关于MySQL安装程序，SQLyog安装程序及SQLyog的激活码我分享在下面了,有需要的取走自用就可以了

> (不知道为啥这次挂链接平台一直不通过,所以不挂了,需要链接给我说我会发的)

## MySQL ##

### 1.安装 ###

1.打开安装程序,进入如下界面,选中"custom(自定义安装)"

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 1]

2.按如下操作将MySQL Server 5.7.35 - X64加入到右侧空白区域(我的电脑是64位的,如果是32位就选X86的)

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 2]

3.鼠标点击选中的右侧的MySQL Server 5.7.35 - X64然后点击"Advanced Options"选择安装位置

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 3]

4.注意安装位置的目录必须是不存在的,需要让安装程序自己创建,否则就会出现警告

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_11_color_FFFFFF_t_70_g_se_x_16_pic_center]

5.第二个目录报错是因为我在data文件夹下创建了MySQL Server 5.7.35 - X64文件夹,当我把文件夹MySQL Server 5.7.35 - X64删去后就不会再出现警告了

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_11_color_FFFFFF_t_70_g_se_x_16_pic_center 1]

6.点击"OK"后回到了Select Products界面,此时勾选"Enable the…(启用选择功能页面用于自定义产品特性)“并发现左侧菜单栏出现了"Select Features To install”  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 4]

7.在Download界面执行下载,下载完成后点击"next"

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 5]  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 6]

8.可以把"Documentation(帮助文档)"取消勾选,这样的话就不会下载官方帮助文档了

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 7]

9.在Installation界面执行安装,安装完成后点击"next"

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 8]  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 9]

10.点击"next"进入配置界面

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 10]

11.直接"next"  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 11]

12.设置密码(账号默认是root)

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 12]

13.此时提醒我服务名被占用,原因是我这台电脑昨天重装系统后已经装过一次MySQL了,后来我卸载了,现在是第二次安装MySQL了,这个服务名在第一次安装时就设置了,目前还没有删除该服务名,所以这里会显示服务名被占用  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_19_color_FFFFFF_t_70_g_se_x_16_pic_center]

解决办法移步[删除计算机中的某项服务(解决重装MySQL等软件时服务名已存在的问题)][MySQL]  
没有出现这种情况的话接着进行14步

14.点击"Next",后面再出来的任何界面出现"Next"的点"Next",出现"Execute"的点"Execute",出现"Finish"的点"Finish",设置都是按照默认的就可以了,不需要做任何修改.最后会出现一个安装成功的界面,至此,MySQL下载安装完成

### 2.配置环境变量 ###

1.打开系统设置

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_7_color_FFFFFF_t_70_g_se_x_16_pic_center]

2.在搜索栏搜索"系统环境变量",然后点击出现的"编辑系统环境变量"

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_18_color_FFFFFF_t_70_g_se_x_16_pic_center]

3.在弹出的界面点击"环境变量"

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_10_color_FFFFFF_t_70_g_se_x_16_pic_center]

4.点击"系统变量"一栏的"新建"按钮.

> 这里建议环境变量不要配置到用户变量中,因为windows在执行用户命令时,若用户未给出文件的绝对路径,则首先在当前目录下寻找相应的可处理文件,批处理文件等;若找不到再依次在系统变量的PATH保存的这些路径中寻找相应的可执行文件,如果还找不到再去用户变量的PATH路径中寻找,所以系统变量中的路径会比用户变量中的路径先被系统搜寻,在一定程度上能加快运行速度

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_13_color_FFFFFF_t_70_g_se_x_16_pic_center]

5.变量名本着"见名知意"的原则起名为"MYSQL\_HOME"

![在这里插入图片描述][1ed9faf29839487fa3ee94bd183ed812.png_pic_center]

6.将电脑中存放MySQL的文件夹的路径复制粘贴在"变量值"中

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_14_color_FFFFFF_t_70_g_se_x_16_pic_center]  
![在这里插入图片描述][361f1f8dc3004f128cd107c856efc2af.png_pic_center]

7.找到"Path"双击进入

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_13_color_FFFFFF_t_70_g_se_x_16_pic_center 1]

![在这里插入图片描述][127e07dbe9404e598b0b5ac3c7623f36.png_pic_center]

8.为啥我的"Path"是在一行而别人的都是展开在一个新的界面呢

> 因为系统原本默认是"C:…",而我将连续两个%…%开头的变量移至了"Path"变量值的最前面(一个的话没问题,还是会展开的),所以造成了Path是在一行

解决办法:**拉到这个变量值的最后，然后剪切最后一个变量并粘贴到最前面**

剪切时注意不要少剪或多剪,一定是以百分号(%)开始,以分号(;)结尾的

![在这里插入图片描述][8ac699244881406eb4528ff9aa76ffe1.png_pic_center]

![在这里插入图片描述][5fcd676a948c4b6c9104efbfcd7ae316.png_pic_center]

9.此时再双击"Path"发现内容不再时展示在一行了,而是展示在一个新的界面了。在这个新的界面点击“新建”

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_11_color_FFFFFF_t_70_g_se_x_16_pic_center 2]

10.填入%MYSQL\_HOME%\\bin并依次点击“确定”。至此环境变量配置完毕

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_11_color_FFFFFF_t_70_g_se_x_16_pic_center 3]  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_13_color_FFFFFF_t_70_g_se_x_16_pic_center 2]  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_10_color_FFFFFF_t_70_g_se_x_16_pic_center 1]

### 3.验证环境变量是否正确 ###

1.在搜索框搜索“命令提示符”并右键选择”以管理员身份运行“  
![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_18_color_FFFFFF_t_70_g_se_x_16_pic_center 1]

2.既然要测试环境是否配置成功，那就需要先启动MySQL服务

2.1在命令行输入net start mysql

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_10_color_FFFFFF_t_70_g_se_x_16_pic_center 2]

2.2为什么显示服务名无效呢，如下所示，我们在安装MySQL时设置的服务名是mysql57，所以根本就没有mysql这个服务名

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_17_color_FFFFFF_t_70_g_se_x_16_pic_center 13]

2.3所以在命令行输入net start mysql57以启动服务

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_12_color_FFFFFF_t_70_g_se_x_16_pic_center]

2.4如果服务已经启动了则会显示“请求的服务已经启动”

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_15_color_FFFFFF_t_70_g_se_x_16_pic_center]

2.5输入mysql -uroot -p按下enter

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_11_color_FFFFFF_t_70_g_se_x_16_pic_center 4]

2.6此时提示输入密码，于是输入密码再次按下enter，如果能出现如下的信息，说明环境配置成功

![在这里插入图片描述][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6K6k55yf55Sf5rS755qE54Gw5aSq54u8_size_16_color_FFFFFF_t_70_g_se_x_16_pic_center]
