PHP7已经到7.0.6版本了,是时候来尝试下小象飞的时候了,哈哈,那么就来配个PHP7的环境来玩玩…

更换时区

$ sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
$ ntpdate time.windows.com && hwclock -w

查看CentOS 版本

$ cat /etc/redhat-release
顺便看看linux环境内核、gcc信息
$ cat /proc/version

更换163 yum 源

  • 登录mirrors.163.com
  • 点击centos后面的“centos使用帮助”
  • $ mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
  • 下载对应版本repo文件, 放入/etc/yum.repos.d/(操作前请做好相应备份),我的是CentOS6

$ cd /etc/yum.repos.d/&&wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
$ yum clean all
$ yum makecache

升级gcc版本

  • 先升级到4.7版本

  • 加入opcache
1
$ sudo vim /usr/local/php7/etc/conf.d/opcache.ini

加入: zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20151012/opcache.so

; Determines if Zend OPCache is enabled 启用opcache
opcache.enable=1
; Determines if Zend OPCache is enabled for the CLI version of PHP 在cli下启用opcache
opcache.enable_cli=1
; The OPcache shared memory storage size. opcache使用的内存,单位MB
opcache.memory_consumption=256
; The amount of memory for interned strings in Mbytes.
opcache.interned_strings_buffer=8
; The maximum number of keys (scripts) in the OPcache hash table.
; Only numbers between 200 and 100000 are allowed. 存储最大的对象数目
opcache.max_accelerated_files=100000
; The maximum percentage of "wasted" memory until a restart is scheduled. 最大浪费内存百分比,超出将会GC
opcache.max_wasted_percentage=5
; When this directive is enabled, the OPcache appends the current working
; directory to the script key, thus eliminating possible collisions between
; files with the same name (basename). Disabling the directive improves
; performance, but may break existing applications.
opcache.use_cwd=1
; When disabled, you must reset the OPcache manually or restart the
; webserver for changes to the filesystem to take effect. 验证文件改动时间错,开启之后将由validate_timestamps来提供刷新频率,对于加载文件很多的程序性能有极大影响,关闭之后将会杜绝验证文件的时候造成的抖动,但是更新文件之后需要手动重启服务或者刷新全部内容
opcache.validate_timestamps=0
; How often (in seconds) to check file timestamps for changes to the shared
; memory storage allocation. ("1" means validate once per second, but only
; once per request. "0" means always validate) 验证时间间隔,1表示1秒,0表示总是验证
opcache.revalidate_freq=5
; Enables or disables file search in include_path optimization
opcache.revalidate_path=1
; If disabled, all PHPDoc comments are dropped from the code to reduce the
; size of the optimized code. 缓存中保存文档信息
opcache.save_comments=1
; If disabled, PHPDoc comments are not loaded from SHM, so "Doc Comments"
; may be always stored (save_comments=1), but not loaded by applications
; that don't need them anyway. 加载文档信息
opcache.load_comments=1
  • 启动
1
$ sudo /etc/init.d/php7-fpm start
  • ==为了安全最好是去掉头信息 X-Powered-By: PHP/7.则修改 php.ini 文件 设置 expose_php = Off==
1
$ vim /usr/local/php7/etc/php.ini

找到 expose_php = On
改为 expose_php = Off
