MacBook 重装 Apache 和 PHP 7.2

时间 2019-11-18

标签 macbook 重装 apache php 7.2 栏目 MacBook 繁體版

原文原文链接

20190718 原本是要作一个 php 的验证码，结果发如今个人 macbook 上死活不出图片，可是在windows 上是能够的！判定问题出在环境上！

macOS Mojave 10.14.5 
WEB： 自带的 apache
PHP：自带的 php 7.1

通过一大圈折腾，最终的结果是：重装了 apache，重装了 php7.2，缘由在于苹果10.14以后，内置的 apache，再也不加载那些第三方组件库！

原文以下php

Detected macOS Mojave 10.14. There are serious issues with it, due to the original apache not loading
foreign libraries anymore. PHP within apache will most certainly not work anymore if you proceed!
The cli version still will.
See this issue at https://github.com/liip/php-osx/issues/249 for details and discussion
...

一、百度找资料

https://github.com/liip/php-osx/issues/249 上这里找办法！ 这里再抄写一次最终的解决步骤html

macOS comes with pre-installed apache, following are the commands to stop it and prevent from autostart on boot: $ sudo apachectl stop $ sudo launchctl unload /System/Library/LaunchDaemons/org.apache.httpd.plist 2>/dev/nulllinux
Install apache through homebrew $ brew install httpdgit
Check apache installation through the following command and the output should be /usr/local/bin/apachectl $ which apachectlgithub
Start apache through the following command $ sudo apachectl -k startweb
Set apache to startup on bootload $ sudo brew services start httpdapache
Re-install php from https://php-osx.liip.ch link.bootstrap

二、个人错误

我是在先 brew install php 7.2 以后，才看到的以上网址，因此，以上 step 6 我来回浪费了一些时间！由于我在 step 6 最后都是失败的！ https://php-osx.liip.ch/ 这里列举了各个 php 版本的重装 php 方式，我尝试了 7.2 和 7.1vim

$ curl -s https://php-osx.liip.ch/install.sh | bash -s 7.2windows

Restart this script with
 curl -s https://php-osx.liip.ch/install.sh | bash -s force 7.2
to really install it

$ curl -s https://php-osx.liip.ch/install.sh | bash -s force 7.2 通过漫长的下载、等待以后错误以下：

当时没有抄录下来，大概记得是
did or could not .....

只好冷静下来，一步一步的设置！ 想回头，回头的繁琐和继续前行的难度，工做量都不小！（抱歉！我没有使用 TM 的习惯！）

三、设置 apache

新的 apache 在哪里？ $ which apachectl
```
/usr/local/bin/apachectl
```
以前记录过，旧的 apache 在
```
/usr/sbin/httpd
```
测试一下打开浏览器，输入 127.0.0.1:8080 It works!

配置文件在哪里安装的时候没有注意，一时晕乎！后来在 ps 命令下看到了

$ ps -ef |grep httpd

   501   660   394   0  6:03下午 ttys000    0:00.00 grep httpd

$ cd /usr/local/opt/ $ ls -l

  lrwxr-xr-t  1 dhbm  admin  22  7 18 17:05 httpd -> ../Cellar/httpd/2.4.34

apache2 和 apache-httpd 找了，都不是！只有找这个 httpd

$ cd /usr/local/etc/httpd/ $ ls -l

total 200
-rw-r--r--   1 dhbm  admin      0  7 18 21:09 Caveats

drwxr-xr-x   4 dhbm  admin    128  7 18 17:05 original

看文件清淡和建立时间，应该这就是新的 apache 配置的地方了！

$ vim httpd.conf Listen 8080 改为 Listen 80

sudo apachectl -k restart 再次测试 127.0.0.1，仍是能够显示 It works! 查找 DocumentRoot，看到了如今的 root 位置！

DocumentRoot "/usr/local/var/www"
<Directory "/usr/local/var/www">

cd /usr/local/var/www 创建一个 info.php，而后

http://127.0.0.1/info.php 结果原文显示了！说明 php 支持没有安装！

$ cat info.php <?php phpinfo(); ?>

三、安装 php 7.2

$ brew search php **记录很重要，必定先保存下来，后续问题须要查看

 To enable PHP in Apache add the following to httpd.conf and restart Apache:
     LoadModule php7_module /usr/local/opt/php/lib/httpd/modules/libphp7.so

     <FilesMatch \.php$>
         SetHandler application/x-httpd-php
     </FilesMatch>

 Finally, check DirectoryIndex includes index.php
     DirectoryIndex index.php index.html

 The php.ini and php-fpm.ini file can be found in:
     /usr/local/etc/php/7.2/

 To have launchd start php now and restart at login:
   brew services start php
 Or, if you don't want/need a background service you can just run:
   php-fpm

看到一些 conflicts 和 it was not symlinked into ...，我心虚了！没有启动新安装的 php！还想回头使用自带的 php 7.1！

** 重要的启动提示信息以下

To have launchd start php now and restart at login:
  brew services start php
Or, if you don't want/need a background service you can just run:
  php-fpm

🍺  /usr/local/Cellar/php/7.2.8: 515 files, 79.1MB

$ sudo vim /usr/local/etc/httpd/httpd.conf 从旧的目录下（ /etc/apache2 ）的 httpd.conf 找到 php 模块，cp 到新的 httpd.conf

$ sudo apachectl restart httpd: Syntax error on line 187 of /usr/local/etc/httpd/httpd.conf: Cannot load libexec/apache2/libphp7.so into server: dlopen(/usr/local/opt/httpd/libexec/apache2/libphp7.so, 10): image not found

*** 找不到 libphp7.so 了！

从新设置 php 7.2 以上保存的 php 安装记录中找到 php 设置部分

终于 ok 了！

四、后续问题

1. 中文目录乱码
2. 系统 php 版本和 web 的 php 版本不同
3. brew link 失败
4. php 验证码不显示图片
