Centos 7 下的 PHP7/Nginx/Memcached 安装步骤。对的，没有Mysql,有RDS懒得装Mysql了。

一、获取相关开源程序

1、安装环境所需的程序库

sudo -s
LANG=C
yum -y update
yum remove mariadb*
yum -y install patch make cmake gcc gcc-c++ bison flex file libtool libtool-libs autoconf kernel-devel libjpeg libjpeg-devel libpng libpng-devel gd gd-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel libidn libidn-devel gmp-devel gettext gettext-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers vim-minimal nano  gmp-devel unzip libcap diffutils readline-devel libxslt libxslt-devel ntp wget ctags libedit libedit-devel libaio git mailx jwhois bind-utils systemd systemd-devel libtidy libtidy-devel
yum -y install supervisor
yum -y install memcached

2、准备环境变量

echo -e "/lib64\n/usr/lib64\n/usr/local/lib64\n/lib\n/usr/lib\n/usr/local/lib\n`cat /etc/ld.so.conf`" > /etc/ld.so.conf
/sbin/ldconfig

3、下载程序源码包

cd /usr/local/src
wget http://7xk96f.com1.z0.glb.clouddn.com/software/libiconv/libiconv-1.15.tar.gz
wget -O php-7.1.5.tar.gz http://cn2.php.net/get/php-7.1.5.tar.gz/from/this/mirror

tar zxf libiconv-1.15.tar.gz
cd libiconv-1.15/
./configure --prefix=/usr
make && make install
cd ../

tar zxf libmcrypt-2.5.8.tar.gz

cd pcre-8.40/
./configure --prefix=/usr --enable-utf8
make && make install
cd ../

2、安装Nginx

tar zxf nginx-1.13.0.tar.gz
cd nginx-1.13.0/

#using system OpenSSL
yum -y install openssl openssl-devel
./configure --prefix=/usr/local --conf-path=/usr/local/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --lock-path=/run/lock/nginx.lock --pid-path=/run/nginx.pid \
--with-http_ssl_module --with-http_v2_module --with-http_image_filter_module --with-http_xslt_module --with-http_realip_module --with-http_stub_status_module \

--with-threads --with-http_ssl_module --with-http_gzip_static_module --without-mail_imap_module --without-mail_pop3_module --without-mail_smtp_module \
--without-http_uwsgi_module --without-http_scgi_module --without-select_module \
--with-cc-opt='-O2'

#use customize OpenSSL
sed -i "s#/.openssl##g" auto/lib/openssl/conf
./configure --prefix=/usr/local --conf-path=/usr/local/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-log-path=/var/log/nginx/access.log --http-proxy-temp-path=/var/lib/nginx/proxy --lock-path=/run/lock/nginx.lock --pid-path=/run/nginx.pid \
--with-http_ssl_module --with-http_v2_module --with-http_image_filter_module --with-http_xslt_module --with-http_realip_module --with-http_stub_status_module \
--with-pcre-jit --with-http_flv_module --with-http_mp4_module --with-http_addition_module \

--without-http_uwsgi_module --without-http_scgi_module --without-select_module \
--with-openssl=/usr/local/ssl \
--with-cc-opt='-O2'

make && make install
cd ../
mkdir /var/log/nginx
mkdir /var/lib/nginx

四、收尾

1、添加www用户

/usr/sbin/groupadd www
/usr/sbin/useradd -M -g www www

2、优化内核

#for aliyun
cat >>/etc/security/limits.conf<<eof
* soft nproc 65535
* hard nproc 65535
eof

#other
cat >>/etc/security/limits.conf<<eof
* soft nproc 65535
* hard nproc 65535
* soft nofile 65535
* hard nofile 65535
eof

echo "fs.file-max=65535" >> /etc/sysctl.conf

3、设置开机启动

systemctl enable nginx.service
systemctl enable php-fpm.service
systemctl enable memcached.service
systemctl enable supervisord.service
