  1. unable to bind listening socket for address '/run/php/php7.1-fpm.sock' no such file or directory

原因：php-fpm 没有启动，如下启动：

# 启动命令：
sudo /etc/init.d/php7-fpm start
  1. 查看Ubuntu Apache2 服务器日志
tail -f /var/log/apache2/*.log

  1. remote-ssh

  2. 启动Apache2后打开php 网站报错

sudo apache2 start
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

有可能是php-fpm没有启动

sudo /etc/init.d/php7.3-fpm start
  1. MYSQL
# 启动mysql
sudo service mysql start

一直报错

-su: 30: export: : bad variable name

最终问题定位： 在/etc/profile 之前添加了如下语句

SET NODE_HOME=/opt/node10.16.0-linux-x64
PATH = $PAHT:NODE_HOME

删除上面自己添加的即可启动

  1. WSL 暂不支持 netstat ss 等命令

# 查看MYSQL数据库中所有用户
mysql> SELECT DISTINCT CONCAT('User: ''',user,'''@''',host,''';') AS query FROM mysql.user;

# 查看数据库中具体某个用户的权限
mysql> select * from mysql.user where user='singcl' \G    

#查看user表结构　需要具体的项可结合表结构来查询
mysql> desc mysql.user;
  1. 数据库操作相关问题

启动

# 1 启动apache2
sudo service apache2 start

# 2 启动php-fpm
sudo service php7.3-fpm start

# 3 启动mysql
sudo service mysql start
  1. PDO 相关问题
# 环境：Ubuntu 16.02

代码中使用PDO 时候返回 PDOException: can not find driver。 然后我们查看phpinfo() 确认下： PDO 显示：drivers no value

说明PDO 链接MYSQL 驱动找不到。

网上搜索这个问题，答案都是挺多的， 赞成数最多的方案：

# @see https://stackoverflow.com/questions/32728860/php-7-rc3-how-to-install-missing-mysql-pdo

# 第一步安装
apt-get install php7.3-mysql

#第二步 激活

# phpenmod@see https://tecadmin.net/enable-disable-php-modules-ubuntu/
phpenmod pdo_mysql

ln: failed to create symbolic link '/etc/php/7.3/cli/conf.d/20-pdo_mysql.ini': Permission denied
rm: cannot remove '/var/lib/php/modules/7.3/cli/disabled_by_admin/pdo_mysql': Permission denied

# 可以看出来这一步会在/etc/php/7.3/cli/conf.d/ 中创建一个符号链接 到/etc/php/7.3/mods-abailable/pdo_mysql.so
# 同时创建 /var/lib/php/modules/7.3/cli/enabled_by_admin/pdo_mysql

# 权限不够sudo
sudo phpenmod pdo_mysql
# 第三步 重启
sudo service apache2 restart

然后不幸的是还是失败了！！

我观察/etc/php/7.3中的目录 发现有个fpm。 fpm 和 cli 目录下都有php.ini 文件？

我的PHP 使用的是 apache2 fast-cgi php-fpm 方式启动的，那么配置完三个步骤我只是重启了apache， php-fpm 是不是也要重启？

sudo service php7.3-fpm restart

OK!! 成功了。

  1. Mysql 链接不上

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

@see https://stackoverflow.com/questions/39281594/error-1698-28000-access-denied-for-user-rootlocalhost

  1. php -r 'phpinfo();' | grep 'mysql'

pecl安装php扩展

Pecl全称The PHP Extension Community Library，php社区扩展库，由社区编写，维护。

使用pecl方便之处在于我们不用到处找源码包下载编译，配置，不用手动phpize,configure,make,make install,自动识别模块安装路径，

我们只需要编辑php.ini配置文件开启扩展，当然我们也需要自己配置一些参数的时候可以先下载源码再构建

Composer

  1. php composer.phar update 时候warning: Failed to download phpunit/phpunit-mock-objects from dist: The zip extension and unzip command are both missing, skipping.

解决：没有安装zip导致的。 sudo apt-get install zip

  1. 启动
# 1 启动apache2
sudo service apache2 start

# 2 启动php-fpm
sudo service php7.3-fpm start

# 3 启动mysql
sudo service mysql start

MYSQL

# root 用户登录
sudo mysql -u root -p;
# 新建用户
create user 'singcl'@'localhost' indentified by 'singcl';
# 新建数据库
create database project;
# 授权用户singcl@localhost 拥有数据库project 的所有权;
# https://blog.csdn.net/lindiwo/article/details/81708166
grant all privileges on project.* to singcl@localhost identified by 'singcl';
# 刷新
flush privileges;
# 切换用户
mysql -u singcl -p;

# 在 SQL 中新建一个 project 数据库（上面已经完成），增加一个item 表、并插入两条记录，命令如下：
#CREATE DATABASE `project` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
USE `project`;

CREATE TABLE `item` (
    `id` int(11) NOT NULL auto_increment,
    `item_name` varchar(255) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
 
INSERT INTO `item` VALUES(1, 'Hello World.');
INSERT INTO `item` VALUES(2, 'Lets go!');

MAC 使用系统自带的Apache和PHP-FPM 开启Apache+PHP-FPM服务

  1. copy一份配置文件
cd /etc/cd /etc/apache2/
sudo cp httpd.conf.bak httpd.conf
  1. 打开配置文件编辑
sudo vim httpd.conf

解开相关依赖模块注释，如图 需要解注释

  1. 配置web服务器目录

web根目录配置

  1. 解开虚拟主机路径 web根目录配置

  2. 配置vhost

sudo vim extra/httpd-vhosts.conf

如图： web根目录配置

好了，现在配置已经完成。在/data/www下建一个文件：

touch index.php
<?php
  phpinfo();

OK, 访问localhost： web根目录配置

大功告成！

错误

  1. php SQLSTATE[HY000] [2002] No such file or directory

解决：将数据库配置里面'localhost'改为127.0.0.1即可。

  1. 要想使.htaccess 重写规则生效的话:
AllowOverride None
# 改为
AllowOverride All
