多版本php

安装nginx

yum list | grep nginx
yum -y install nginx
iptables -F
setenforce 0
systemctl start nginx
#自己编译
## 下载nginx安装包，版本根据自己需求自己替换
wget http://nginx.org/download/nginx-1.10.3.tar.gz

## 解压缩
tar -xvf nginx-1.10.3.tar.gz

## 进入解压后的目录
cd nginx-1.10.3

## 安装nginx所需功能
yum install -y pcre-devel openssl openssl-devel

## 配置信息，--prefix为安装文件的目录
./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_stub_status_module --with-http_auth_request_module --with-threads --with-stream --with-stream_ssl_module --with-http_slice_module --with-mail --with-mail_ssl_module --with-file-aio --with-http_v2_module --with-ipv6 --with-pcre

## 编译和安装
make && make install
## 将nginx加入到systemctl中
vi /usr/lib/systemd/system/nginx.service

## 配置信息
[Unit]
Description=nginx.service
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target
## 更改/etc/profile文件
vim /etc/profile

## 配置信息，在文件末尾加入下面语句，多个环境变量用:隔开
export PATH=$PATH:/usr/local/nginx/sbin
## 每次配置nginx后检查是否配置成功
nginx -t

## 重启nginx
nginx -s reload

## systemctl命令
## 开机启动
systemctl enable *.service
## 取消开机启动
systemctl disable *.service
## 启动
systemctl start *.service
## 停止
systemctl stop *.service
## 1 若 nginx 启动成功，但浏览器无法访问，关闭防火墙，或开启相应端口
## 关闭防火墙
service firewalld stop
firewall-cmd --zone=public --add-port=80/tcp --permanent
#需要重启防火墙生效 很重要
service firewalld restart
# or 
service firewalld stop
service firewalld start

Fast-CGI 模块是 Nginx 的一个模块，用于与 Fast-CGI 程序通信。

一般PHP-FPM进程占用20~30m左右的内存就按30m算

物理内存 / 30M
如果单机不仅仅跑了PHP-FPM，建议留一半给PHP

物理内存 / 2 / 30M
PHP-FPM = PHP FastCGI Process Manager，用于启动并管理 PHP 进程且提供 Fast-CGI 接口，能够和 Nginx 的 Fast-CGI 模块通信。

避免泛解析  总有些人会把域名解析错地址或者是恶意解析到你的服务器上。对于这种人必须严惩
       
       server {
           listen       80  default_server;
           server_name  _;
           return       403;
       }

安装php7

rpm -ivh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
yum list | grep php
yum -y install mod_php70w php70w-cli php70w-fpm php70w-common php70w-devel
systemctl restart nginx
systemctl start php-fpm

安装PHP7.2

//下载php的安装文件
wget http://cn2.php.net/distributions/php-7.2.3.tar.gz
//解压
tar zxvf php-7.2.3.tar.gz
//进入解压后的目录
cd php-7.2.3
//配置安装参数
./configure --enable-fpm --prefix=/usr/local/php
//编译安装
make && make install

找到问题了,大体上是因为内存不足,临时使用交换分区来解决吧

sudo dd if=/dev/zero of=/swapfile bs=64M count=16
sudo mkswap /swapfile
sudo swapon /swapfile

编译完成，可以取消交换分区：

sudo swapoff /swapfile
sudo rm /swapfile

错误 ： configure: error: libxml2 not found. Please check your libxml2 installation
yum install -y libxml2 libxml2-devel

Libraries have been installed in:
   /root/php-7.2.3/ext/pcntl/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

多 Laravel 项目配置

http {
    access_log  /dev/null;
    include mime.types;
    default_type application/octet-stream;

    sendfile on;

    keepalive_timeout 120;

    client_header_buffer_size 256k;
    large_client_header_buffers 4 256k;
    client_max_body_size 200M;
    client_body_buffer_size 512k;

    map $host $dir {
        ~^(.*)$ /Home/user/laravel/$1/public;
    }

    server {
        listen 80;
        listen 443 ssl http2;
        ssl_certificate /home/ssl.crt;
        ssl_certificate_key /home/ssl.key;

        server_name  _;
        root $dir;

        location / {
            index index.html index.htm index.php;
            try_files $uri $uri/ /index.php?$query_string;
        }

        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
            fastcgi_param  QUERY_STRING       $query_string;
            include        fastcgi_params;
        }

        location = /debug {
            default_type text/plain;
            return 200 $dir;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}
在 /etc/hosts 中, 添加如下

127.0.0.1 a.site.com
127.0.0.1 b.site.com
然后

/Home/user/laravel/a.site.com/ 部署 a.site.com 的项目
/Home/user/laravel/b.site.com/ 部署 b.site.com 的项目
重点在那个 map 指令上. 具体用法大家自己看文档去吧

安装openssl

cd /usr/local/src/php/extension/openssl
运行phpize命令
运行 ./configure --with-php-config=/usr/local/php/bin/php-config命令
运行make & make install
如果报错pcntl.lo' is not a valid libtool object或者其他类似not a valid libtool object的错误
运行make clean
make install执行成功之后会产生一个.so文件，记住这个文件的位置

phpize可能会出现以下错误

Cannot find config.m4. 
Make sure that you run '/opt/local/bin/phpize' in the top level source directory of the module
将config0.m4改名为config.m4或者直接·cp config0.m4 config.m4就可以解决
在php.ini配置文件中添加以下内容
#我的.so文件统一放在/usr/local/lib/php/extension目录下
extension_dir="/usr/local/lib/php/extension"
extension=openssl.so

找到php-fpm master进程 https://learnku.com/articles/24557
ps aux | grep php-fpm

pid是2367
重启这个进程
 kill -USR2 2367 
INT, TERM 立刻终止
QUIT 平滑终止
USR1 重新打开日志文件
USR2 平滑重载所有worker进程并重新载入配置和二进制模块

升级 PHP7

利用 PHPCS和PHPCompatibility 对项目进行PHP7的编码规范检测。

//PHPCS和PHPCompatibility安装和使用流程
mkdir /tmp/php_codesniffer 
curl -s http://getcomposer.org/installer | php 
./composer.phar config -g repo.packagist composer https://packagist.phpcomposer.com 
./composer.phar selfupdate 
./composer.phar require "squizlabs/php_codesniffer=*" 
cd /tmp/PHPCompatibility 
git clone https://github.com/wimg/PHPCompatibility.git 
/tmp/PHPCompatibility/vendor/bin/phpcs --config-set installed_paths /tmp/PHPCompatibility/PHPCompatibility/ 
/tmp/PHPCompatibility/vendor/bin/phpcs -i 
/tmp/PHPCompatibility/vendor/bin/phpcs --standard=PHPCompatibility --report-file=/tmp/check_php7_report [项目路径] 
之后就可以根据生成的报表'/tmp/check_php7_report'，逐条对项目代码进行处理了。
调用过的接口使用脚本分别在PHP5.6和PHP7的环境下重新调用获取返回值，把两次的返回值md5加密后进行对比

有了方案后处理起来并不难，按照预期应该是一致的，但是确实存在问题了
php7的json_encode处理float类型会出现溢出的现象

php5.6:[6.28] 
>>> json_encode(6.28)
=> "6.28"
php7:[6.2800000000000002] 
>>> json_encode(6.28)
=> "6.2800000000000002"
解决方案：修改php.ini中serialize_precision 到17以下，自测php7恢复正常
