1. First, update the yum source, otherwise it must be an old version, usually 5.6 and below, but php7 It has been out for a long time, and the performance has improved by more than 50%!

Update the yum source according to the system. Mine is centos7, so I run the following code!

CentOS/RHEL 7.x:

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

If it is centos6, then execute the following code:

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

Then you can directly Yum has installed php7.0. The extensions that can be installed are as follows:

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

With just this command, you can install the following extensions!

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

systemctl 提供了一组子命令来管理单个的 unit，其命令格式为：
systemctl [command] [unit]
command 主要有：
start：立刻启动后面接的 unit。
stop：立刻关闭后面接的 unit。
restart：立刻关闭后启动后面接的 unit，亦即执行 stop 再 start 的意思。
reload：不关闭 unit 的情况下，重新载入配置文件，让设置生效。
enable：设置下次开机时，后面接的 unit 会被启动。
disable：设置下次开机时，后面接的 unit 不会被启动。
status：目前后面接的这个 unit 的状态，会列出有没有正在执行、开机时是否启动等信息。
is-active：目前有没有正在运行中。
is-enable：开机时有没有默认要启用这个 unit。
kill ：不要被 kill 这个名字吓着了，它其实是向运行 unit 的进程发送信号。
show：列出 unit 的配置。
mask：注销 unit，注销后你就无法启动这个 unit 了。
unmask：取消对 unit 的注销。

For example, start php-fpm and start it automatically:

systemctl  start php-fpm
systemctl enable php-fpm
systemctl reload php-fpm   #更改php.ini里面的内容之后平滑重载
