安装libzip1.x版本
在php7.3版本中，要求libzip版本要大于等于0.11，否则配置出错

[root@blogs src]# yum remove -y libzip.x86_64 libzip-devel.x86_64
[root@blogs src]# wget https://libzip.org/download/libzip-1.2.0.tar.gz
[root@blogs src]# tar xf libzip-1.2.0.tar.gz

优化php配置
php-fpm.conf

[root@blogs /]# grep -Ev ";|^$" /usr/local/php/etc/php-fpm.conf
[global]
pid = run/php-fpm.pid #pid文件位置
error_log = log/php-fpm.log #日志路径
log_level = notice #日志级别 {alert, error, warning, notice, debug}

www.conf

[root@blogs /]# grep -Ev ";|^\(" /usr/local/php/etc/php-fpm.d/www.conf [www] user = php group = php listen = 127.0.0.1:9000 pm = dynamic pm.max_children = 20 pm.start_servers = 5 pm.min_spare_servers = 5 pm.max_spare_servers = 20 pm.max_requests = 2000 slowlog = log/\)pool.log.slow
rlimit_files = 65536
参赛解释：
pm = dynamic
php-fpm分为两种模式，静态和动态，当pm = static是为静态模式,pm = dynamic时为动态模式。
php-fpm可以根据所处于的模式对进程数量进行减少或增加，在静态模式下，无法增加或减少进程，在动态模式下可以根据配置的参数进行自动调整进程数量，在繁忙的时候可以多打开几个进程数，在请求少时使用较少的进程数量，从而合理的使用资源。

pm.max_children
静态方式下开启的php-fpm进程数量，此参数指定了php-fpm的进程数量，只有在 pm = static的状态下生效

pm.start_servers
动态方式下的起始php-fpm进程数量，在pm = dynamic下，刚开始启动的php-fpm进程数量，只有在 pm = dynamic的状态下生效

pm.min_spare_servers
动态方式下的最小php-fpm进程数量，随机调整到最小的php-fpm进程数量，只有在 pm = dynamic的状态下生效

pm.max_spare_servers
动态方式下的最大php-fpm进程数量，随机调整到最大的php-fpm进程数量，只有在 pm = dynamic的状态下生效
注：pm.max_spare_servers指定的进程数量必须等于或小于pm.max_children进程数量，否则启动失败

pm.max_requests
设置每个子进程重生之前服务的请求数。对于可能存在内存泄漏的第三方模块来说是非常有用的。如果设置为 ‘0’ 则一直接受请求，等同于 PHP_FCGI_MAX_REQUESTS 环境变量。默认值：0

rlimit_files
php-fpm进程的文件打开数，此数量需要php-fpm运行用户php具备这个打开数

启动php-fpm
可以看到php-fpm的进程数量与我们配置文件中设定的一致
