PHP7.4也出了一段时间了，也尝试升级过，一直升级错误，今天折腾一下，升级成功了。

系统环境和对应软件版本。
systemos：centos7.7以上
nginx-1.18.0
MariaDB-10.4.12
php-7.4.5

在Centos 8 中部署LNMP环境并安装WordPress
CentOS 7安装 LNMP（Linux+Nginx+MariaDB+PHP）
Centos7 LNMP一键安装脚本

1、安装依赖环境

1.1、安装EPEL源

[root@uscdn1 ~]# yum -y install epel-release.noarch

1.2、firewalld开放http和https端口

[root@uscdn1 ~]# firewall-cmd --zone=public --add-service=http --permanent
[root@uscdn1 ~]# firewall-cmd --zone=public --add-service=https --permanent
[root@uscdn1 ~]# firewall-cmd --reload


1.3、安装相关依赖包：

[root@uscdn1 ~]# yum -y install gcc gcc-c++ make cmake  perl autoconf automake libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel ncurses ncurses-devel curl curl-devel openssl openssl-devel pcre pcre-devel libtool  pcre-devel libaio-devel libaio bzip2-devel libcurl-devel gd-devel bison bison-devel  mhash openldap openldap-devel libicu-devel

[root@uscdn1 php-7.4.5]# ./configure -with-php-config=/usr/local/php/bin/php-config -with-pdo-mysql=mysqlnd
[root@uscdn1 php-7.4.5]# make && make install

5、配置php.ini、php-fpm.conf、www.conf文件

[root@uscdn1 php-7.4.5]# vi /usr/local/php/etc/php.ini

;配置MySQL socket文件
pdo_mysql.default_socket= /var/lib/mysql/mysql.sock
mysqli.default_socket = /var/lib/mysql/mysql.sock

;不显示错误，默认
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），默认
log_errors = On

;字符集，默认
default_charset = "UTF-8"

;文件上传大小，默认值太小，建议修改10M
upload_max_filesize = 2M

;Maximum size of POST data that PHP will accept.  表单最大值，默认是8M，如果表单含有多图上传，大小可能不够。超过该大小后台收不到 表单数据
post_max_size = 8M

;设置PHP的扩展库路径，默认被注释了，之后一个文件夹 于 你/usr/local/php/lib/php/extensions/ 下的文件夹同名。
extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20190902/"
extension = "pdo_mysql.so"
extension = "ldap.so"
extension = "zip.so"

;设置PHP的时区
date.timezone = PRC

;开启opcache，默认是0
[opcache]
; Determines if Zend OPCache is enabled
zend_extension= "/usr/local/php/lib/php/extensions/no-debug-non-zts-20190902/opcache.so"
opcache.enable=1

### 配置/usr/local/php/etc/php-fpm.conf文件

[root@uscdn1 php-7.4.5]# vi /usr/local/php/etc/php-fpm.conf

; 去掉里分号，方便以后重启。建议修改
;Default Value: none
; 下面的值最终目录是/usr/local/php/var/run/php-fpm.pid
; 开启后可以平滑重启php-fpm
pid = run/php-fpm.pid

; 设置错误日志的路径，可以默认值
; Note: the default prefix is /usr/local/php/var
; Default Value: log/php-fpm.log, 即/usr/local/php/var/log/php-fpm.log
error_log = /var/log/php-fpm/error.log

; Log等级，可以默认值
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
log_level = notice

; 后台运行，默认yes，可以默认值
; Default Value: yes
;daemonize = yes

; 引入www.conf文件中的配置，可以默认值
include=/usr/local/php/etc/php-fpm.d/*.conf

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

[root@uscdn1 php-7.4.5]# vi /usr/local/php/etc/php-fpm.d/www.conf
; 设置用户和用户组，默认都是nobody。可以默认值
user = nobody
group = nobody

; 设置PHP监听
; 下面是默认值，不建议使用。可以默认值
listen = 127.0.0.1:9000
; 根据nginx.conf中的配置fastcgi_pass unix:/dev/shm/php-fpm.sock;
listen = /dev/shm/php-fpm.sock

;修改权限
listen.owner = nobody
listen.group = nobody
listen.mode = 0660

######开启慢日志。可以默认值
slowlog = /var/log/php-fpm/$pool-slow.log
request_slowlog_timeout = 10s



### 添加PHP-fpm自启动和启动
[root@uscdn1 ~]# systemctl enable php-fpm.service 
[root@uscdn1 ~]# systemctl start php-fpm.service 

至此，最新版LNMP(PHP-7.4.5 Nginx-1.18.0 MariaDB-10.4.12)安装完成。
