1.安装 Composer

https://www.yiichina.com/doc/guide/2.0/start-installation
通过 Composer 安装

curl -sS https://getcomposer.org/installer | php

mv composer.phar /usr/local/bin/composer

解决方案

sudo vim /etc/php/7.2/cli/php.ini

zlib.output_compression = ON

安装成功

2.安装yii2 高级版

安装yii2

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

报错：

更换源：

composer config repo.packagist composer https://packagist.phpcomposer.com

报错：

加参数-g global

composer config -g  repo.packagist composer https://packagist.phpcomposer.com

---

再次安装yii2

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

更改网络连接方式，桥接方式

安装php-mbstring

sudo apt-get install php-mbstring

报网络连接超时

在浏览器打开安装包地址
http://ppa.launchpad.net/ondrej/php/ubuntu/pool/main/p/php7.2/php7.2-mbstring_7.2.9-1+ubuntu16.04.1+deb.sury.org+1_amd64.deb
不能访问，
发现另外一个复制的虚拟机也打开了，怀疑是IP地址冲突，关掉另外一台虚拟机后，可以打开这个地址

---

再次安装，报错：

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

执行：sudo apt-get install phpunitsudo apt-get install php7.2-xml

再次安装，安装成功

composer create-project --prefer-dist yiisoft/yii2-app-advanced yii-application

3.配置nginx

sudo vim /etc/nginx/sites-available/default

server {

        charset utf-8;

        client_max_body_size 128M;

        listen 80; ## listen for ipv4

        #listen [::]:80 default_server ipv6only=on; ## listen for ipv6

        server_name frontend.test;

        root        /home/jay/yii-application/frontend/web/;

        index       index.php;

        access_log  /home/jay/yii-application/log/frontend-access.log;

        error_log   /home/jay/yii-application/log/frontend-error.log;

        location / {

            # Redirect everything that isn't a real file to index.php

            try_files $uri $uri/ /index.php$is_args$args;

        }

        # uncomment to avoid processing of calls to non-existing static files by Yii

        #location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {

        #    try_files $uri =404;

        #}

        #error_page 404 /404.html;

        # deny accessing php files for the /assets directory

        location ~ ^/assets/.*\.php$ {

            deny all;

        }

        location ~ \.php$ {

            include fastcgi_params;

            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

            fastcgi_pass 127.0.0.1:9000;

            #fastcgi_pass unix:/var/run/php5-fpm.sock;

            try_files $uri =404;

        }

        location ~* /\. {

            deny all;

        }

    }

    server {

        charset utf-8;

        client_max_body_size 128M;

        listen 80; ## listen for ipv4

        #listen [::]:80 default_server ipv6only=on; ## listen for ipv6

        server_name backend.test;

        root        /home/jay/yii-application/backend/web/;

        index       index.php;

        access_log  /home/jay/yii-application/log/backend-access.log;

        error_log   /home/jay/yii-application/log/backend-error.log;

        location / {

            # Redirect everything that isn't a real file to index.php

            try_files $uri $uri/ /index.php$is_args$args;

        }

        # uncomment to avoid processing of calls to non-existing static files by Yii

        #location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {

        #    try_files $uri =404;

        #}

        #error_page 404 /404.html;

        # deny accessing php files for the /assets directory

        location ~ ^/assets/.*\.php$ {

            deny all;

        }

        location ~ \.php$ {

            include fastcgi_params;

            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

            fastcgi_pass 127.0.0.1:9000;

            #fastcgi_pass unix:/var/run/php5-fpm.sock;

            try_files $uri =404;

        }

        location ~* /\. {

            deny all;

        }

    }

重启nginx

sudo service nginx reload

sudo service nginx restart

查看错误日志

journalctl -xe

文件不存在
"/home/jay/yii-application/log/frontend-access.log" failed (2: No such file or directory)

解决方案：创建一个log文件夹

nignx 403

解决方案：初始化yii-application

~/yii-application$ php init

配置hosts

打开http://backend.test
报错502

安装php-fpm
sudo apt-get install php7.2-fpm

php-fpm监听地址有问题，需要与nginx监听地址一致 127.0.0.1:9000
sudo vim /etc/php/7.2/fpm/pool.d/www.conf

重启php7.2-fpm

sudo service php7.2-fpm restart

打开http://backend.test 跳转到login页面

http://frontend.test/ 跳转到欢迎页面

check php info
在/home/jay/yii-application/frontend/web 目录创建一个test.php文件

运行http://frontend.test/test.php

4.配置mysql

check mysql 服务是否打开，有localhost:mysql则表示服务已打开

sudo netstat -tap | grep mysql

start service

/etc/init.d/mysql start

stop service

/etc/init.d/mysql stop

连接mysql

mysql -u root -p

报错

切换到root用户

sudo su root

连接mysql，连接成功

mysql -u root -p

查看有哪些数据库

mysql> show databases

查看yii2 配置的数据库：

创建 yii2advanced数据库

mysql> create database yii2advanced

登陆报错，php mysql driver没有安装

安装php mysql 扩展

sudo apt-get install php7.2-mysql

再次登陆，报错：

SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost'

修改用户名密码

mysql -u root -p yii2advanced

mysql> select plugin from mysql.user where user = 'root';

mysql>  update mysql.user set plugin='mysql_native_password';

mysql> UPDATE mysql.user SET authentication_string=PASSWORD('abc123_') WHERE user='root';

mysql>  flush privileges;

mysql>  exit

再次连接mysql

 mysql -u root -p yii2advanced

输入abc123_
登陆成功

#5. 访问数据库
login
报 The table does not exist: {{%user}} 未找到
创建user表

CREATE TABLE IF NOT EXISTS `user`(

  `id` INT UNSIGNED AUTO_INCREMENT,

  `status` varchar (100),

  `username` varchar (100),

  `password` varchar (50),

  `email` varchar (50),

  `password_hash` varchar (200),

  `password_reset_token` varchar (200),

  `auth_key` varchar (50),

  `created_at` varchar (50),

  `updated_at` varchar (50),

  PRIMARY KEY (`id`)

)ENGINE=InnoDB DEFAULT CHARSET=utf8;

注册报错：

Setting unknown property: common\models\User::password_hash

gii生成代码
http://127.0.0.1/index.php?r=gii

报错：

Unable to write the file /yii-application/backend/models/Test.php'.

设置权限

sudo chmod -R 0777 backend

CURD

生成成功

查看文件目录

访问http://backend.test/index.php?r=test/index

phpMyAdmin 查询user表报错

$ sudo vim /usr/share/phpmyadmin/libraries/sql.lib.php
找到

(count($analyzed_sql_results['select_expr'] == 1)
1
改成和下面这句话一样就可以了～

(count($analyzed_sql_results['select_expr']) == 1

注册，登陆成功

数据插入到数据库里面了
