一、CMake安装
Ubuntu Linux 下安装和卸载cmake 3.28.2版本-CSDN博客
https://blog.csdn.net/weixin_41987016/article/details/135960115?spm=1001.2014.3001.5501二、安装boost
boost官网：boost官网
我下载的boost版本：
- windows:boost_1_84_0.zip
- linux:boost_1_84_0.tar.gz
2.1 在windows中安装boost和测试
（1）在windows中，解压这个压缩包boost_1_84_0.zip，路径为：D:\boost_1_84_0
- 在这个路径下有一个文件的文件名是bootstrap.bat:
运行cmd,切换到D:\boost_1_84_0这个路径，然后D:\boost_1_84_0>bootstrap.bat
（2）接着执行
.\b2（3）生成b2.exe文件，默认执行b2.exe
D:\boost_1_84_0>b2.exe
（4）打开visual stdio 2022,在创建好的C++项目中，点击项目>属性>VC++目录这里添加路径到包含目录和库目录
- 包含目录
D:\boost_1_84_0- 库目录
D:\boost_1_84_0\stage\lib
- main.cpp
#include <iostream>
#include <boost/bind.hpp>
#include <string>
using namespace std;class Person {
public:void say(string name) {cout << name << "说: 三弟你真可爱!" << endl;}
};int main() {Person h;auto func = boost::bind(&Person::say, &h, "关羽");func();return 0;
}
至此，成功验证！！！
2.2 在Linux中安装boost和测试
heheda@linux:~$ cd ~
heheda@linux:~$ pwd
/home/heheda
heheda@linux:~$ mkdir package
heheda@linux:~$ ls
examples.desktop Linux llvm.sh package projects vim配置 公共的 模板 视频 图片 文档 下载 音乐 桌面将boost_1_69_0.tar.gz 用 FinalShell等上传文件工具，上传到/home/heheda/package这个目录下
heheda@linux:~$ cd package/
heheda@linux:~/package$ ls
boost_1_84_0.tar.gz
heheda@linux:~/package$ tar -zxvf boost_1_69_0.tar.gz
heheda@linux:~/package$ ls
boost_1_84_0 boost_1_84_0.tar.gz
heheda@linux:~/package$ cd boost_1_84_0
heheda@linux:~/package/boost_1_84_0$ ./bootstrap.sh
heheda@linux:~/package/boost_1_84_0$ ./b2
heheda@linux:~/package/boost_1_84_0$ ./b2 install
打开visual stdio 2022,选择Linux，选择控制台应用程序
- 工具>选项>跨平台>连接管理器
打开visual stdio 2022,在创建好的C++项目中，点击项目>属性>VC++目录这里添加路径到包含目录和库目录
- 包含目录
/home/heheda/package/boost_1_84_0- 库目录
/home/heheda/package/boost_1_84_0/stage/lib

heheda@linux:~/package/muduo-master$ vim CMakeLists.txt 按下i键，注释掉这一行。按ESC键，然后:wq实现保存退出
- 注意：muduo是用cmake来构建的，所以要先安装cmake

测试代码：参考和推荐这篇文章：

另外，我们也可以在visual stdio 2022来测试muduo是否安装成功。点击项目>属性>链接器>输入>库依赖项
muduo_net
muduo_base
pthread
至此，muduo安装成功，开始正常进行C++网络程序开发♪(^∇^*)啦！！！
四、安装mysql
sudo apt-get install mysql-server =>安装最新版MYSQL服务器
sudo apt-get install libmysqlclient-dev => 安装开发包
ubuntu默认安装最新的mysql，但是初始的用户名和密码是自动生成的，按下面步骤修改mysql的root和用户密码为123456
sudo cat /etc/mysql/debian.cnf
命令解释：-u后面是上面查看的用户名 -p后面紧跟上面查看的密码
sudo mysql -u debian-sys-maint -pXGxB5JwQHPIJuwPw
mysql> update mysql.user set authentication_string=password('123456') where user='root' and host='localhost';
mysql> update mysql.user set plugin='mysql_native_password';
mysql> flush privileges;
mysql> quit;
- 重新启动 mysql
heheda@linux:~$ sudo service mysql restart
输入设置好的密码：123456
设置编码：vim /etc/mysql/mysql.conf.d/mysqld.cnf
在最后添加一句：
character-set-server=utf8
查看字符编码
mysql> show variables like 'character_set_%';
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | utf8 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
