我一直关注this tutorial 为我的每个 wordpress 多站点安装设置多个 PHP-FPM 主服务器，以便它们可以在 APC 缓存和其他选项方面相互独立运行。
按照信中的说明进行操作后，每个新的 php5-fpm init.d 脚本实际上不会初始化或执行任何操作。/var/run/php5-fpm-master2.pid 和 php5-fpm-master2.sock 也没有被创建。考虑到我已经按照指示进行操作，我假设他的 distro/package 版本不同，或者我在字里行间遗漏了一些东西。
有人愿意分享如何在 Ubuntu 14.04 上正确设置多个 PHP-FPM 主机（来自 apt-get 的标准 php5-fpm）吗？

我用的不是 Ubuntu，而是 Debian Jessie，这里应该是一样的。
首先，转到/etc/php5/fpm/pool.d。
在那里你必须创建你的池，例如。 G。一个文件名为www1.conf:
[www1]
user = www1
group = www1
listen = /var/run/php5-fpm-www1.sock
listen.owner = www1
listen.group = www1
listen.allowed_clients = 127.0.0.1
pm = ondemand
pm.max_children = 100
pm.process_idle_timeout = 5s;
chdir = /
创建第二个，例如。 G。文件名www2.conf:
[www2]
user = www2
group = www2
listen = /var/run/php5-fpm-www2.sock
listen.owner = www2
listen.group = www2
listen.allowed_clients = 127.0.0.1
pm = ondemand
pm.max_children = 100
pm.process_idle_timeout = 5s;
chdir = /
现在转到/etc/php5/fpm 并删除其中的php-fpm.conf（在单独的目录中备份会很有用）。现在创建文件php-fpm-www1.conf，内容如下：
[global]
pid = /var/run/php5-fpm-www1.pid
error_log = /var/log/php5-fpm-www1.log
syslog.ident = php-fpm-www1
log_level = notice
emergency_restart_threshold = 10
emergency_restart_interval = 1m
include=/etc/php5/fpm/pool.d/www1.conf
与此类似，创建文件php-fpm-www2.conf：
[global]
pid = /var/run/php5-fpm-www2.pid
error_log = /var/log/php5-fpm-www2.log
syslog.ident = php-fpm-www2
log_level = notice
emergency_restart_threshold = 10
emergency_restart_interval = 1m
include=/etc/php5/fpm/pool.d/www2.conf
这就是您需要的完整配置。最重要的部分是正确的初始化脚本。在 Debian 上，我只是复制了默认的 /etc/init.d/php5-fpm。

### END INIT INFO
在这里您必须将第 2 行和第 7 行更改为您的脚本名称。
配置：
PATH=/sbin:/usr/sbin:/bin:/usr/bin
DESC="PHP5 FastCGI Process Manager"
NAME=php5-fpm-www1
BIN=php5-fpm
DAEMON=/usr/sbin/$BIN
DAEMON_ARGS="--daemonize --fpm-config /etc/php5/fpm/php-fpm-www1.conf"
CONF_PIDFILE=$(sed -n 's/^pid\s*=\s*//p' /etc/php5/fpm/php-fpm-www1.conf)
PIDFILE=${CONF_PIDFILE:-/run/php5-fpm-www1.pid}
TIMEOUT=30
SCRIPTNAME=/etc/init.d/$NAME
将NAME 变量更改为您的脚本名称，并将BIN 变量添加为您的bin 文件的名称。此外，编辑 DAEMON 以匹配 $BIN 而不是 $NAME。 DAEMON:ARGS、CONF_PIDFILE 和 PIDFILE 必须进行编辑以匹配您在 /etc/php5/fpm 中的配置。
现在脚本应该已经启动了特定的 PHP5-FPM master。
我的问题是/etc/init.d/php5-fpm-www1 stop 也确实阻止了www2 的主人。
要解决这个问题，您必须在 init 脚本中编辑 do_stop() 函数：
do_stop()
{
# Return
# 0 if daemon has been stopped
# 1 if daemon was already stopped
# 2 if daemon could not be stopped
# other if a failure occurred
start-stop-daemon --stop --quiet --retry=QUIT/$TIMEOUT/TERM/5/KILL/5 --pidfile $PIDFILE --name $NAME
RETVAL="$?"
[ "$RETVAL" = 2 ] && return 2
# Wait for children to finish too if this is a daemon that forks
# and if the daemon is only ever run from this initscript.
# If the above conditions are not satisfied then add some other code
# that waits for the process to drop all resources that could be
# needed by services started subsequently. A last resort is to
# sleep for some time.
start-stop-daemon --stop --quiet --oknodo --retry=0/30/TERM/5/KILL/5 --name $NAME --exec $DAEMON
[ "$?" = 2 ] && return 2
# Many daemons don't delete their pidfiles when they exit.
rm -f $PIDFILE
return "$RETVAL"
}
这里我必须将--name $NAME 添加到第 17 行的第二个start-stop-daemon 命令中。
