开始编译

make -j4 #指定同时运行的作业数量,让尽可能多的作业同时运行。如果有一个以上的“-j”选项,最后一个选项是有效的。

安装php

make install

添加php.ini配置文件

cp php.ini-production /usr/local/php/lib/php.ini

以下操作为配置php

添加用户

useradd www

修改php-fpm.conf

cd /usr/local/php/etc

cp php-fpm.conf.default php-fpm.conf

cd php-fpm.d

cp www.conf.default www.conf

编辑www.conf文件,根据自己的服务器配置修改以下配置

pm.max_children=10

pm.start_servers=5

pm.min_spare_servers=4

pm.max_spare_servers=7

移除前面的注释;

;env[HOSTNAME] = $HOSTNAME

;env[PATH] = /usr/local/bin:/usr/bin:/bin

;env[TMP] = /tmp

;env[TMPDIR] = /tmp

;env[TEMP] = /tmp

修改php配置文件

cd /usr/local/php/lib

vim php.ini

修改内存限制

memory_limit=512M

修改上传文件限制

post_max_size=512M

upload_max_filesize=512M

启用OPcache 和 JIT; OPcache [1] 通过将 PHP 脚本预编译的字节码存储到共享内存中来提升 PHP 的性能, 存储预编译字节码的好处就是 省去了每次加载和解析 PHP 脚本的开销。

移除注释

;zend_extension=opcache

[opcache]

opcache.enable=1

opcache.memory_consumption=128

;opcache.interned_strings_buffer=8

;opcache.max_accelerated_files=10000

;opcache.validate_timestamps=1

在[opcache]添加jit支持

opcache.jit_buffer_size=128M

注意:虚拟机里可能启动时报错。

ExecStart=/usr/local/php/sbin/php-fpm –nodaemonize –fpm-config /usr/local/php/etc/php-fpm.conf

ExecReload=/bin/kill -USR2 $MAINPID

PrivateTmp=true

WantedBy=multi-user.target

保存退出后执行
