一、下载MySQL
MySQL下载地址
二、安装mysql
2.1 MySQL安装
双击安装包
到此MySQL安装完成。
2.2 MySQL配置
2.2.1 环境变量配置
1. 打开终端,输入以下命令:
vim ~/.bash_profile
2. 按i 键,进入insert 模式,输入以下两行代码
export PATH=$PATH:/usr/local/mysql/bin # mysql安装目录中的bin目录路径 export PATH=$PATH:/usr/local/mysql/support-files
最后按
3. 回到终端,输入以下命令
vim ~/.zshrc
4. 按i 键,进入insert 模式,输入以下两行代码
export PATH=$PATH:/usr/local/mysql/bin # mysql安装目录中的bin目录路径 export PATH=$PATH:/usr/local/mysql/support-files #mysql服务器配置文件(启动、关闭..)存放地址
5. 在终端执行如下命令
source ~/.zshrc source ~/.bash_profile
上述命令用于重新加载当前用户的 Zsh shell 配置文件
.zshrc 和Bash shell 配置文件.bash_profile 。执行这个命令后,新的配置将立即生效,而无需重新启动终端。
2.2.2 配置文件的创建
①在Windows下的Mysql中,安装目录修改my.ini文件就会对默认字符集进行配置
②而在Mac下,默认没有配置文件,需要自己手动创建
my.cnf 文件来配置
1. 创建 my.cnf文件
在终端输入
sudo vim /etc/my.cnf
系统提示输入电脑密码,之后进入输入模式,按i键,输入以下内容(不需要做任何修改):
# 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 max_allowed_packet = 1M 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 # 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! # #skip-networking # 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 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates default-character-set=utf8 [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout

2. 修改my.cnf读写权限
在终端输入如下代码:
sudo chmod 664 /etc/my.cnf
3. 在系统设置的MySQL面板中设置配置文件
当安装MySQL后没有在控制面板指定配置文件,使用
Navicat 连接服务器时会报2002 错误
