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 memcached2、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/ldconfig3、下载程序源码包
cd /usr/local/src

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 www2、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.conf3、设置开机启动
systemctl enable nginx.service
systemctl enable php-fpm.service
systemctl enable memcached.service
systemctl enable supervisord.service
