php-fpm failed to start:

Recommended: "PHP Tutorial"

After installing LNMP today, I found that php-fpm could not be started.

The error is as follows:

           [root@localhost php-5.4.37]# service php-fpm start
           Starting php-fpm ................................... failed

Compile and install

The compilation parameters are as follows:

./configure --prefix=/usr/local/php --with-config-file-path=/etc/php --enable-fpm --with-fpm-user --with-fpm-group=php-fpm --with-mysql=/usr/local/mysql/ --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --with-curl --enable-ftp --enable-mbstring --enable-exif --disable-ipv6
make && make install

2. Copy the configuration file and startup script

mv /usr/local/php/etc/{php-fpm.conf.default,php-fpm.conf}
cp /usr/local/src/php-5.4.37/sapi/fpm/init.php-fpm /etc/init.d/php-fpm
chmod 755 /etc/init.c/php-fpm
chkconfig --add php-fpm
service php-fpm start

and report an error when starting.

It can be started directly during installation. Today is special.

Then restart it, and the error is as follows:

[root@localhost php-5.4.37]# service php-fpm restart
Gracefully shutting down php-fpm warning, no pid file found - php-fpm is not running ?
Starting php-fpm [16-May-2015 19:23:22] ERROR: unable to bind listening socket for address '127.0.0.1:9000': Address already in use (98)
[16-May-2015 19:23:22] ERROR: FPM initialization failed
failed

## 了 View the/usr/local/pHP/var/run directory, there are corresponding correspondence below pid file.

But the error message shows that there is no such pid file. Checking the log also shows that php-fpm is running.

Then check the configuration file for errors /usr/local/php/sbin/php-fpm -t Check that there are no syntax errors, and then check the /etc/init.d/php-fpm file The contents and paths of those files are all written in the format @xxx@/php-fpm.pid.

Then change it to an absolute path, killall php-fpm, and then start php-fpm, it succeeds.
