1.安装php：

yum 安装必备

yum install libxml2 libxml2-devel openssl openssl-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel gmp gmp-devel libmcrypt libmcrypt-devel readline readline-devel libxslt libxslt-devel
yum install ntp vim-enhanced gcc gcc-c++ gcc-g77 flex bison autoconf automake glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel libtool* zlib-devel libxml2-devel libjpeg-devel libpng-devel libtiff-devel fontconfig-devel freetype-devel libXpm-devel gettext-devel curl curl-devel pam-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers gzip make bzip2bzip2-devel pcre-devel wget ncurses-devel cmake make perl

yum -y install gcc automake autoconf libtool make gcc-c++ glibc libmcrypt-devel mhash-devel libxslt-devel libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel lib
上面的yum安装存在重复，不去细细排查了，您复制上面三个安装即可

wget -O php7.tar.gz http://cn2.php.net/get/php-7.1.1.tar.gz/from/this/mirror
解压

tar -xvf php7.tar.gz
cd php-7.1.1
编译：

./configure \
--prefix=/usr/local/php \
--with-config-file-path=/etc \
--enable-fpm \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--enable-inline-optimization \

--enable-wddx \
--with-libxml-dir \
--with-xsl \
--enable-zip \
--enable-mysqlnd-compression-support \
--with-pear \
--enable-opcache
在centos7下面，会报错：Don’t know how to define struct flock on this system, set –enable-opcache=no

解决办法：vim /etc/ld.so.conf.d/local.conf # 编辑库文件
/usr/local/lib # 添加该行
:wq # 保存退出
ldconfig # 执行这个命令行，使之生效
！！记得编译完后不能移除这行，会导致php无法启动！！

make && make install
复制配置文件到/etc

cp php.ini-development /etc/php.ini
创建快捷方式：

ln -s /usr/local/php/bin/php /usr/bin/php
配置php-fpm：

cp php.ini-production /etc/php.ini
cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf
cp /usr/local/php/etc/php-fpm.d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf
cp sapi/fpm/init.d.php-fpm /etc/init.d/php-fpm
chmod +x /etc/init.d/php-fpm
启动：

/etc/init.d/php-fpm start
2.安装扩展：

oauth
imap
mongodb
redis （Yii2 不安装redis扩展也是可以用的，可以不用安装）

2.1安装oauth扩展：

wget http://pecl.php.net/get/oauth-2.0.2.tgz
tar -zxf oauth-2.0.2.tgz
cd oauth-2.0.2
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
vim /etc/php.ini # 添加 extension=oauth.so
/etc/init.d/php-fpm restart
2.2 安装imap 扩展

cd php-7.1.1/ext/imap
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-imap=/usr/lib64 --with-imap-ssl --with-kerberos
make && make install
vim /etc/php.ini
extension=imap.so
如果报错：Cannot find imap library (libc-client.a)

yum install libc-client-devel.x86_64
ln -s /usr/lib64/libc-client.so /usr/lib/libc-client.so

2.3 安装 mongodb

wget https://pecl.php.net/get/mongodb-1.2.5.tgz
tar zxvf mongodb-1.2.5.tgz
cd mongodb-1.2.5
/usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config
make && make install
vim /etc/php.ini
extension=mongodb.so

1. 配置

3.1 mysql的配置，要使用127.0.0.1 不要使用localhost

localhost 会使用unix socket，而不是tcp连接。

4.到这里基本就都配置好了。
