Ond?ej Sury 的 PHP PPA 為 Ubuntu 16.04/14.04 提供了 PHP7.2 版本，軟件源安裝的 PHP 默認以 Unix Socket 的狀態運行在 /run/php/php7.2-fpm.sock，比使用 TCP 以 localhost:9000 的方式性能更好。

1、安裝軟件源拓展工具：

apt -y install software-properties-common apt-transport-https lsb-release ca-certificates

2、添加PHP PPA 源 并更新緩存

add-apt-repository ppa:ondrej/php & apt update

3、安裝php7.2及基礎相關拓展

apt install php7.2-fpm php7.2-mysql php7.2-curl php7.2-gd php7.2-mbstring php7.2-xml php7.2-xmlrpc php7.2-zip php7.2-opcache php7.2-dev -y

5、選擇安裝 redis igbinary pear擴展

php7后每個擴展都是一個獨立的ini文件 本次安裝的php擴展都在/etc/php/7.2/mods-available下

apt install php-redis php-igbinary php-pear
ls /etc/php/7.2/mods-available
calendar.ini fileinfo.ini igbinary.ini opcache.ini readline.ini
sysvmsg.ini xml.ini zip.ini ctype.ini ftp.ini
json.ini pdo.ini redis.ini
sysvsem.ini xmlreader.ini
curl.ini gd.ini mbstring.ini pdo_mysql.ini shmop.ini
sysvshm.ini xmlrpc.ini
dom.ini gettext.ini mysqli.ini phar.ini simplexml.ini
tokenizer.ini xmlwriter.ini
exif.ini iconv.ini mysqlnd.ini posix.ini sockets.ini
wddx.ini xsl.ini

6、安裝nghttp2庫

apt install nghttp2 libnghttp2-dev

7、安裝redis官方異步拓展hiredis，如報錯需要增加系統gcc支持

git clone https://github.com/redis/hire…
cd hiredis
make -j
如果報錯 嘗試安裝gcc
apt install gcc
重新編譯
make -j
make install
ldconfig

8、swoole拓展編譯安裝，不推薦使用pecl install swoole

pecl的安裝方式沒有編譯http2與hiredis支持 gcc-4.4 或更高版本 make autoconf pcre (centos系統可以執行命令：yum install pcre-devel)

git clone https://gitee.com/swoole/swoo…
cd swoole
phpize
./configure –enable-http2 –enable-async-redis
make && make install

9、添加swoole擴展到php環境中

echo 'extension=swoole.so' >> /etc/php/7.2/mods-available/swoole.ini
cd /etc/php/7.2/cli/conf.d/ && ln -s ../../mods-available/swoole.ini 20-swoole.ini
cd /etc/php/7.2/fpm/conf.d/ && ln -s ../../mods-available/swoole.ini 20-swoole.ini

10、查看是否引用成功

php –ri swoole
swoole support => enabled
Version => 2.1.2-alpha
Author => tianfeng.han[email: mikan.tenny@gmail.com]
coroutine => enabled
epoll => enabled
eventfd => enabled
timerfd => enabled
signalfd => enabled
cpu affinity => enabled
spinlock => enabled
rwlock => enabled
async redis client => enabled
async http/websocket client => enabled
openssl => enabled
http2 => enabled
Linux Native AIO => enabled
pcre => enabled
mutex_timedlock => enabled
pthread_barrier => enabled
futex => enabled

Directive => Local Value => Master Value
swoole.aio_thread_num => 2 => 2
swoole.display_errors => On => On
swoole.use_namespace => On => On
swoole.use_shortname => On => On
swoole.fast_serialize => Off => Off
swoole.unixsock_buffer_size => 8388608 => 8388608

至此完整全部完成
