==================== PHP 7.0 编译安装==================
wget http://cn2.php.net/get/php-7.0.9.tar.bz2/from/this/mirror -- 下载php镜像

检查配置文件成功后出现的界面：成功通过
阿里云ubuntu16.0 可能出现的错误：
configure: error: Cannot find OpenSSL's libraries
解决办法:
find / -name libssl.so -- 输出结果为 /usr/lib/x86_64-linux-gnu/libssl.so
初步判断它可能只会在 /usr/lib/ 下寻找 libssl.so 文件，在这里做一个软连接即可
ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/
重新编译即可
make -- 编译 或者根据你当前正在编译机器cpu核数调参数加速编译，比如我虚拟机是2核 make -j2 就可以同时跑2个job加速编译，编译了差不多15分钟
sudo make install -- 安装
/opt/php-7.0.9/bin/php -i -- 基本配置信息
/opt/php-7.0.9/bin/php -v -- 注意这里是查看的php-cli 的版本
运行php-fpm服务前，需要把相关的配置文件放好：
sudo mv /opt/php-7.0.9/etc/php-fpm.conf.default /opt/php-7.0.9/etc/php-fpm.conf
sudo mv /opt/php-7.0.9/etc/php-fpm.d/www.conf.default /opt/php-7.0.9/etc/php-fpm.d/www.conf
sudo cp ./php.ini-production /opt/php-7.0.9/etc/php.ini
修改fpm监听的端口：
sudo vi /opt/php-7.0.9/etc/php-fpm.d/www.conf
;listen = 127.0.0.1:9000 -- 默认是打开的，在前面加; 注释掉
listen = /var/run/php7.0.9-fpm.sock -- 添加这一行
启动 php-fpm 服务
sudo /opt/php-7.0.9/sbin/php-fpm -- 启动 php-fpm 服务
提示错误信息
2017/03/23 20:07:53 [crit] 18683#0: *1 connect() to unix:/var/run/php7.0.9-fpm.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1,
server: localhost, request: "GET /index.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php7.0.9-fpm.sock:", host: "127.0.0.1"
解决办法，修改 www.conf 文件
sudo vi /opt/php-7.0.9/etc/php-fpm.d/www.conf
修改之前：
user = www-data group = www-data listen.owner = www-data listen.group = www-data ;listen.mode = 0660
修改之后（注意当前用户为 tinywan:tinywan）
user = tinywan group = tinywan listen.owner = tinywan listen.group = tinywan listen.mode = 0660
然后重启php-fpm 服务，显示同样的错误！查看日志文件信息
给tinywan用户组分配权限：
chown tinywan:tinywan /opt/php-7.0.9/etc/php-fpm.d/www.conf
chown tinywan:tinywan /var/run/php7.0.9-fpm.sock
继续重启php-fpm 服务，正常显示
查看php 安装版本，注意：这里查看服务版本（和cli 版本不一样的），这样子就和浏览器查看的一样的了

注意：如果 php-fpm 服务没有开启则会在Nginx 日志报告以下错误信息：
================= 【2】Nginx 1.10.3 编译安装===============

==================== 【4】Phcalcon 3.0 编译安装=========================
小提示：
官方声明：https://github.com/phalcon/cphalcon/issues/12476
To anyone trying to compile Phalcon for php7, you have to use Zephir:(对于任何想要为php7编译Phalcon的人，你必须使用Zephir：)

官方安装链接：https://phalconphp.com/zh/download/linux
git clone --depth=1 "git://github.com/phalcon/cphalcon.git" cd cphalcon/build sudo ./install
卡在这里安装不了，有莫有啊！O(∩_∩)O哈哈~！！！！！！！！Pass
第二种、官方的博客参考安装(通过扩展方式安装)还失败告终！！！！
官方建议：https://forum.phalconphp.com/discussion/2797/install-halts-on-ubuntu-14-04
cd cphalcon/ext export CFLAGS="-O2 -finline-functions -fvisibility=hidden" phpize ./configure --enable-phalcon make sudo make install
安装后提示的错误信息，于是乎？安装不了了？O(∩_∩)O哈哈~

第三种、通过zephir（php7 推荐也是只有这种方式可以）
如何安装zephir，看这里：http://blog.csdn.net/u011142688/article/details/51619811
这也是官方作者方恨的一句话：https://github.com/phalcon/cphalcon/issues/12476
进入刚才git下来的源码包：
tinywan@tinywan:~$ cd /usr/local tinywan@tinywan:/usr/local$ git clone --depth=1 "git://github.com/phalcon/cphalcon.git" tinywan@tinywan:/usr/local/cphalcon$ cd build/ tinywan@tinywan:/usr/local/cphalcon/build$ ls gccarch.c gcccpuopt gen-build.php install php5 php7 README.md _resource tinywan@tinywan:/usr/local/cphalcon/build$ cd php7/ tinywan@tinywan:/usr/local/cphalcon/build/php7$ ls 32bits 64bits safe tinywan@tinywan:/usr/local/cphalcon/build/php7$ cd 64bits/ tinywan@tinywan:/usr/local/cphalcon/build/php7/64bits$ ls config.m4 config.w32 phalcon.zep.c phalcon.zep.h php_phalcon.h tinywan@tinywan:/usr/local/cphalcon/build/php7/64bits$ sudo phpize Configuring for: PHP Api Version: 20151012 Zend Module Api No: 20151012 Zend Extension Api No: 320151012 tinywan@tinywan:/usr/local/cphalcon/build/php7/64bits$ ls acinclude.m4 autom4te.cache config.guess config.m4 configure config.w32 ltmain.sh missing phalcon.zep.c php_phalcon.h aclocal.m4 build config.h.in config.sub configure.in install-sh Makefile.global mkinstalldirs phalcon.zep.h run-tests.php
记得安装这个：
sudo apt-get install re2c libpcre3-dev -- 不然会提示一下错误
开始了
在这里时候可能要多等会时间去编译 ，完成输出以下界面
root@iZbp1cvkjh1vlb7ff5tspdZ:/home/www# find / -name phalcon.so -- 查找刚才编译的 phalcon.so 文件 /usr/lib/php/20151012/phalcon.so
修改配置文件：vim /opt/php-7.0.9/etc/php.ini 添加一下内容即可
重启 php-fpm （重启前先kill掉以前的进程哦！！！！！！！）
/opt/php-7.0.9/sbin/php-fpm --
phpinfo()文件输出，安装好了！
=========================【5】Swoole扩展 =================
说明：swoole项目已收录到PHP官方扩展库，除了手工下载编译外，还可以通过PHP官方提供的pecl命令，一键下载安装swoole：
pecl install swoole
安装完毕后一下界面
我们可以看到.so文件安装的路径了
/usr/lib/php/20151012/swoole.so
修改配置web配置文件：sudo vim /opt/php-7.0.9/etc/php.ini
重启nginx和php-fpm 浏览器查看即可：
完成安装
测试服务是否可以启用
官方案例：https://linkeddestiny.gitbooks.io/easy-swoole/content/book/chapter01/echo_server.html
至于出现的错误信息：
ERROR swFactoryProcess_finish (ERROR 1004): send 66 byte failed, because session#134 is closed.
自己去看官方github 提问解决：https://github.com/swoole/swoole-src/issues/650
======================上面的都忘记了给cli模式安装扩展模式了
安装：sudo apt install php7.0-cli
tinywan@tinywan:~$ php -v
PHP 7.0.15-0ubuntu0.16.04.4 (cli) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
with Zend OPcache v7.0.15-0ubuntu0.16.04.4, Copyright (c) 1999-2017, by Zend Technologies
同样的找到cli 模式的配置文件
sudo vim /etc/php/7.0/cli/php.ini
注意：在命令行模式没有安装phalcon 扩展
可以看出已经安装成功了！( 参数 --ri 显示扩展 的配置信息 )
命令行模式安装：
curl -s "https://packagecloud.io/install/repositories/phalcon/stable/script.deb.sh" | sudo bash # Ubuntu 16.04+, Debian 9+ sudo apt-get install php7.0-phalcon
====================【6】安装SSH2扩展库让PHP通过SSH连接操作远程服务器
1、编译安装libssh2
wget http://www.libssh2.org/download/libssh2-1.2.9.tar.gz tar zxvf libssh2-1.2.9.tar.gz cd libssh2-1.2.9 ./configure && make && make install
错误解决：Ubuntu 14.04 下安装 Ceph 的错误： no suitable crypto library found
crypto是什么呢? 是OpenSSL 加密库(lib), 这个库需要openssl-devel包 ,在ubuntu中就是 libssl-dev RedHat Fedora 平台 yum -y install openssl-devel Debian ,ubunu 平台 apt-get install libssl-dev
2、编译安装ssh2
（1）官方地址：http://pecl.php.net/package/ssh2
注意：这里安装的是要支持php7的，所以在这里我们选择下载1.0的版本
（2）以下为具体的安装步骤
-- 下载 wget http://pecl.php.net/get/ssh2-1.0.tgz -- 解压 tar -xvf ssh2-1.0.tgz -- 复制目录到指定位置 sudo cp ssh2-1.0 -R /usr/bin/ -- 进入指定目录 cd /usr/bin/ssh2-1.0/ -- 扩展模块 sudo phpize -- 检查配置文件 sudo ./configure --with-ssh2 -- 编译 sudo make --安装 sudo make install --查看安装情况 cd /usr/lib/php/20151012/ -- 修改配置文件 sudo vim /etc/php/7.0/cli/php.ini -- 添加以下内容 extension=/usr/lib/php/20151012/ssh2.so -- 查看模块是否安装成功 php -m | grep ssh2 ssh2 -- 安装结束
（3）安装成功
修改php.ini配置文件 sudo vim /usr/local/php-7.2.8/etc/php.ini，添加：extension=ssh2.so
（4）可能会出现的错误
【1】phpize 找不到，请使用绝对路径：sudo /usr/local/php-7.2.8/bin/phpize
【2】configure: error: Cannot find php-config. Please use --with-php-config=PATH
解决办法：sudo ./configure --with-ssh2 --with-php-config=/usr/local/php-7.2.8/bin/php-config
【3】安装错误
Installing shared extensions: /usr/local/php-7.2.8/lib/php/extensions/no-debug-non-zts-20160303/ Makefile:88: recipe for target 'install-modules' failed make: *** [install-modules] Error 1
解决办法：
cp /usr/bin/ssh2-1.1.2/modules/ssh2.so /usr/local/php-7.2.8/lib/php/extensions/no-debug-non-zts-20160303/
3、PHP通过SSH连接远程服务器示例代码，php登陆ssh执行命令
<?php
$connection=ssh2_connect('172.16.10.3',22);
ssh2_auth_password($connection,$user,$pass);
$cmd="/data/script/start.sh knowledgelib_fix_2";
ssh2_exec($connection,$cmd);
?>

》》》》Ubuntu 14.04.1 LTS---------------Phalcon 框架的编译
PHP 7.0.22 稳定版
一、安装 php-zephir-parser
sudo apt-get install php7.0-dev gcc make re2c autoconf
提示错误：
解决：
1、php7的存储库的问题，添加php7 ppa
sudo add-apt-repository ppa:ondrej/php
2、然后更新
sudo apt-get update
3、现在做一个搜索来确认php7是有的
sudo apt search php7
4、现在安装php7包
sudo apt install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi php7.0 libapache2-mod-php7.0
二、安装Phalcon 扩展
1、克隆下来
git clone https://github.com/phalcon/cphalcon.git
2、按照以下说明为您的平台生成二进制扩展名：
git clone git://github.com/phalcon/cphalcon.git cd cphalcon/build sudo ./install
3、配置php.ini
www@ubuntu1:~$ sudo find / -name phalcon.so [sudo] password for www: /usr/lib/php/20151012/phalcon.so /usr/local/cphalcon/build/php7/64bits/modules/phalcon.so /usr/local/cphalcon/build/php7/64bits/.libs/phalcon.so
