Detailed explanation of php-fpm service startup script steps
这次给大家带来php-fpm服务启动脚本步骤详解，php-fpm服务启动脚本的注意事项有哪些，下面就是实战案例，一起来看一下。
先创建自启动文件：/etc/init.d/php-fpm
内容如下：
#! /bin/sh
### BEGIN INIT INFO
# Provides: php-fpm
# Required-Start: $remote_fs $network
# Required-Stop: $remote_fs $network
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: starts php-fpm
# Description: starts the PHP FastCGI Process Manager daemon
### END INIT INFO
prefix=/usr/local/php
exec_prefix=${prefix}
php_fpm_BIN=${exec_prefix}/sbin/php-fpm
php_fpm_CONF=${prefix}/etc/php-fpm.conf
php_fpm_PID=${prefix}/var/run/php-fpm.pid
php_opts="--fpm-config $php_fpm_CONF --pid $php_fpm_PID"
wait_for_pid () {
try=0
while test $try -lt 35 ; do
case "$1" in
'created')
if [ -f "$2" ] ; then
try=''
break
fi
;;
'removed')
if [ ! -f "$2" ] ; then
try=''
break
fi
;;
esac
echo -n .
try=`expr $try + 1`
sleep 1
done
}
case "$1" in
start)
echo -n "Starting php-fpm "
$php_fpm_BIN --daemonize $php_opts
if [ "$?" != 0 ] ; then
echo " failed"
exit 1
fi
wait_for_pid created $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
stop)
echo -n "Gracefully shutting down php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -QUIT `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed. Use force-quit"
exit 1
else
echo " done"
fi
;;
status)
if [ ! -r $php_fpm_PID ] ; then
echo "php-fpm is stopped"
exit 0
fi
PID=`cat $php_fpm_PID`
if ps -p $PID | grep -q $PID; then
echo "php-fpm (pid $PID) is running..."
else
echo "php-fpm dead but pid file exists"
fi
;;
force-quit)
echo -n "Terminating php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -TERM `cat $php_fpm_PID`
wait_for_pid removed $php_fpm_PID
if [ -n "$try" ] ; then
echo " failed"
exit 1
else
echo " done"
fi
;;
restart)
$0 stop
$0 start
;;
reload)
echo -n "Reload service php-fpm "
if [ ! -r $php_fpm_PID ] ; then
echo "warning, no pid file found - php-fpm is not running ?"
exit 1
fi
kill -USR2 `cat $php_fpm_PID`
echo " done"
;;
*)
echo "Usage: $0 {start|stop|force-quit|restart|reload|status}"
exit 1
;;
esac配置php-fpm服务
# 设置权限 chmod 755 /etc/init.d/php-fpm # php-fpm加入服务 chkconfig --add php-fpm # php-fpm 234级别下设置为启动 chkconfig php-fpm on # 查看php-fpm服务当前配置 chkconfig --list php-fpm php-fpm 0:off 1:off 2:on 3:on 4:on 5:on 6:off
php-fpm使用方法
# 启动 service php-fpm start # 关闭 service php-fpm stop # 重启 service php-fpm restart # 重载 service php-fpm reload #检查配置文件 service php-fpm configtest
脚本说明
# Source function library. . /etc/rc.d/init.d/functions # Source networking configuration. . /etc/sysconfig/network
以上量行代码有人会疑问他们到底是做什么的，'.'是source类似于程序中的include和require,将functions里面的方法全部倒入到这边，这边程序便可以使用，例如这边用到的daemon、status。第二行的network实际上就几行，如下
NETWORKING=yes HOSTNAME=E10162
将他们作为变量赋值,判断网卡是否启动，如果你的nginx不走网卡，其实网络这段可以去掉.
