php配置文件有哪些

php  /  管理员 发布于 7年前   128

与nginx搭配使用的php，有三个配置文件：php.ini、php-fpm.conf、www.conf。

php.ini是php运行时的核心配置。CLI形式、php-fpm模式下的PHP进程，都读取php.ini中的配置项。 （推荐学习：PHP视频教程）

php-fpm.conf 是php-fpm管理下的php进程的配置文件。该模式下运行的php进程，除读取php.ini中的配置项外，
还读取php-fpm.conf中的配置项。

www.conf 是 php-fpm.conf 的补充。

php.ini中的重要配置

######避免PHP信息暴露在http头中expose_php = Off######避免暴露php错误信息display_errors = Off######在关闭display_errors后开启PHP错误日志（路径在php-fpm.conf中配置）log_errors = On######设置PHP的扩展库路径extension_dir = "/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/"######设置PHP的opcache和mysql动态库zend_extension=opcache.soextension=mysqli.soextension=pdo_mysql.so######设置PHP的时区date.timezone = PRC######开启opcache[opcache]; Determines if Zend OPCache is enabledopcache.enable=1######设置PHP脚本允许访问的目录（需要根据实际情况配置）;open_basedir = /usr/share/nginx/html;

php-fpm.conf中的重要配置

;php运行日志error_log=log/php-fpm.log;FPM使用的事件机制events.mechanism = epoll;php-fpm.conf的补充文件www.conf的路径include=/usr/cg/lnmp/php-7.0.13/etc/php-fpm.d/*.conf

www.conf的重要配置

;php-fpm运行的linux用户组和用户user = wwwgroup = www;接收FastCGI请求的地址listen = 127.0.0.1:9000; Choose how the process manager will control the number of child processes.; Possible Values:;   static  - a fixed number (pm.max_children) of child processes;;   dynamic - the number of child processes are set dynamically based on the; following directives. With this process management, there will be; always at least 1 children.; pm.max_children      - the maximum number of children that can;be alive at the same time.; pm.start_servers     - the number of children created on startup.; pm.min_spare_servers - the minimum number of children in 'idle';state (waiting to process). If the number;of 'idle' processes is less than this;number then some children will be created.; pm.max_spare_servers - the maximum number of children in 'idle';state (waiting to process). If the number;of 'idle' processes is greater than this;number then some children will be killed.;  ondemand - no children are created at startup. Children will be forked when; new requests will connect. The following parameter are used:; pm.max_children           - the maximum number of children that;     can be alive at the same time.; pm.process_idle_timeout   - The number of seconds after which;     an idle process will be killed.; Note: This value is mandatory.pm = dynamic; The number of child processes to be created when pm is set to 'static' and the; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.; This value sets the limit on the number of simultaneous requests that will be; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP; CGI. The below defaults are based on a server without much resources. Don't; forget to tweak pm.* to fit your needs.; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'; Note: This value is mandatory.pm.max_children = 5; The number of child processes created on startup.; Note: Used only when pm is set to 'dynamic'; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2pm.start_servers = 2; The desired minimum number of idle server processes.; Note: Used only when pm is set to 'dynamic'; Note: Mandatory when pm is set to 'dynamic'pm.min_spare_servers = 1; The desired maximum number of idle server processes.; Note: Used only when pm is set to 'dynamic'; Note: Mandatory when pm is set to 'dynamic'pm.max_spare_servers = 3; The number of seconds after which an idle process will be killed.; Note: Used only when pm is set to 'ondemand'; Default Value: 10s;pm.process_idle_timeout = 10s;;php进程在回收前应该处理的请求;防止第三方库的内存泄漏pm.max_requests = 500;耗时长的php处理日志slowlog = log/$pool.log.slow;php慢日志的时间标准，最小单位是秒，0是未开启慢日志request_slowlog_timeout = 0; 可在php文件中通过getenv('TEMP')获取环境变量的值; Default Value: clean env;env[HOSTNAME] = $HOSTNAME;env[PATH] = /usr/local/bin:/usr/bin:/bin;env[TMP] = /tmp;env[TMPDIR] = /tmpenv[TEMP] = /tmp; 覆盖php.ini中的对应配置;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f [email protected];php_flag[display_errors] = off;php_admin_value[error_log] = /var/log/fpm-php.www.log;php_admin_flag[log_errors] = onphp_admin_value[memory_limit] = 32M
