使用brew在macos下安装php开发所需环境 - 温柔的夜

索引

1 软件选择：
2 安装nginx
3 安装php
4 安装mysql

软件选择：

1. php 7.2；
2. mysql 8.0.19；
3. nginx 1.17.8；

所有操作都是基于brew进行的，没有brew的请先读

在macos下安装homebrew

安装nginx

打开终端，输入命令
```
brew install nginx
```

最终输出信息，这是安装成功了

==> nginx
Docroot is: /usr/local/var/www  //nginx主目录存放

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.  //默认端口8080，没有sudo权限也可以用

nginx will load all files in /usr/local/etc/nginx/servers/.  //nginx服务存放

To have launchd start nginx now and restart at login:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  nginx
yumangdembp:~ yumang-root$

根据提示，打开localhost:8080，查看默认页，welcome to nginx
nginx的配置文件存放于/usr/local/etc/nginx
扩展（nginx命令）：
- 启动nginx
```
sudo nginx
```
- 停止nginx
```
sudo nginx - s stop
```
- 重启nginx
```
sudo nginx -s reload
```

安装php

非常简单（接下来会有各种报错，不过都很容易解决）
```
brew install php72
```

php-fpm第一次报错

Last login: Sun Feb 23 06:15:50 on ttys000
yumangdembp:~ yumang-root$ php-fpm
[23-Feb-2020 06:19:28] ERROR: failed to open configuration file '/private/etc/php-fpm.conf': No such file or directory (2)
[23-Feb-2020 06:19:28] ERROR: failed to load configuration file '/private/etc/php-fpm.conf'
[23-Feb-2020 06:19:28] ERROR: FPM initialization failed
yumangdembp:~ yumang-root$

翻译报错信息：打开配置文件/private/etc/php-fpm.conf失败，原因是：No such file or directory（没有这个路径或文件）

那到底是没有路径还是没有文件呢
```
cd /private/etc
```
用cd命令到/private/etc里面看一下，没有php-fpm.conf文件，却有一个php-fpm.conf.default文件

这不难办，直接同目录复制一个就好
```
sudo cp /private/etc/php-fpm.conf.default /private/etc/php-fpm.conf
```
再复制一个做备份
```
sudo cp /private/etc/php-fpm.conf.default /private/etc/php-fpm.conf.bak
```
再次运行php-fpm，第二次报错
```
[23-Feb-2020 06:27:44] ERROR: failed to open error_log (/usr/var/log/php-fpm.log): No such file or directory (2)
[23-Feb-2020 06:27:44] ERROR: failed to post process the configuration
[23-Feb-2020 06:27:44] ERROR: FPM initialization failed
yumangdembp:~ yumang-root$
```
这次问题和刚才的一样，都是没有路径或文件，这次是日志文件。打开/usr/var/log查看php-fpm.log是否存在的时候，你会发现usr下连var目录都没有，别说再下级的log中的php-fpm.log了。
php-fpm.log，/usr/local/var/log里有这个文件，不需要再默认的路径建文件夹拷过去。就用atom修改php-fpm.conf:line:24(搜索error_log)
将
```
; error_log = log/php-fpm.log
```
改为
```
error_log = /usr/local/var/log/php-fpm.log
```

再次运行php-fpm，第三次报错

[23-Feb-2020 06:41:44] WARNING: Nothing matches the include pattern '/private/etc/php-fpm.d/*.conf' from /private/etc/php-fpm.conf at line 125.
[23-Feb-2020 06:41:44] ERROR: No pool defined. at least one pool section must be specified in config file
[23-Feb-2020 06:41:44] ERROR: failed to post process the configuration
[23-Feb-2020 06:41:44] ERROR: FPM initialization failed

line:125是

include=/private/etc/php-fpm.d/*.conf

打开/private/etc/php-fpm.d/ 发现没有conf结尾的文件，复制这个重命名把.default删掉

再次运行php-fpm，第四次报错

[23-Feb-2020 06:52:12] NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root
[23-Feb-2020 06:52:12] NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root
Starting php-fpm 
[23-Feb-2020 06:52:12] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (48)
Starting php-fpm 
[23-Feb-2020 06:52:12] ERROR: FPM initialization failed

前两行是权限不足，直接忽略即可，问题是9000端口的异常占用。

修改/private/etc/php-fpm.d/www.conf:36

listen = 127.0.0.1:9000

改为

listen = 127.0.0.1:9999

修改/usr/local/etc/nginx/nginx.conf:67

#    fastcgi_pass   127.0.0.1:9000;

改为

#    fastcgi_pass   127.0.0.1:9999;

把nginx和php的监听端口都改成9999之后运行php-fpm会有两行notice还是提示权限的问题，不要管他。

yumangdembp:etc yumang-root$ /usr/local/Cellar/php@7.2/7.2.28/sbin/php-fpm -t
[23-Feb-2020 07:03:31] NOTICE: configuration file /usr/local/etc/php/7.2/php-fpm.conf test is successful

yumangdembp:etc yumang-root$

安装mysql

brew install mysql

brew install mysql  //安装，一般一分钟内即可下载完成
mysql.server start  //启动mysql服务

mysql_secure_installation //初始化配置

New password: //输入密码

Re-enter new password: //确认

Estimated strength of the password: 100 //密码强度(大写，小写，数字，符号，大于八位，我用的Wrdy0408.就满分密码了)
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y //确定用这个密码吗？（Y）
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y //删除匿名用户(Y)
Success.

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : n //开启远程登录(N)

... skipping.
By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y //删除自带的test库(Y)
- Dropping test database...
Success.

- Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y //重载privilege tables（Y）
Success.

All done!

yumangdembp:~ yumang-root$ mysql -u root -p
