Ubuntu 14 PHP 5.6 升级到PHP 7.0

备份之前的配置，备份之前的配置，备份之前的配置 ！！！

适用于Ubuntu 14 版本的VPS，Ubuntu 16 版本貌似直接就包含了php7.0

1.先解决有可能存在的语言问题

执行

sudo apt-get update 

sudo apt-get install -y language-pack-en-base

然后命令行配置：

locale-gen en_US.UTF-8

export LANG=en_US.UTF-8

export LC_ALL=en_US.UTF-8

2.删除原来的php5.6

sudo apt-get purge php5-fpm && apt-get --purge autoremove

3.添加php7.0的仓库

 sudo apt-get install software-properties-common

 sudo add-apt-repository ppa:ondrej/php

4.安装php7.0

sudo apt-get update 

sudo apt-get install php7.0

sudo apt-get install php7.0-mysql

sudo apt-get install php7.0-fpm


sudo apt-get install php7.0-curl php7.0-xml php7.0-mcrypt php7.0-json php7.0-gd php7.0-mbstring

上面可以一步一步来安装，如果出现依赖冲突的情况，请一个一个安装。

5.配置新的php.ini

sudo vim /etc/php/7.0/fpm/php.ini

#将cgi.fix_pathinfo=1这一行去掉注释，将1改为0。

6.配置php-fpm

sudo vim /etc/php/7.0/fpm/pool.d/www.conf

#  配置这个 listen = /var/run/php7.0-fpm.sock

7.nginx 配置

sudo vim /etc/nginx/sites-enabled/default

配置相对应的路径和 location,(以laravel项目为例)：

 listen 80 default_server;

 listen [::]:80 default_server ipv6only=on;


root your_website_root;

index index.php index.html index.htm;


# Make site accessible from http://localhost/

server_name your_domain;


location / {

# First attempt to serve request as file, then

# as directory, then fall back to displaying a 404.

try_files $uri $uri/ /index.php?$query_string;

# Uncomment to enable naxsi on this location

# include /etc/nginx/naxsi.rules

}

location ~ \.php$ {

try_files $uri /index.php =404;

fastcgi_split_path_info ^(.+\.php)(/.+)$;

fastcgi_pass unix:/var/run/php7.0-fpm.sock;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

注意这里的 fastcgi_pass unix:/var/run/php7.0-fpm.sock; 要和第6步的 php-fpm 配置：/var/run/php7.0-fpm.sock; 一致。

如果使用 https 的话，推荐：

 ssl on;

 ssl_certificate /etc/nginx/ssl/ssl.crt;

 ssl_certificate_key /etc/nginx/ssl/ssl.key;


ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;

ssl_prefer_server_ciphers on;

开启 gzip 可参考，配置文件位于 nginx.conf：

gzip on;

gzip_disable "msie6";


gzip_vary on;

gzip_proxied any;

gzip_comp_level 5;

gzip_min_length 256;

gzip_buffers 16 8k;

gzip_http_version 1.1;

gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;
