centos 安装pecl
一、更新yum源，安装php7

CentOS/RHEL 7.x:

1 rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

2 rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

CentOS/RHEL 6.x:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm

rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm

yum安装php7.0：（拓展自选）

yum install php70w-common php70w-fpm php70w-opcache php70w-gd php70w-mysqlnd php70w-mbstring php70w-pecl-memcached php70w-devel

以上命令安装了下面的拓展！

php-api, php-bz2, php-calendar, php-ctype, php-curl, php-date, php-exif, php-fileinfo, php-filter, php-ftp, php-gettext, php-gmp, php-hash, php-iconv, php-json, php-libxml, php-openssl, php-pcre, php-pecl-Fileinfo, php-pecl-phar, php-pecl-zip, php-reflection, php-session, php-shmop, php-simplexml, php-sockets, php-spl, php-tokenizer, php-zend-abi, php-zip, php-zlib

二、安装PECL

//php版本 > 7

$ wget http://pear.php.net/go-pear.phar

$ php go-pear.phar



//php版本 < 7

$ yum install php-pear

//否则会报错PHP Parse error: syntax error, unexpected //'new' (T_NEW) in /usr/share/pear/PEAR/Frontend.php on //line 91

三、安装swoole

$ sudo pecl install swoole

//报错如下//Warning: Invalid argument supplied for foreach() in //Command.php on line 249

vi `which pecl`

//找到最后一行

exec $PHP -C -n -q $INCARG -d date.timezone=UTC -d output_buffering=1 -d variables_order=EGPCS -d safe_mode=0 -d register_argc_argv="On" $INCDIR/peclcmd.php "$@"



去掉 -n 标示



//报错如下

//running: phpize

//Can't find PHP headers in /usr/include/php



安装 PHP devel



成功！

//Build process completed successfully

//Installing '/usr/lib64/php/modules/swoole.so'

//install ok: channel://pecl.php.net/swoole-1.9.8

四、配置 php.ini

$ php -i | grep php.ini

//修改或者添加

extension=swoole.so

五、卸载扩展

php.ini 中删除 extension=swoole.so

卸载,切换到PHP安装目录下的bin

./pecl uninstall swoole(已swoole为例)
