本篇文章给大家介绍一下centOS安装PHP后,php-fpm启动失败的解决方法。有一定的参考价值,有需要的朋友可以参考一下,希望对大家有所帮助。

What should I do if php-fpm fails to start after installing PHP on centOS?

在centOS6.8上安装php,出各种问题,光是gcc的版本太低,升级gcc这个,就让我气了两天,翻遍了几乎所有相关博客总算解决了。还有mysql安装也没少踩坑,所以大家还是尽量用centOS7吧,少生气能多活几年呢。。。

现在说一下centOS6.8上编译安装php7.2.1吧。

1,安装扩展包并更新系统(我在根目录下开始的):

yum install epel-release -y yum update
Copy after login

2,安装php依赖组件(一段全复制上去,其实掠过也可能没关系):

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,下载php安装包并解压:

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

4,进入解压目录并开始编译(编译千万不能省,运行出错了就不能make了,这是我选出来的最靠谱可行的编译了):

cd /php-7.2.1
Copy after login

./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,为了安全保险的给make出来,先更新依赖库以防万一:

yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel
Copy after login

6,安装:

make make install
Copy after login

7,关于配置:

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
Copy after login

8,加个权限:

chmod +x /etc/init.d/php-fpm
Copy after login

现在试一下,/etc/init.d/php-fpm start

如果php启动成功了,那你很幸福;如果失败了,接着往下看。

大概出现的是下图这个情况吧?

再试一下运行提示的命令,出的问题是ERROR:FPM initialization failed.如下图:

所以出问题的是php-fpm,机智如我,把我另一个虚拟机(centOS7)上的php-fpm给换上去了,只需要把php的安装根目录按照自己的情况改一下就成了(就是这一行:prefix=/usr/local/php)。现在我就无私的把我的php-fpm文件奉献出来。
