mysql如何实现下载安装配置及编码设置-创新互联
小编给大家分享一下mysql如何实现下载安装配置及编码设置，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！
一、下载mysql
最简单方法，直接输入命令：sudo apt-get install mysql-server。装完已经自动配置好环境变量，可以直接使用mysql的命令。
下载安装过程中会提示输入用户名和密码，非常easy!
注：建议将/etc/apt/source.list中的cn改成us，美国的服务器比中国的快很多。
二、配置mysql
1、启动mysql
2、在mydql>中输入：show variables like 'character%'; 查看编码
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | latin1 |
| character_set_connection | latin1 |
| character_set_database | latin1 |
| character_set_results | latin1 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
3、设置为utf8mb4编码（生产上多用次编码）
a、 控制台命令：locate my.cnf 查找mysql配置文件：my.cnf
b、 编辑 my.cnf 文件如下（红色为本人改动）：
[client]
port = 3306
socket = /var/run/mysqld/mysqld.sock
default-character-set = utf8mb4# Here is entries for some specific programs
# The following values assume you have at least 32M ram# This was formally known as [safe_mysqld]. Both versions are currently parsed.
[mysqld_safe]
socket = /var/run/mysqld/mysqld.sock
nice = 0[mysqld]
character-set-client-handshake = FALSE
character-set-server = utf8mb4
collation-server = utf8mb4_unicode_ci
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address = 0.0.0.0
"/etc/mysql/my.cnf" [readonly] 132L, 3675C
4、重启mysql(非常重要)
5、测试配置
在mydql>中输入：show variables like 'character%'; 查看编码应该如下：
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8mb4 |
| character_set_connection | utf8mb4 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | utf8mb4 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
四、修改Xshell编码
1、修改连接编码
xshell中选中要连接的会话=>右击选“属性”=>类别选“终端”=>编码下拉选“unicodeutf-8”=>确定
2、修改Xshell工具栏上“编码”按钮，选择“utf8”
五、修改ubuntu编码
1、查看服务器编码，命令行输入：locale
LANG=zh_CN.UTF-8
LANGUAGE=zh_CN:zh
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC=zh_CN
LC_TIME=zh_CN
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY=zh_CN
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER=zh_CN
LC_NAME=zh_CN
LC_ADDRESS=zh_CN
LC_TELEPHONE=zh_CN
LC_MEASUREMENT=zh_CN
LC_IDENTIFICATION=zh_CN
LC_ALL=
2、修改服务器编码
a、使用管理员权限进入/etc/default/
b、使用vi编辑文件:locale 如下：
LANG="en_US.UTF-8"
LANGUAGE="en_US:"
~
~
3、重启服务器（虚拟机）
4、再次查看服务器编码、命令行输入：locale
LANG=en_US.UTF-8
LANGUAGE=en_US:
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=
全部设置为utf-8 成功。
通过以上五部设置，所有编码都设置为统一utf8，就可以再Xshell中输入中文，mysql中也可以输入中文，全部搞定！
