### 目的 使用新版本PHP，提高代碼執行效率 ### 和線下環境的不同 數據庫采用RDS服務，本地不需要安裝MYSQL 使用緩存服務，需要安裝官方的memcached擴展 ### 需要安裝的擴展 memcached,yar,memcached,apc,mycrypt ### 安裝 ### 升級php ~~~ [root@iZ28vpjayxiZ ~]# yum remove php php-bcmath php-cli php-common php-devel php-fpm php-gd php-imap php-ldap php-mbstring php-mcrypt php-mysql php-odbc php-pdo php-pear php-pecl-igbinary php-xml php-xmlrpc ~~~ ~~~ [root@iZ28vpjayxiZ ~]# rpm -Uvh http://mirror.webtatic.com/yum/el6/latest.rpm ~~~ ~~~ [root@iZ28vpjayxiZ ~]# yum install php55w php55w-bcmath php55w-cli php55w-common php55w-devel php55w-fpm php55w-gd php55w-imap php55w-ldap php55w-mbstring php55w-mcrypt php55w-mysql php55w-odbc php55w-pdo php55w-pear php55w-pecl-igbinary php55w-xml php55w-xmlrpc php55w-opcache php55w-intl php55w-pecl-memcache ~~~ ~~~ [root@iZ28vpjayxiZ ~]# service httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ] ~~~ ### 安裝擴展 ### MemcacheSASL ~~~ [root@iZ28vpjayxiZ html]# yum install gcc+ gcc-c++ Loaded plugins: security Setting up Install Process No package gcc+ available.
