PHP7 學習筆記（一）Ubuntu 16.04 編譯安裝Nginx-1.10.三、 PHP7.0.九、Redis3.0 擴展、Phalcon3.1 擴展、Swoole1.9.8 擴展、ssh2擴展（

 ==================== PHP 7.0 編譯安裝==================

wget http://cn2.php.net/get/php-7.0.9.tar.bz2/from/this/mirror -- 下載php鏡像
tar xvf mirror　　-- 解壓鏡像
cd php-7.0.9/ -- 進入安裝目錄
sudo apt-get update -- 更新阿里雲庫

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爆出缺什麼的錯誤，就在上面命令中加一條 lib<缺的東西名字>-dev(el)

./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

 檢查配置文件成功後出現的界面：成功經過

 阿里雲ubuntu16.0 可能出現的錯誤：

configure: error: Cannot find OpenSSL's libraries

解決辦法:

find / -name libssl.so   -- 輸出結果爲 /usr/lib/x86_64-linux-gnu/libssl.so

初步判斷它可能只會在 /usr/lib/ 下尋找 libssl.so 文件，在這裏作一個軟鏈接便可

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

從新編譯便可

make -- 編譯 或者根據你當前正在編譯機器cpu核數調參數加速編譯，好比我虛擬機是2核 make -j2 就能夠同時跑2個job加速編譯，編譯了差很少15分鐘

sudo make install  -- 安裝

/opt/php-7.0.9/bin/php -i      -- 基本配置信息 

/opt/php-7.0.9/bin/php -v  　　-- 注意這裏是查看的php-cli 的版本

運行php-fpm服務前，須要把相關的配置文件放好：

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監聽的端口：

sudo vi /opt/php-7.0.9/etc/php-fpm.d/www.conf 
;listen = 127.0.0.1:9000 　　-- 默認是打開的，在前面加; 註釋掉
listen = /var/run/php7.0.9-fpm.sock  -- 添加這一行

啓動 php-fpm 服務

sudo /opt/php-7.0.9/sbin/php-fpm  -- 啓動 php-fpm 服務

提示錯誤信息

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"

解決辦法，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

修改以後（注意當前用戶爲 tinywan:tinywan）

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

而後重啓php-fpm 服務，顯示一樣的錯誤！查看日誌文件信息

給tinywan用戶組分配權限：

chown tinywan:tinywan /opt/php-7.0.9/etc/php-fpm.d/www.conf

chown tinywan:tinywan /var/run/php7.0.9-fpm.sock

繼續重啓php-fpm 服務，正常顯示

查看php 安裝版本，注意：這裏查看服務版本（和cli 版本不同的），這樣子就和瀏覽器查看的同樣的了

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

瀏覽器查看：

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 服務沒有開啓則會在Nginx 日誌報告如下錯誤信息：

 

 ================= 【2】Nginx 1.10.3 編譯安裝===============

 下載、解壓

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

 Nginx 配置文件檢測

./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

錯誤提示！！！：

./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.

解決方法：

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 

修改後的代碼：

　　　　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;
        }

重啓Nginx和php-fpm

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

安裝完畢，測試

http://127.0.0.1/index.php -- 在瀏覽器查看

 》》》》CLI添加php的環境變量,將php編譯生成的bin目錄添加到當前Linux系統的環境變量中

 

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

 

 

===================== 【3】Redis 3.0 編譯安裝==================

sudo git clone -b php7 https://github.com/phpredis/phpredis.git -- 下載 記得移動到 mv phpredis /usr/local/ 文件夾下面

 

 sudo apt install php7.0-dev  -- 不安裝則會提示下面錯誤信息

sudo phpize  -- phpize是用來擴展php擴展模塊的，經過phpize能夠創建php的外掛模塊

cd phpredis/  -- 不進入該目錄則會提示下面錯誤信息

sudo ./configure

sudo make 

 安裝：

^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   -- 添加擴展文件 extension=/usr/local/phpredis/modules/redis.so

 

注意要點：若是是PHP7.1以上安裝擴展會出現如下問題，下載編譯的拓展和你的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]

以上問題的解決辦法，從新編譯安裝 並加上  --with-php-config

生成依賴文件

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

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

配置時要將php-config的路徑附上加上  --with-php-config

www@iZ5qqeZ:~/tinywan/phpredis$ ./configure --with-php-config=/usr/local/php-7.1.8/bin/php-config //配置時要將php-config的路徑附上加上

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

~/tinywan/phpredis$ make -j2   // 編譯

www@iZbp14hmrbm6jyw9sa5qqeZ:~/tinywan/phpredis$ sudo make install  //安裝
Installing shared extensions: /usr/local/php-7.1.8/lib/php/extensions/no-debug-non-zts-20160303/  //生成的擴展文件在這裏

修改配置文件：sudo vim /usr/local/php-7.1.8/etc/php.ini 添加擴展文件路徑

配置信息查看

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

sudo killall -9 php-fpm   -- 經過程序的名字，直接殺死全部進程 ，如：php-fpm

 

sudo /opt/php-7.0.9/sbin/php-fpm　　-- 重啓 php-fpm 服務

 cat /usr/local/nginx/html/index.php   -- 寫個redis 測試文件

瀏覽器測試效果圖

Redis 安裝完畢！

 

==================== 【4】Phcalcon 3.0 編譯安裝=========================

小提示：

官方聲明：https://github.com/phalcon/cphalcon/issues/12476

To anyone trying to compile Phalcon for php7, you have to use Zephir:(對於任何想要爲php7編譯Phalcon的人，你必須使用Zephir：)

第一種、官方的方式安裝(按照這種方式PHP7根本安裝不了)失敗了結！！！！

官方安裝連接：https://phalconphp.com/zh/download/linux

git clone --depth=1 "git://github.com/phalcon/cphalcon.git"
cd cphalcon/build
sudo ./install

 

卡在這裏安裝不了，有莫有啊！O(∩_∩)O哈哈~！！！！！！！！Pass

第二種、官方的博客參考安裝(經過擴展方式安裝)還失敗了結！！！！

官方建議：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

安裝後提示的錯誤信息，因而乎？安裝不了了？O(∩_∩)O哈哈~

第三種、經過zephir（php7 推薦也是隻有這種方式能夠）

如何安裝zephir，看這裏：http://blog.csdn.net/u011142688/article/details/51619811

這也是官方做者方恨的一句話：https://github.com/phalcon/cphalcon/issues/12476

進入剛纔git下來的源碼包：

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

 

記得安裝這個：

sudo apt-get install re2c libpcre3-dev   -- 否則會提示一下錯誤

開始了

 在這裏時候可能要多等會時間去編譯 ，完成輸出如下界面

 

root@iZbp1cvkjh1vlb7ff5tspdZ:/home/www# find / -name phalcon.so   -- 查找剛纔編譯的 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  添加一下內容便可

重啓  php-fpm  （重啓前先kill掉之前的進程哦！！！！！！！）

/opt/php-7.0.9/sbin/php-fpm   --

 phpinfo()文件輸出，安裝好了！

 =========================【5】Swoole擴展 =================

說明：swoole項目已收錄到PHP官方擴展庫，除了手工下載編譯外，還能夠經過PHP官方提供的pecl命令，一鍵下載安裝swoole：

pecl install swoole

安裝完畢後一下界面

咱們能夠看到.so文件安裝的路徑了

/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

重啓nginx和php-fpm 瀏覽器查看便可：

完成安裝

測試服務是否能夠啓用

官方案例：https://linkeddestiny.gitbooks.io/easy-swoole/content/book/chapter01/echo_server.html

至於出現的錯誤信息：

ERROR swFactoryProcess_finish (ERROR 1004): send 66 byte failed, because session#134 is closed.

本身去看官方github 提問解決：https://github.com/swoole/swoole-src/issues/650

======================上面的都忘記了給cli模式安裝擴展模式了

安裝：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

一樣的找到cli 模式的配置文件

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

注意：在命令行模式沒有安裝phalcon 擴展

能夠看出已經安裝成功了！( 參數 --ri 顯示擴展 的配置信息 )

命令行模式安裝：

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】安裝SSH2擴展庫讓PHP經過SSH鏈接操做遠程服務器

一、編譯安裝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

錯誤解決：Ubuntu 14.04 下安裝 Ceph 的錯誤： no suitable crypto library found

crypto是什麼呢? 是OpenSSL 加密庫(lib), 這個庫須要openssl-devel包 ,在ubuntu中就是 libssl-dev RedHat Fedora 平臺 yum -y install openssl-devel Debian ,ubunu 平臺 apt-get install libssl-dev

二、編譯安裝ssh2

（1）官方地址：http://pecl.php.net/package/ssh2

注意：這裏安裝的是要支持php7的，因此在這裏咱們選擇下載1.0的版本

（2）如下爲具體的安裝步驟

-- 下載
wget http://pecl.php.net/get/ssh2-1.0.tgz -- 解壓
tar -xvf ssh2-1.0.tgz -- 複製目錄到指定位置
sudo cp ssh2-1.0 -R /usr/bin/

-- 進入指定目錄
cd /usr/bin/ssh2-1.0/

-- 擴展模塊
sudo phpize -- 檢查配置文件
sudo ./configure --with-ssh2

-- 編譯
sudo make --安裝
sudo make install --查看安裝狀況
cd /usr/lib/php/20151012/

-- 修改配置文件
sudo vim /etc/php/7.0/cli/php.ini -- 添加如下內容
extension=/usr/lib/php/20151012/ssh2.so -- 查看模塊是否安裝成功
php -m | grep ssh2 ssh2 -- 安裝結束

（3）安裝成功

 

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）可能會出現的錯誤

【1】phpize 找不到，請使用絕對路徑：sudo /usr/local/php-7.2.8/bin/phpize

【2】configure: error: Cannot find php-config. Please use --with-php-config=PATH

　　解決辦法：sudo ./configure --with-ssh2 --with-php-config=/usr/local/php-7.2.8/bin/php-config

【3】安裝錯誤

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 

 解決辦法：

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經過SSH鏈接遠程服務器示例代碼，php登錄ssh執行命令

<?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、遠程內存顯示案例

 

 composer 和php7.0遇到的一些坑 》》》》》》》》》》

 

剛開始覺得是編譯安裝的PHP7.0的問題，結果不是，是ThingPHP5.0 中的一些擴展不支持PHP7.0

 Phalcon 框架的第四種編譯方式（官方）

》》》》Ubuntu 14.04.1 LTS---------------Phalcon 框架的編譯

PHP 7.0.22 穩定版

1、安裝 php-zephir-parser

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

提示錯誤：

解決：

一、php7的存儲庫的問題，添加php7 ppa

sudo add-apt-repository ppa:ondrej/php

二、而後更新

sudo apt-get update

三、如今作一個搜索來確認php7是有的

sudo apt search php7

四、如今安裝php7包

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

2、安裝Phalcon 擴展

 一、克隆下來

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

二、按照如下說明爲您的平臺生成二進制擴展名：

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
