linux 环境配置

#linux 环境配置

不知道怎么设置cmake，没有配出asio与boost asio 共存CMakeLists.txt

如果你安装了boost asio 那么需要指定独立的asio地址，把独立asio放到paozhu项目下面,后面讲这么拷贝。 框架目录下有一个asio.zip压缩包，新版兼容openssl3.0

vendor

view

asio

• asio.hpp
• asio

类似这样子

#安装 gcc

 $ sudo apt update
 $ sudo apt install build-essential

本文以ubuntu20.04 安装为蓝本，ubuntu22.04 应该默认是 gcc-11 ubuntu22可以跳过gcc11安装 所以直接 sudo apt install build-essential 可以安装好gcc-11

sudo add-apt-repository -y ppa:ubuntu-toolchain-r/test

sudo apt install -y gcc-11
sudo apt install -y g++-11

gcc-11 --version
g++-11 -v

可以不安装gcc-10 sudo apt install gcc-10 //可能没有gcc-11 sudo apt install g++-10

 $ sudo apt-get install manpages-dev	   
 $ sudo apt-get install libboost-dev   //动态库用到 libboost-all-dev

 $ sudo apt install libboost-filesystem-dev

 $ sudo apt install git
 $ sudo apt install cmake  

如果是 Fedora 系统需要，这样才能编译上 -fsanitize=address

 $ sudo yum install libasan

安装依赖库

sudo apt install brotli 
sudo apt install libgd-dev
sudo apt install qrencode libqrencode-dev

sudo apt-get install openssl libssl-dev

也可以在框架根目录写一个测试文件testasio.cpp

$ g++ testasio.cpp

testasio.cpp

#include "asio/asio.hpp"
#include <iostream>

int main(){
	std::cout<<ASIO_VERSION<<std::endl;
	return 0;
}

应该输出,最好用asio 1.28以上 102800

安装mysql8

参考 https://zhuanlan.zhihu.com/p/262721133 https://naturetrible.blog.csdn.net/article/details/122030359

sudo apt-get install mysql-server
sudo apt-get install mysql-common
sudo apt-get install mysql-client
sudo apt-get install libmysqlclient-dev

sudo service mysql status # 查看服务状态
sudo service mysql start # 启动服务
sudo service mysql stop # 停止服务
sudo service mysql restart # 重启服务


$ sudo service mysql status

查看密码 List first password

$ sudo cat /etc/mysql/debian.cnf
# Automatically generated for Debian scripts. DO NOT TOUCH!
[client]
host     = localhost
user     = debian-sys-maint
password = 5hiIbvxR2DgC7ekz
socket   = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host     = localhost
user     = debian-sys-maint
password = 5hiIbvxR2DgC7ekz
socket   = /var/run/mysqld/mysqld.sock

登陆加root密码
mysql -u debian-sys-maint -p

创建root用户

 create user 'root'@'%' identified by '12345678';

授权

 GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

刷新权限 FLUSH PRIVILEGES

修改密码，注意如果是生产环境不要用12345678

 ALTER user 'root'@'localhost' IDENTIFIED BY '12345678';
 ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '12345678';

我们去验证是不是设置上密码了

选择mysql库看一有用户

use mysql;
select host,user,authentication_string from user;
+-----------+------------------+------------------------------------------------------------------------+
| host      | user             | authentication_string                                                  |
+-----------+------------------+------------------------------------------------------------------------+
| %         | root             | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
| localhost | debian-sys-maint | $A$005$*HO7jVD!i#
                                                  g4FuU2y95DdV87pa2WisukPk4JCFhEZ5R2zEnFWMzrc3e. |

| localhost | root             | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9                              |
+-----------+------------------+------------------------------------------------------------------------+

如果可以我们退出

mysql -u root -p 输入12345678 可以登陆了

如果是系统 Fedora38 数据库是 MariaDB 直接用root权限进去改密码

# systemctl start mariadb
# systemctl enable mariadb
# systemctl status mariadb
# sudo mysql -u root -p

我们写一个测试文件验证下

g++ mysqltest.cpp -std=c++20  -I/usr/include/mysql -lmysqlclient

mysqltest.cpp

#include <memory>
#include <iostream>
#include "mysql.h"
using std::cout;
using std::endl;


int main() {
        // 默认的安装方式端口是3306
        std::unique_ptr<MYSQL, decltype(&mysql_close)> conn(new MYSQL, &mysql_close);
        mysql_init(conn.get()); 
if(!mysql_real_connect(conn.get(),"127.0.0.1","root","12345678","mysql",3306,NULL,0))
            {
                std::cout<<"mysql db link error!"<<std::endl;
                std::cout<<mysql_error(conn.get())<<std::endl;
            } 
        cout <<"Done!" <<endl;   
}

现在已经安装完成所有需要基础软件
如果需要CRUD演示,还要导入conf目录下几个sql文件，参考ORM入门文章，可以稍后导入，接着继续往下。

asio1.22.1已经兼容openssl3了，所以ubuntu22.04 安装基础软件包应该没有那么困难，直接apt-get 安装就可以了

编译paozhu c++ web framework 框架 进入框架目录

mkdir build

cd build

cmake .. 

如果没有相应的包，去安装相应的包

make

配置服务器 conf 目录

server.conf 文件 把里面的路径配置成你的路径

然后回到 框架目录 运行

sudo ./bin/paozhu

需要80 等端口 必须管理员权限运行，打开浏览localhost可以看到也页面了。

---

============================================
到此你已经配置完毕，如果你想php后端可以往下设置。

##php-fpm 主要和配置##

sudo apt  install php-fpm php php-gd  
sudo systemctl restart php8.1-fpm  

修改 /etc/php/8.1/pool.d/www.conf
listen = 127.0.0.1:9000

user = 你用户名
group =你的组

netstat -an 看看有没有9000端口

编辑paozhu conf/server.conf文件

isuse_php=1
rewrite_php=/Users/hzq/Documents/www/thinkphp/public|index.php
fastcgi_host=127.0.0.1
fastcgi_port=9000

查看状态
sudo systemctl status php8.1-fpm

1 access denied 权限问题
使用chown -R 你用户名:你的组 目录
php.ini文件中
cgi.fix_pathinfo=1：将0 改为 1

2 File not found 或 Primary script unknown
php-fpm.conf 中的配置用户名
user = 你用户名
group =你的组
