开始 --
    max_allowed_packet = 1024M
    sql_mode =STRICT_TRANS_TABLES
    ssl=0
    default_authentication_plugin = mysql_native_password
    # FISCO相关参数 -- 结束 --
    table_open_cache = 64
    sort_buffer_size = 512K
    net_buffer_length = 8K
    read_buffer_size = 256K
    read_rnd_buffer_size = 512K
    myisam_sort_buffer_size = 8M
    character-set-server=utf8
    init_connect='SET NAMES utf8'
    # Don't listen on a TCP/IP port at all. This can be a security enhancement,
    # if all processes that need to connect to mysqld run on the same host.
    # All interaction with mysqld must be made via Unix sockets or named pipes.
    # Note that using this option without enabling named pipes on Windows
    # (via the "enable-named-pipe" option) will render mysqld useless!
    #

    # Replication Master Server (default)
    # binary logging is required for replication
    log-bin=mysql-bin
    
    # binary logging format - mixed recommended
    binlog_format=mixed
    
    # required unique id between 1 and 2^32 - 1
    # defaults to 1 if master-host is not set
    # but will not function as a master if omitted
    server-id = 1
    
    # Replication Slave (comment out master section to use this)
    #
    # To configure this host as a replication slave, you can choose between
    # two methods :
    #
    # 1) Use the CHANGE MASTER TO command (fully described in our manual) -
    # the syntax is:
    #
    # CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
    # MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
    #
    # where you replace <host>, <user>, <password> by quoted strings and
    # <port> by the master's port number (3306 by default).
    #
    # Example:
    #
    # CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
    # MASTER_USER='joe', MASTER_PASSWORD='secret';
    #
    # OR
    #
    # 2) Set the variables below. However, in case you choose this method, then
    # start replication for the first time (even unsuccessfully, for example
    # if you mistyped the password in master-password and the slave fails to
    # connect), the slave will create a master.info file, and any later
    # change in this file to the variables' values below will be ignored and
    # overridden by the content of the master.info file, unless you shutdown
    # the slave server, delete master.info and restart the slaver server.
    # For that reason, you may want to leave the lines below untouched
    # (commented) and instead use CHANGE MASTER TO (see above)
    #
    # required unique id between 2 and 2^32 - 1
    # (and different from the master)
    # defaults to 2 if master-host is set
    # but will not function as a slave if omitted
    #server-id = 2
    #
    # The replication master for this slave - required
    #master-host = <hostname>
    #
    # The username the slave will use for authentication when connecting
    # to the master - required
    #master-user = <username>
    #
    # The password the slave will authenticate with when connecting to
    # the master - required
    #master-password = <password>
    #
    # The port the master is listening on.
    # optional - defaults to 3306
    #master-port = <port>
    #
    # binary logging - not required for slaves, but recommended
    #log-bin=mysql-bin
    
    # Uncomment the following if you are using InnoDB tables
    #innodb_data_home_dir = /usr/local/mysql/data
    #innodb_data_file_path = ibdata1:10M:autoextend
    #innodb_log_group_home_dir = /usr/local/mysql/data
    # You can set .._buffer_pool_size up to 50 - 80 %
    # of RAM but beware of setting memory usage too high
    #innodb_buffer_pool_size = 16M
    #innodb_additional_mem_pool_size = 2M
    # Set .._log_file_size to 25 % of buffer pool size
    #innodb_log_file_size = 5M
    #innodb_log_buffer_size = 8M
    #innodb_flush_log_at_trx_commit = 1
    #innodb_lock_wait_timeout = 50

4. 根据教程指示尝试在终端重启mysql，即输入如下语句：

sudo mysql.server restart

产生报错：

![20210108114649287.png][]

错误原因似乎是mac上无法通过命令行启动和停止mysql服务。需要从“系统偏好设置 -> MySQL”里面点击启动和停止。 于是从系统偏好设置里stop -> start，完成。

5. 验证刚刚配置的参数。首先在终端输入如下语句：

mysql -uroot -p

然后在mysql模式下输入如下图红线标识语句，查看参数：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbW1lbF85Mg_size_16_color_FFFFFF_t_70][]

本次操作查看的是max\_allowed\_packet参数和sql\_mode参数。注意mysql> 里输入的语句要以“；”结束，不然mysql不认。

2. 查看
