這里選擇直接apt-get安裝，因為比起自己編譯簡單多了，不需要自己配置什么

#sudo apt-get install curl libcurl3 libcurl3-dev php5-curl

安裝后重啟nginx

#nginx -s reload

豈知出現(xiàn)錯誤，php全部不能訪問，查看錯誤日志如下：

2014/07/24 23:59:46 [crit] 40455#0: *229072 connect() to unix:/var/run/php5-fpm.sock failed (13: Permission denied) while connecting to upstream, client: 171.9

處理方式是：編輯/etc/php5/fpm/pool.d/www.conf文件，將以下的注釋去掉:

listen.owner = www-data listen.group = www-data listen.mode = 0660

然后重啟php5-fpm

sudo service php5-fpm restart

即可。參考文章：

?

After doing an upgrade on my Debian virtual server, which upgraded PHP and Nginx, I got a "502 Bad Gateway" error when browsing websites on that server. This post shows how to fix this problem, and the configuration option to prevent it occurring again on reboot.?

tl;dr

Edit /etc/php5/fpm/pool.d/www.conf and uncomment the following:
? ? listen.owner = www-data
? ? listen.group = www-data
? ? listen.mode = 0660

Then run:
? ? sudo service php5-fpm restart

Longer answer

As well as the error in the browser, I was getting this error in the Nginx error log:?

[crit] 2686#0: *1 connect() to unix:/var/run/php5-fpm.sock failed (13: Permission denied) while connecting to upstream, client: 192.168.50.1, server: [...], request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "[...]"

The problem is caused by the permissions and ownership of the /var/run/php5-fpm.sock file, which after I'd done the upgrade change to something like root:root and 0660, so it couldn't be accessed by the www-data user which Nginx was running as.

The immediate solution is to change the permissions and/or ownership of the file like so:

chmod 0666 /var/run/php5-fpm.sock

OR

chmod 0660 /var/run/php5-fpm.sock chown www-data:www-data /var/run/php5-fpm.sock

The only catch is this won't persist after the server is restarted. To prevent the issue from occurring again, edit the?/etc/php5/fpm/pool.d/www.conf file:

sudo nano /etc/php5/fpm/pool.d/www.conf

Locate the following lines and uncomment them:

listen.owner = www-data listen.group = www-data listen.mode = 0660

If you already changed the ownership/permissions of the socket file as shown above, then you don't need to do anything else now. If you didn't, then run this:?

sudo service php5-fpm restart

This re-creates the socket file with the ownership and permissions as configured in the file.
