centos7下安裝php+memcached簡單記錄

 

1）centos7下安裝php

需要再新增一個yum源來安裝php-fpm，可以使用webtatic（這個yum源對國內網路來說恐怕有些慢，當然你也可以選擇其它的yum源）
[root@nextcloud-server ~]# rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
  
安裝php7-fpm和一些其它的必要的元件
[root@nextcloud-server ~]# yum -y install php70w-fpm php70w-cli php70w-gd php70w-mcrypt php70w-mysql php70w-pear php70w-xml php70w-mbstring php70w-pdo php70w-json php70w-pecl-apcu php70w-pecl-apcu-devel
  
完成後，檢查一下php-fpm是否已正常安裝
[root@nextcloud-server ~]# php -v
PHP 7.0.25 (cli) (built: Oct 29 2017 13:43:03) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
    
配置php-fpm
[root@nextcloud-server ~]# vim /etc/php-fpm.d/www.conf
.....
user = nginx                                   //將使用者和組都改為nginx
group = nginx
.....
listen = 127.0.0.1:9000                        //php-fpm所監聽的埠為9000
......
env[HOSTNAME] = $HOSTNAME                     //去掉下面幾行註釋
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp
    
在/var/lib目錄下為session路徑建立一個新的資料夾，並將使用者名稱和組設為nginx
[root@nextcloud-server ~]# mkdir -p /var/lib/php/session
[root@nextcloud-server ~]# chown nginx:nginx -R /var/lib/php/session/
[root@nextcloud-server ~]# ll -d /var/lib/php/session/
drwxr-xr-x. 2 nginx nginx 4096 1月  25 09:47 /var/lib/php/session/
    
啟動Nginx和php-fpm服務，並新增開機啟動
[root@nextcloud-server ~]# systemctl start php-fpm
[root@nextcloud-server ~]# systemctl enable php-fpm

1）安裝php的memcached擴充套件模組

需要先安裝依賴庫 libmemcached
[root@nextcloud src]# wget https://launchpad.net/libmemcached/1.0/1.0.18/+download/libmemcached-1.0.18.tar.gz
[root@nextcloud src]# tar -zxf libmemcached-1.0.18.tar.gz
[root@nextcloud src]# cd libmemcached-1.0.18/
[root@nextcloud libmemcached-1.0.18]# ./configure && make && make install

安裝好依賴庫之後，我們來安裝 memcached ：
從 github 克隆 memcached 後，需要手動切換到 php7 分支，不然會提示報錯：
fatal error : ext / standard / php_smart_str . h : No such file or directory 錯誤。

[root@nextcloud src]# git clone https://github.com/php-memcached-dev/php-memcached.git
[root@nextcloud src]# cd php-memcached/
[root@nextcloud php-memcached]# git checkout php7
[root@nextcloud php-memcached]# phpize 
[root@nextcloud php-memcached]# ./configure --disable-memcached-sasl --with-libmemcached-die=/usr/local/libmemcached
[root@nextcloud php-memcached]# make && make install

[root@nextcloud ~]# find / -name memcached.so
/usr/lib64/php/modules/memcached.so
/usr/local/src/php-memcached/.libs/memcached.so
/usr/local/src/php-memcached/modules/memcached.so
[root@nextcloud ~]# vim /etc/php.ini
......
extension=/usr/lib64/php/modules/memcached.so

[root@nextcloud ~]# systemctl restart php-fpm
[root@nextcloud ~]# php -m
....
memcached
