Centos7环境下更新PHP7.2到PHP7.4（WordPress）

升级时需要重新安装扩展，此处仅列出memcache及memcached

【步骤】

1. 备份
服务器快照Snapshot
PHP配置

yum clean all
yum list installed | grep php > /tmp/current-php.txt
cp /etc/php.ini /tmp/php.ini.bak
cp /etc/php-fpm.d/www.conf /tmp/www.conf

 

[可选]
注释掉/etc/php.ini中的extension
;extension=memcached
;extension=memcache
新增/etc/php.d/memcached.ini
; Enable memcached extension module
extension=memcached
新增/etc/php.d/memcache.ini
; Enable memcache extension module
extension=memcache

2. 配置源

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm

yum install yum-utils

yum-config-manager --disable 'remi-php*'
yum-config-manager --enable remi-php74

yum repolist

 

3. 执行Update更新PHP7.4

yum update --nogpgcheck

 

 

4. 检查成果

php -v

 

5. 安装php扩展memcached（选择版本http://pecl.php.net/package，参考https://www.cnblogs.com/flywind/p/6021568.html）

cd /usr/loca/src
wget http://pecl.php.net/get/memcached-3.1.5.tgz
tar zxvf memcached-3.1.5.tgz

cd memcached-3.1.5
/usr/bin/phpize --with-php-config=/usr/bin/php-config

 

# 前提：必须要有libevent库，rpm -qa|grep libevent查看是否安装，版本号2.0以上
# 和libmemcached库(也可直接scp) 参考https://www.cnblogs.com/yhq-qhh/p/9992506.html

./configure --with-php-config=/usr/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached --disable-memcached-sasl
make && make install

 

6. 安装php扩展memcache（选择版本http://pecl.php.net/package，参考https://www.cnblogs.com/yangxia-test/p/4195222.html）

cd /usr/loca/src
wget http://pecl.php.net/get/memcache-8.0.tgz
tar zxvf memcache-8.0.tgz
cd memcache-8.0
/usr/bin/phpize --with-php-config=/usr/bin/php-config
./configure --enable-memcache --with-php-config=/usr/bin/php-config --with-zlib-dir
make && make install

 

7. 重启/自启服务

systemctl restart php-fpm
systemctl restart nginx
systemctl restart memcached
systemctl enable php-fpm

 

9. 检查phpinfo

 

【可能遇到的问题】

1. -bash: yum-config-manager: command not found
执行

yum -y install yum-utils

然后重试

2. memcached make: *** No targets specified and no makefile found. Stop.
检查是否已安装有libevent库，libmemcached库
