1.php-ini优化

//打开php的安全模式,控制php执行危险函数, 默认是Off,改为On
sql.safe_mode = Off
//关闭php头部信息, 隐藏版本号, 默认是On,该为Off
expose_php = On
//错误信息输出控制
display_error = Off
error_reporting = E_WARNING & E_ERROR
//记录错误日志至后台, 方便追溯
log_errors = On
error_log = /var/log/php_error.log
//每个脚本时间最大内存
memory_limit = 128M
//上传文件最大许可,默认2M, 建议调整为16,32M
upload_max_filesize = 2M
//禁止远程执行phpshell,默认On, 建议Off
allow_url_fopen = On
//时区调整,默认PRC, 建议调整为Asia/Shanghai
date.timezone = PRC


//整体优化后配置文件
sql.safe_mode = Off
expose_php = Off
display_error = Off
error_reporting = E_WARNING & E_ERROR
log_errors = On
error_log = /var/log/php_error.log
upload_max_filesize = 50M
allow_url_fopen = Off
date.timezone = Asia/Shanghai

2.php-fpm优化

PHP-FPM配置文件 4核16G、8核16G

[root@nginx ~]# cat /etc/php-fpm.d/www.conf
[global]
pid = /var/run/php-fpm.pid
#php-fpm程序错误日志
error_log = /var/log/php/php-fpm.log
log_level = warning
rlimit_files = 655350
events.mechanism = epoll

[www]
user = nginx
group = nginx
listen = 127.0.0.1:9000
listen.owner = www
listen.group = www
listen.mode = 0660
 
listen.allowed_clients = 127.0.0.1
pm = dynamic
pm.max_children = 512
pm.start_servers = 10
pm.min_spare_servers = 10
pm.max_spare_servers = 30
pm.process_idle_timeout = 15s;
 
pm.max_requests = 2048

#php-www模块错误日志
php_flag[display_errors] = off
php_admin_value[error_log] = /var/log/php/php-www.log
php_admin_flag[log_errors] = on

#php慢查询日志
request_slowlog_timeout = 5s
slowlog = /var/log/php/php-slow.log

PHP-FPM配置详解释

[global]
#pid设置, 记录程序启动后pid
pid = /var/run/php-fpm.pid
#php-fpm程序启动错误日志路径
error_log = /soft/log/php/php-fpm_error.log
# 错误级别. 可用级别为: alert（必须立即处理）,error（错误情况）, warning（警告情况）, notice（一般重要信息）, debug（调试信息）. 默认: notice.
log_level = warning
#设置文件打开描述符的rlimit限制.
rlimit_files = 65535
events.mechanism = epoll

#启动进程的用户和组
[www]
user = www
group = www

# fpm监听端口
listen = 127.0.0.1:9000
# unix socket设置选项，如果使用tcp方式访问，这里注释即可。
listen.owner = www
listen.group = www
# 允许访问FastCGI进程的IP，any不限制
listen.allowed_clients = 127.0.0.1

# pm设置动态调度
pm = dynamic
# 同一时刻最大的php-fpm子进程数量
pm.max_children = 200
# 动态方式下的起始php-fpm进程数量
pm.start_servers = 20
# 动态方式下服务器空闲时最小php-fpm进程数量
pm.min_spare_servers = 10
# 动态方式下服务器空闲时最大php-fpm进程数量
pm.max_spare_servers = 30
# 最大请求
pm.max_requests = 1024
pm.process_idle_timeout = 15s;

# FPM状态页面,用于监控php-fpm状态使用
pm.status_path = /status
# 错误日志
php_flag[display_errors] = off
php_admin_value[error_log] = /soft/log/php/php-www_error.log
php_admin_flag[log_errors] = on

# 配置php慢查询, 以及慢查询记录日志位置
request_slowlog_timeout = 5s
slowlog = /soft/log/php/php-slow.log
