在阿裡雲主機上，操作系統是Centos6，php版本是5.3。因為安裝Yii2.0的需要，我要升級php為5.4。因為還有5.5和5.6，當然要升到高版本了。我決定升到5.6。
首先，按照這裡的步驟 http://zhidao.baidu.com/link?url=8w_-5AhIIWNfbenvClexBpIWD0rA1YHxWsBp89KHiyQjq9A9V5hsbcHjs1awmyOq2dgMVSx-Hpl3IO42Wpqv-JTOF_YH4jscUXDMYIDdsiO 只有php-fpm沒有正確安裝，所以無法啟動之。下面試圖單獨安裝。 [root@AY14022011465274454aZ ~]# yum install php-fpm Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.tuna.tsinghua.edu.cn * updates: mirrors.aliyun.com * webtatic: uk.repo.webtatic.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package php-fpm.x86_64 0:5.3.3-48.el6_8 will be installed --> Processing Dependency: php-common(x86-64) = 5.3.3-48.el6_8 for package: php-fpm-5.3.3-48.el6_8.x86_64 --> Running transaction check ---> Package php-common.x86_64 0:5.3.3-48.el6_8 will be installed --> Processing Conflict: php56w-common-5.6.26-1.w6.x86_64 conflicts php-common < 5.6 --> Finished Dependency Resolution Error: php56w-common conflicts with php-common You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest # yum install php56w-fpm # service php-fpm start Starting php-fpm: Failed loading /usr/lib64/php/modules/ZendGuardLoader.so: /usr/lib64/php/modules/ZendGuardLoader.so: undefined symbol: zend_get_hash_value [ OK ] （這個錯誤信息是怎麼回事？此後一直伴隨，好在沒有其它影響，先不管它） ============ 後續： 1、執行數據庫操作時，找不到PDO模塊 試著用下面指令 # yum install -y libxml2-devel openssl-devel libcurl-devel libjpeg-devel libpng-devel libicu-devel openldap-devel freetype freetype-devel # --沒用 # yum install php56w.x86_64 php56w-cli.x86_64 php56w-common.x86_64 php56w-gd.x86_64 php56w-ldap.x86_64 php56w-mbstring.x86_64 php56w-mcrypt.x86_64 php56w-mysql.x86_64 php56w-pdo.x86_64 #--出錯 # yum install php56w-pdo #--成功 重啟php-fpm服務，這次yii出現新的錯誤 CDbConnection failed to open the DB connection: could not find driver # yum install php56w-mysql 重啟服務，這次yii不出錯了，但渲染一小塊內容，確切地說，只渲染action自己的view的那一塊東西，layout/main.php的沒過來。 # yum install php56w-mbstring 這次渲染正確了。 發現在飯店查詢時出現錯誤： include(DOMDocument.php): failed to open stream: No such file or directory # yum install php56w-dom 成功了。（估計是在解析xml的時候出錯了。） ==================================== 以上是為記錄。留作備忘。http://xxxxxx/Linuxjc/1165877.html TechArticle
