本篇文章給大家介紹一下centOS安裝PHP后，php-fpm啟動失敗的解決方法。有一定的參考價值，有需要的朋友可以參考一下，希望對大家有所幫助。

在centOS6.8上安裝php，出各種問題，光是gcc的版本太低，升級gcc這個，就讓我氣了兩天，翻遍了幾乎所有相關博客總算解決了。還有mysql安裝也沒少踩坑，所以大家還是盡量用centOS7吧，少生氣能多活幾年呢。。。

現在說一下centOS6.8上編譯安裝php7.2.1吧。

1，安裝擴展包并更新系統(我在根目錄下開始的)：

yum install epel-release -y yum update

2,安裝php依賴組件（一段全復制上去，其實掠過也可能沒關系）：

yum -y install wget vim pcre pcre-devel openssl openssl-devel libicu-devel gcc gcc-c++ autoconf 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 krb5-devel libidn libidn-devel openldap openldap-devel nss_ldap jemalloc-devel cmake boost-devel bison automake libevent libevent-devel gd gd-devel libtool* libmcrypt libmcrypt-devel mcrypt mhash libxslt libxslt-devel readline readline-devel gmp gmp-devel libcurl libcurl-devel openjpeg-devel

3，下載php安裝包并解壓：

wget http://am1.php.net/distributions/php-7.2.1.tar.gz tar xvf php-7.2.1.tar.gz

4，進入解壓目錄并開始編譯(編譯千萬不能省，運行出錯了就不能make了，這是我選出來的最靠譜可行的編譯了)：

cd /php-7.2.1

./configure –prefix=/usr/local/php7 –with-config-file-path=/usr/local/php7/etc –with-mcrypt=/usr/include –with-mysql=mysqlnd –with-mysqli=mysqlnd –with-pdo-mysql=mysqlnd –with-gd –with-iconv –with-zlib –enable-xml –enable-bcmath –enable-shmop –enable-sysvsem –enable-inline-optimization –enable-mbregex –enable-fpm –enable-mbstring –enable-ftp –enable-gd-native-ttf –with-openssl –enable-pcntl –enable-sockets –with-xmlrpc –enable-zip –enable-soap –without-pear –with-gettext –enable-session –with-curl –with-jpeg-dir –with-freetype-dir –enable-opcache

5，為了安全保險的給make出來，先更新依賴庫以防萬一：

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel

6，安裝：

make make install

7,關于配置：

cp php.ini-development /usr/local/php7/etc/php.ini cp /usr/local/php7/etc/php-fpm.conf.default /usr/local/php7/etc/php-fpm.conf cp /usr/local/php7/etc/php-fpm.d/www.conf.default /usr/local/php7/etc/php-fpm.d/www.conf

8，加個權限：

chmod +x /etc/init.d/php-fpm

現在試一下，/etc/init.d/php-fpm start

如果php啟動成功了，那你很幸福；如果失敗了，接著往下看。

大概出現的是下圖這個情況吧？

再試一下運行提示的命令，出的問題是ERROR:FPM initialization failed.如下圖：

所以出問題的是php-fpm，機智如我，把我另一個虛擬機（centOS7）上的php-fpm給換上去了，只需要把php的安裝根目錄按照自己的情況改一下就成了（就是這一行：prefix=/usr/local/php）。現在我就無私的把我的php-fpm文件奉獻出來。
