ubuntu16.04 PHP7安裝與Nginx PHP

nginx PHP常見錯誤

1、php7.0-fpm.sock權限不足：

[crit] 3182#3182: *20 connect() to unix:/run/php/php7.0-fpm.sock failed (13: Permission denied)

2、webroot路徑不對：

[error] 3147#3147: *10 FastCGI sent in stderr: "Unable to open primary script: /etc/nginx/html/index.php (No such file or directory)" while reading response header from upstream

PHP7安裝

刪除PHP7

apt-get autoremove --purge php7.0 php7.0-cli php7.0-common php7.0-fpm php7.0-gd php7.0-json php7.0-mbstring php7.0-mcrypt php7.0-mcrypt php7.0-mysql php7.0-opcache php7.0-readline php7.0-sqlite3

安裝PHP7

apt-get install php7.0 php7.0-cli php7.0-common php7.0-fpm php7.0-gd php7.0-json php7.0-mbstring php7.0-mcrypt php7.0-mcrypt php7.0-mysql php7.0-opcache php7.0-readline php7.0-sqlite3

#修改php .ini

vi /etc/php/7.0/fpm/php.ini

設定cgi.fix_pathinfo = 0

修改www.conf

vi /etc/php/7.0/fpm/pool.d/www.conf

把listen.mode = 0660 改成listen .mode = 0666

php7.0-fpm.sock預設(0660)權限

$ls -al /run/php/php7.0-fpm.sock
srw-rw----  1 www-data www-data   0 Mar 22 13:17 php7.0-fpm.sock

php7.0-fpm.sock(0666)權限

$ls -al /run/php/php7.0-fpm.sock
srw-rw-rw-  1 www-data www-data   0 Mar 22 13:17 php7.0-fpm.sock

重啟系統，這樣/run/php/php7.0-fpm.sock 檔案才會根據0666 權限重新產生

nginx PHP設定

location ~ \.php$ {
        root /your/web/root/document //必填，否则$document_root会是默认值/etc/nginx/html
        fastcgi_pass   unix:/run/php/php7.0-fpm.sock;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

對應的錯誤可以在Nginx的日誌/var/log/nginx/error.log中看到
