nginx+php-fpm不记录php错误日志error log怎么办?
遇到问题,nginx中不记录php错误日志,php由php-fpm来控制执行,因此nginx在前端无法记录php错误日志,如何解决这个问题?
将架构从apache+mod_php迁移到nginx+fpm上,会发现如果php脚本出错,nginx的eror_log里不会有记录,只在access_log里记录了500状态码。
原因:nginx将php的脚本执行通过fastcgi转到fpm上,所以出错的信息不会记录在nginx的error_log中。
下面介绍下配置fpm错误日志的方法。
参考:
下面具体介绍下php-fpm下记录php错误日志的配置方法与步骤。
php5-fpm.conf
php5-fpm的错误日志是在php5-fpm.conf全局配置中进行设置,查看php5-fpm.conf日志:
复制代码 代码示例:
;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;
[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
;pid = run/php-fpm.pid
pid = /var/run/php5-fpm.pid
; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
; error_log = log/php-fpm.log
#配置error_log,设置error_log的存放位置
error_log = /var/log/fpm/php5-fpm.error.log
; syslog_facility is u
sed to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon
; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm
; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
#错误级别(生产环境下应该提高错误级别,推荐error)
log_level = notice
#表示在emergency_restart_interval所设时间内出现SIGSEGV或者SIGBUS错误的php-cgi进程数如果超过emergency_restart_threshold个,php-fpm就会优雅重启
emergency_restart_threshold = 60
emergency_restart_interval = 60s
; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0
; The maximum number of processes FPM will fork. This has been design to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
; process.max = 128
; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
#后台执行fpm,设置为yes
daemonize = yes
pool.d目录下配置文件(例如:www.conf)
1)保证配置文件中一个参数的开启,参数定义看英文注释:
复制代码 代码示例:
; Redirect worker stdout and stderr into main error log. If not set, stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
catch_workers_output = yes
2)同时可以开启access_log和slow_log
复制代码 代码示例:
access.log = /var/log/fpm/php5-fpm.access.log
; The access log format.
; The following syntax is allowed
; %%: the '%' character
; %C: %CPU used by the request
; it can accept the following format:
; - %{user}C for user CPU only
; - %{system}C for system CPU only
; - %{total}C for user + system CPU (default)
; %d: time taken to serve the request
; it can accept the following format:
; - %{seconds}d (default)
; - %{miliseconds}d
; - %{mili}d
; - %{microseconds}d
; - %{micro}d
; %e: an environment variable (same as $_ENV or $_SERVER)
; it must be associated with embraces to specify the name of the env
; variable. Some exemples:
; - server specifics like: %{REQUEST_METHOD}e or %{SERVER_PROTOCOL}e
; - HTTP headers like: %{HTTP_HOST}e or %{HTTP_USER_AGENT}e
; %f: script filename
; %l: content-length of the request (for POST request only)
; %m: request method
; %M: peak of memory allocated by PHP
; it can accept the following format:
; - %{bytes}M (default)
; - %{kilobytes}M
; - %{kilo}M
; - %{megabytes}M
; - %{mega}M
; %n: pool name
; %o: ouput header
; it must be associated with embraces to specify the name of the header:
; - %{Content-Type}o
; - %{X-Powered-By}o
; - %{Transfert-Encoding}o
; - ....
; %p: PID of the child that serviced the request
; %P: PID of the parent of the child that serviced the request
; %q: the query string
; %Q: the '?' character if query string exists
; %r: the request URI (without the query string, see %q and %Q)
; %R: remote IP address
; %s: status (response code)
; %t: server time the request was received
; it can accept a strftime(3) format:
; %d/%b/%Y:%H:%M:%S %z (default)
; %T: time the log has been written (the request has finished)
; it can accept a strftime(3) format:
; %d/%b/%Y:%H:%M:%S %z (default)
; %u: remote user
;
; Default: "%R - %u %t "%m %r" %s"
;access.format = %R - %u %t "%m %r%Q%q" %s %f %{mili}d %{kilo}M %C%%
; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
slowlog = /var/log/fpm/php5-fpm.log.slow
; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
request_slowlog_timeout = 3
附,fpm日志按天分割脚本
复制代码 代码示例:
#!/bin/bash -
#1.fpm日志存放路径
php5_fpm_path="/var/log/php5-fpm"
path_array=($php5_fpm_path)
#2.日志标识前缀数组
icontact_fpm_sign="test"
test_fpm_sign="php5-fpm"
prefix_array=($icontact_fpm_sign $test_fpm_sign)
#3.日志success or slow 标识后缀数组
bool_array=("access" "slow" "error")
#4.
nginx日志切割备份后缀
postfix=`date +%Y%m%d`".log"
#5.备份当前的
日志文件,重命名改为日期后缀
for path in ${path_array[*]}
do
for prefix in ${prefix_array[*]}
do
for bool in ${bool_array[*]}
do
file=$path/$prefix.$bool.log
backfile=$path/$prefix.$bool.$postfix
if [ -e $file ]
then
mv $file $backfile
fi
done
done
done
#6.查找nginx进程号,让其产生新的日志文件
fpm_pid=`ps -aux |grep -E 'php-fpm: master process'|grep -v 'grep'|
linuxjishu/13830.html target=_blank class=infotextkey>awk '{print $2}'`
#USR1:Reopen log files,刷新nginx日志文件
kill -USR1 $fpm_pid
问题
为了减少线上服务器的错误信息输出,将php-fpm.conf的Log_level = error,这种配置在php5-fpm的错误日志里再也看不到错误信息了。
原因定位
将Log_level = notice后的错误日志信息截图:
fpm将php中warning或error的错误全部定位成了notice级别,所以线上想看fpm的错误日志只能将错误级别定位成notice了。
