==================== PHP 7.0 编译安装==================php

wget http://cn2.php.net/get/php-7.0.9.tar.bz2/from/this/mirror -- 下载php镜像
tar xvf mirror　　-- 解压镜像
cd php-7.0.9/ -- 进入安装目录
sudo apt-get update -- 更新阿里云库

sudo apt-get install libkrb5-dev \ 
libc-client2007e                 \ 
libc-client2007e-dev             \ 
libcurl4-openssl-dev             \ 
libbz2-dev                       \ 
libjpeg-dev                      \ 
libmcrypt-dev                    \ 
libxslt1-dev                     \ 
libxslt1.1                       \ 
libpq-dev                        \ 
libpng12-dev                     \ 
libfreetype6-dev                 \ 
build-essential                  \ 
git                              \

若是下面的./configure爆出缺什么的错误，就在上面命令中加一条 lib<缺的东西名字>-dev(el)html

./configure \ --prefix=/opt/php-7.0.9 \ --with-config-file-path=/opt/php-7.0.9/etc \ --with-zlib-dir \ --with-freetype-dir \ --enable-mbstring \ --with-libxml-dir=/usr \ --enable-soap \ --enable-calendar \ --with-curl \ --with-mcrypt \ --with-zlib \ --with-gd \ --disable-rpath \ --enable-inline-optimization \ --with-bz2 \ --with-zlib \ --enable-sockets \ --enable-sysvsem \ --enable-sysvshm \ --enable-pcntl \ --enable-mbregex \ --enable-exif \ --enable-bcmath \ --with-mhash \ --enable-zip \ --with-pcre-regex \ --with-pdo-mysql \ --with-mysqli \ --with-mysql-sock=/var/run/mysqld/mysqld.sock \ --with-jpeg-dir=/usr \ --with-png-dir=/usr \ --enable-gd-native-ttf \ --with-openssl \ --with-fpm-user=www-data \ --with-fpm-group=www-data \ --enable-ftp \ --with-imap \ --with-imap-ssl \ --with-kerberos \ --with-gettext \ --with-xmlrpc \ --with-xsl \ --enable-opcache \ --enable-fpm

检查配置文件成功后出现的界面：成功经过mysql

阿里云ubuntu16.0 可能出现的错误：linux

configure: error: Cannot find OpenSSL's libraries

解决办法:nginx

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，在这里作一个软链接便可git

ln -s /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/

从新编译便可github

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，好比我虚拟机是2核 make -j2 就能够同时跑2个job加速编译，编译了差很少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，须要把相关的配置文件放好：web

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：redis

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sql

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

修改以前：

user = www-data
group = www-data

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

修改以后（注意当前用户为 tinywan:tinywan）

user = tinywan group = tinywan listen.owner = tinywan listen.group = tinywan listen.mode = 0660

而后重启php-fpm 服务，显示一样的错误！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 版本不同的），这样子就和浏览器查看的同样的了

tinywan@tinywan:~$ sudo /opt/php-7.0.9/sbin/php-fpm -v PHP 7.0.9 (fpm-fcgi) (built: Mar 23 2017 19:53:02) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

浏览器查看：

php cli 版本查看

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

配置Nginx 配置文件nginx.conf,

fastcgi_pass unix:/var/run/php7.0.9-fpm.sock;

注意：若是 php-fpm 服务没有开启则会在Nginx 日志报告如下错误信息：

================= 【2】Nginx 1.10.3 编译安装===============

下载、解压

wget http://nginx.org/download/nginx-1.10.3.tar.gz
tar -zxvf nginx-1.10.3.tar.gz

Nginx 配置文件检测

./configure --prefix=/usr/local/nginx --with-debug --with-http_realip_module --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --user=www --group=www

错误提示！！！：

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

解决方法：

apt-get install libreadline-dev libncurses5-dev libpcre3-dev \
libssl-dev perl make build-essential curl

修改配置文件: vi /usr/local/nginx/conf/nginx.conf

修改后的代码：

　　　　location ~ \.php$ {
            fastcgi_pass   unix:/var/run/php7.0.9-fpm.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

重启Nginx和php-fpm

/usr/local/nginx/sbin/nginx -s reload

安装完毕，测试

http://127.0.0.1/index.php -- 在浏览器查看

》》》》CLI添加php的环境变量,将php编译生成的bin目录添加到当前Linux系统的环境变量中

sudo vim /etc/profile 
//添加如下内容： export PATH=$PATH:/usr/local/php-7.1.8/bin //使生效
source /etc/profile

===================== 【3】Redis 3.0 编译安装==================

sudo git clone -b php7 https://github.com/phpredis/phpredis.git -- 下载 记得移动到 mv phpredis /usr/local/ 文件夹下面

 sudo apt install php7.0-dev  -- 不安装则会提示下面错误信息

sudo phpize  -- phpize是用来扩展php扩展模块的，经过phpize能够创建php的外挂模块

cd phpredis/  -- 不进入该目录则会提示下面错误信息

sudo ./configure

sudo make

安装：

^Cwww@i:/usr/local/phpredis$ sudo make install Installing shared extensions: /usr/lib/php/20151012/

生成的redis.so文件

 sudo vim /opt/php-7.0.9/etc/php.ini   -- 添加扩展文件 extension=/usr/local/phpredis/modules/redis.so

注意要点：若是是PHP7.1以上安装扩展会出现如下问题，下载编译的拓展和你的PHP版本不符合

www@iZbqqeZ:~/tinywan/phpredis$ sudo service php-fpm restart Stopping PHP-FPM Server ... [OK] Starting PHP-FPM Server ... [29-Aug-2017 09:55:53] NOTICE: PHP message: PHP Warning: PHP Startup: redis: Unable to initialize module Module compiled with module API=20151012 PHP compiled with module API=20160303 These options need to match in Unknown on line 0 [OK]

以上问题的解决办法，从新编译安装并加上 --with-php-config

生成依赖文件

www@iZbqeZ:~/tinywan/phpredis$ /usr/local/php-7.1.8/bin/phpize //写全phpize的路径

Configuring for: 
PHP Api Version: 20160303 
Zend Module Api No: 20160303 
Zend Extension Api No: 320160303

配置时要将php-config的路径附上加上  --with-php-config

www@iZ5qqeZ:~/tinywan/phpredis$ ./configure --with-php-config=/usr/local/php-7.1.8/bin/php-config //配置时要将php-config的路径附上加上

checking for grep that handles long lines and -e... /bin/grep

~/tinywan/phpredis$ make -j2   // 编译

www@iZbp14hmrbm6jyw9sa5qqeZ:~/tinywan/phpredis$ sudo make install //安装
Installing shared extensions: /usr/local/php-7.1.8/lib/php/extensions/no-debug-non-zts-20160303/ //生成的扩展文件在这里

修改配置文件：sudo vim /usr/local/php-7.1.8/etc/php.ini 添加扩展文件路径

配置信息查看

ps -aux | grep php-fpm   -- 查看php-fpm 进程

sudo killall -9 php-fpm   -- 经过程序的名字，直接杀死全部进程 ，如：php-fpm

sudo /opt/php-7.0.9/sbin/php-fpm　　-- 重启 php-fpm 服务

 cat /usr/local/nginx/html/index.php   -- 写个redis 测试文件

浏览器测试效果图

Redis 安装完毕！

==================== 【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：)

第一种、官方的方式安装(按照这种方式PHP7根本安装不了)失败了结！！！！

官方安装连接：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(经过扩展方式安装)还失败了结！！！！

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，因而乎？安装不了了？O(∩_∩)O哈哈~

第三种、经过zephir（php7 推荐也是只有这种方式能够）

如何安装zephir，看这里：http://blog.csdn.net/u011142688/article/details/51619811

这也是官方做者方恨的一句话：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   -- 否则会提示一下错误

开始了

在这里时候可能要多等会时间去编译，完成输出如下界面

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 添加一下内容便可

重启 php-fpm （重启前先kill掉之前的进程哦！！！！！！！）

/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，还能够经过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

咱们能够看到.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 浏览器查看便可：

完成安装

测试服务是否能够启用

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.

本身去看官方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

一样的找到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

能够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经过SSH链接操做远程服务器

一、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), 这个库须要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

二、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，因此在这里咱们选择下载1.0的版本

（2）如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 --查看安装状况
cd /usr/lib/php/20151012/

-- 修改配置文件
sudo vim /etc/php/7.0/cli/php.ini -- 添加如下内容
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/

三、PHP经过SSH链接远程服务器示例代码，php登录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); ?>

四、远程内存显示案例

composer 和php7.0遇到的一些坑》》》》》》》》》》

刚开始觉得是编译安装的PHP7.0的问题，结果不是，是ThingPHP5.0 中的一些扩展不支持PHP7.0

14.0 ----------------------

问题一：unable to locate package php7.0 and libapache2-mod-php7.0

解决办法：https://wyldeplayground.net/unable-to-locate-package-php7-0libapache2-mod-php7-0/

Phalcon 框架的第四种编译方式（官方）

》》》》Ubuntu 14.04.1 LTS---------------Phalcon 框架的编译

PHP 7.0.22 稳定版

1、安装 php-zephir-parser

sudo apt-get install php7.0-dev gcc make re2c autoconf

提示错误：

解决：

一、php7的存储库的问题，添加php7 ppa

sudo add-apt-repository ppa:ondrej/php

二、而后更新

sudo apt-get update

三、如今作一个搜索来确认php7是有的

sudo apt search php7

四、如今安装php7包

sudo apt install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi  php7.0 libapache2-mod-php7.0

2、安装Phalcon 扩展

一、克隆下来

git clone https://github.com/phalcon/cphalcon.git

二、按照如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

三、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
sudo vim /opt/php7.0.22/etc/php.ini

》》》》 Zephir 写PHP扩展的，编译Phalcon框架的源码为zep 编码的问题与解决

PHP版本：7.0.22

系统：Ubuntu 14.04.1 LTS

出现的错误问题：

解决办法：因为缺乏xml扩展，安装扩展便可：sudo apt-get install php7.0-xml
