1.安装redis扩展
wget https://pecl.php.net/get/redis-5.2.2.tgz
tar xf redis-5.2.2.tgz
cd redis-5.2.2
/usr/local/php7/bin/phpize
./configure --with-php-config=/usr/local/php7/bin/php-config
make && make install

2.安装memcached扩展
2.1安装libmemcached
wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
./configure --prefix=/usr/local/libmemcached
make && make install
2.2安装memcached
wget https://pecl.php.net/get/memcached-3.1.5.tgz
tar xf memcached-3.1.5.tgz
cd memcached-3.1.5
/usr/local/php7/bin/phpize
./configure --enable-memcached --with-php-config=/usr/local/php7/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl
make && make install

3.安装imagick
wget https://pecl.php.net/get/imagick-3.4.4.tgz
tar xf imagick-3.4.4.tgz
cd imagick-3.4.4
/usr/local/php7/bin/phpize
./configure --with-php-config=/usr/local/php7/bin/php-config --with-imagick=/usr/local/imagemagick
make && make install

4.安装zip
1.wget https://libzip.org/download/libzip-1.2.0.tar.gz
tar -zxvf libzip-1.2.0.tar.gz cd libzip-1.2.0 2. ./configure make && make install
装完了之后找一下/usr/local/lib下有没有pkgconfig目录，有的话执行命令export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/"指定PKG_CONFIG_PATH。
到这里问题解决！

5.nginx
wget http://nginx.org/download/nginx-1.18.0.tar.gz
tar -xzvf nginx-1.18.0.tar.gz
cd nginx-1.18.0
保存原来的旧nginx配置文件
cp /etc/nginx/nginx.conf nginx.conf.old
tar cvf nginx.confd.tar /etc/nginx/conf.d

./configure
--prefix=/usr/local/nginx
--sbin-path=/usr/sbin/nginx
--conf-path=/etc/nginx/nginx.conf
--pid-path=/run/nginx.pid
--with-http_ssl_module
