nginx
使用
brew install nginx
安装nginx
,注意如果卡在brew update
上面的话可以使用ctrl+c
跳过
当然这种方法治标不治本,具体参考 [Linux实践] macOS平台Homebrew更新brew update卡死,完美解决mac查看端口对应的进程
在Linux下,查看占用端口的进程可以使用netstat -antpl | grep port
,但是在Mac下,这个netstat
的功能缩水了(很多命令在Mac下都缩水了),所以怎么查看占用端口的进程呢?
搜索了一遍,感觉可以使用lsof -i tcp:{port}
这个命令来实现,{port}
表示端口号。网址:localhost:8080
Nginx默认index.html文件的位置
在nginx.conf文件中,我们看到根路径是:
root html;
问题是:“html”的相对路径在哪里?此相对路径在编译时设置。您可以通过命令检查路径
$>nginx -V
您将看到“--prefix = / usr / local / Cellar / nginx / 1.12.0_1”
,这是nginx
文件的文件夹。现在你应该“cd”
到这个目录,看看你的“html”
文件夹。
$> cd /usr/local/Cellar/nginx/1.12.0_1
$> ls -l html
然后你会看到“html”文件夹是“/ usr / local / var / www”的软链接
总之,在我的例子中,“html”文件夹是“/ usr / local / var / www”。
php环境的搭建
mac自带php,但是环境配置需要进行一些添加
1. nginx php-fpm file not found错误
server {
listen [::]:80;
server_name example.com www.example.com;
access_log /var/www/logs/example.com.access.log;
location / {
root /var/www/example.com;
index index.html index.htm index.pl;
}
location /images {
autoindex on;
}
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/example.com$fastcgi_script_name;
include fastcgi_params;
}
}
这个配置中有很多不合理的地方,其中一个明显的问题就是root
指令被放到了location /
块。如果root
指令被定义在location
块中那么该root
指令只能对其所在的location
生效。其它location
中没有root
指令,像 location /images
块不会匹配任何请求,需要在每个请求中重复配置root指令来解决这个问题。因此我们需要把root指令放在server块,这样各个 location就会继承父server块定义的$document_root
,如果某个location需要定义一个不同 的$document_root
,则可以在location
单独定义一个root
指令。
另一个问题就是fastCGI
参数SCRIPT_FILENAME
是写死的。如果修改了root
指令的值或者移动文件到别的目录,php-fpm
会返回“No input file specified”
错误,因为SCRIPT_FILENAME
在配置中是写死的并没有随着$doucument_root
变化而变化,我们可以修改 SCRIPT_FILENAME
配置如下:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
所以我们不能忘记在server
块中配置root
指令,不然$document_root
的值为空,只会传$fastcgi_script_name
到php-fpm
,这样就会导致“No input file specified”
错误。
2. 服务器nginx配置问题the page you are looking for is currently unavailable
这个可能出现的问题原因之一是服务器里面有个叫 php-fpm 被停止了。
首先用
ps -ef|grep 9000
监听端口,如果发现 php-fpm被停止了,给启动一下就可以了。
去到对应的php/sbin目录下面执行:./php-fpm
其他常见的对应端口:
ngnx启动对应80端口
php-fpm 对应9000
mysql 对应 3306
3. php-fpm启动报错 failed to open error_log (/usr/var/log/php-fpm.log): No such file or directory
在php-fpm.conf文件下面的[global]
把注释去掉,并且改为
[global]
error_log = /usr/local/var/log/php-fpm.log
或者不修改配置文件中配置项的路径,在php-fpm的运行参数中(-p)指定放置运行时文件的相对路径前缀
$ php-fpm --fpm-config /private/etc/php-fpm.conf --prefix /usr/local/var
到此,php-fpm守护进程已经基本可以正确的启动了。
当然如果没有该文件,可以执行
cp /private/etc/php-fpm.conf.default /private/etc/php-fpm.conf
参考https://github.com/musicode/test/issues/5
Mac 自带
php-fpm
,在终端执行 php-fpm,会报如下错误:
ERROR: failed to open configuration file '/private/etc/php-fpm.conf': No such file or directory (2)
ERROR: failed to load configuration file '/private/etc/php-fpm.conf'
ERROR: FPM initialization failed
错误信息显示,不能打开配置文件,cd /private/etc,发现没有 php-fpm.conf 文件,但是有 php-fpm.conf.default 文件。这个文件是默认配置,我们可以复制一份,改名为 php-fpm.conf,然后再根据需要改动配置。
cp /private/etc/php-fpm.conf.default /private/etc/php-fpm.conf
执行 php-fpm,再次报错:
ERROR: failed to open error_log (/usr/var/log/php-fpm.log): No such file or directory (2)
ERROR: failed to post process the configuration
ERROR: FPM initialization failed
错误信息显示,不能打开错误日志文件。cd /usr/var/log 发现根本没有这个目录,甚至连 var 目录都没有,加上为了避免权限问题,干脆配置到 /usr/local/var/log 目录。
修改 php-fpm.conf error_log 配置为 /usr/local/var/log/php-fpm.log,并把 user 和 group 改为和当前用户一样。
执行 php-fpm,再次报错:
NOTICE: [pool www] 'user' directive is ignored when FPM is not running as root
NOTICE: [pool www] 'group' directive is ignored when FPM is not running as root
于是 sudo php-fpm,再次报错:
ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (48)
ERROR: FPM initialization failed
编辑 php-fpm.conf,修改 listen 为 127.0.0.1:9999。
执行 php-fpm -t,这个世界终于清净了!
mysql
brew install [email protected]
[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have [email protected] first in your PATH run:
echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> /Users/misaki/.bash_profile
For compilers to find [email protected] you may need to set:
export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
For pkg-config to find [email protected] you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig"
To have launchd start [email protected] now and restart at login:
brew services start [email protected]
Or, if you don't want/need a background service you can just run:
/usr/local/opt/[email protected]/bin/mysql.server start
==> Summary
/usr/local/Cellar/[email protected]/5.7.31: 319 files, 235.8MB
mysql安装的时候安装成默认版本后来remove重安装报错:ERROR! The server quit without updating PID file
找了很多百度,都无效,结果还是这篇文章救命了 MySQL 5.7 installed via brew now getting ERROR! The server quit without updating PID file (/usr/local/var/mysql/dev_box.local.pid)
翻译一下
I had mysql version 8 earlier, due to some dependency i had to downgrade to 5.7 so installed [email protected] via brew.
# 我本来安装了mysql8.0版本,但是由于某些原因我需要对mysql降级,降级步骤如下
brew uninstall mysql
brew install [email protected]
mysql.server start
brew link [email protected] --force
Now once i have stopped the server and now i want to restart it but i am getting
# 但现在我遇到了bug
ERROR! The server quit without updating PID file (/usr/local/var/mysql/dev_box.local.pid).
I had the same situation. What helped me is:
# 我遇到类似状况,下面是我的处理方式
First uninstall mysql using brew
# 首先使用brew卸载mysql
brew uninstall mysql
brew uninstall [email protected]
Then manually go through all folders in /usr/local/ and delete everything related to mysql.
# 需要手动删除所有/var/local下面个步mysql相关的文件
For example, I had /usr/local/etc/my.cnf and my.cnf.default, so had to run rm -f /usr/local/etc/my*; also /usr/local/mysql-5.7.21-macos10.13-x86_64 and mysql-8.0.16-macos10.14-x86_64, so rm -rf /usr/local/mysql* and so on.
#执行 run rm -f /usr/local/etc/my*
#执行 rm -rf /usr/local/mysql*
After this is done install using brew
# 然后用brew重新安装
brew install [email protected]
brew services start [email protected]
