make && make install

复制配置文件

cp php.ini-production /usr/local/php8/etc/php.ini
cp sapi/fpm/php-fpm.service /lib/systemd/system/php-fpm.service
cp /usr/local/php8/etc/php-fpm.conf.default /usr/local/php8/etc/php-fpm.conf
cp /usr/local/php8/etc/php-fpm.d/www.conf.default /usr/local/php8/etc/php-fpm.d/www.conf

配置/usr/local/php8/etc/php-fpm.conf

1
2
3

pid = /run/php-fpm.pid
error_log = /var/log/php/fpm-error.log
include=/usr/local/php8/etc/php-fpm.d/*.conf

配置/usr/local/php8/etc/php-fpm.d/www.conf

###### 设置用户和用户组
user = www
group = www

###### 根据nginx.conf中的配置fastcgi_pass unix:/dev/shm/php-fpm.sock;设置PHP监听
;listen = 127.0.0.1:9000   #####不建议使用
listen = /dev/shm/php-fpm.sock
listen.owner = www
listen.group = www
listen.mode = 0777
listen.allowed_clients = /dev/shm/php-fpm.sock

###### 使用静态进程数max_children=内存/512
pm = static
pm.max_children = 200
pm.max_requests = 0

pm.status_path = /FpmStatus

###### 开启慢日志
slowlog = /var/log/php/fpm-$pool-slow.log
request_slowlog_timeout = 30s
request_slowlog_trace_depth = 20
request_terminate_timeout = 0

配置/usr/local/php8/etc/php.ini

######避免PHP信息暴露在http头中
expose_php = Off

######常用配置
error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
display_errors = Off
log_errors = On
html_errors = Off
error_log = /var/log/php/cli-error.log
ignore_repeated_errors = On
ignore_repeated_source = On

memory_limit = 512M
max_execution_time = 600  (0为不限制)
max_input_time = -1
post_max_size = 128M
max_input_vars = 1000000
file_uploads = On
upload_tmp_dir = /tmp/www
upload_max_filesize = 100M
session.gc_maxlifetime = 14400
default_socket_timeout = 600  (-1为不限制)
###### 设置PHP的扩展
extension_dir = "/usr/local/php8/lib/php/extensions/以安装目录为准"
zend_extension=opcache.so
extension=mcrypt.so
extension=mysqli.so
extension=pdo_mysql.so
extension=redis.so
extension=swoole.so

###### 设置PHP的时区
date.timezone = "Asia/Shanghai"

###### 开启opcache
[opcache]
opcache.enable=1
opcache.enable_cli=1

##### 开启JIT
opcache.jit_buffer_size=128M
opcache.jit=1205
opcache.huge_code_pages=1
opcache.file_cache=/tmp
######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;

----- 使用redis的session才需要配置 ----
session.save_handler = redis
session.save_path = "tcp://*****.aliyuncs.com:6379? 
auth=******"

[MySQLi]
mysqli.reconnect = On

在配置文件中使用到的路径或文件，配置权限

mkdir -p /var/log/php/
mkdir -p /var/log/php-fpm/
mkdir -p /run/php-fpm/
mkdir -p /var/lib/php/session

touch /dev/shm/php-fpm.sock
touch /run/php-fpm.pid
chown www:www /dev/shm/php-fpm.sock
chmod 777 /dev/shm/php-fpm.sock
chown -R www:www /var/lib/php

配置PHP连接MySQL的端口监听文件

1 2	touch /dev/shm/mysql.sock chmod 777 /dev/shm/mysql.sock

测试php-fpm配置，设置开机自启动

测试配置

1	/usr/local/php8/sbin/php-fpm -t

修改文件权限

1	chmod 745 /lib/systemd/system/php-fpm.service

设置为开机启动

1	systemctl enable php-fpm.service

启动php-fpm

1	systemctl start php-fpm.service

加入环境变量

vi /etc/profile  底部加入

export PATH=$PATH:/usr/local/php8/bin
source /etc/profile

安装mysql （等待更新）
