#手动修改php.ini文件
手工修改：查找/usr/local/php/etc/php.ini中的extension_dir = "./"
修改为extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下几行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off
修改为output_buffering = On
#自动修改php.ini文件

notice
When this amount of php processes exited with SIGSEGV or SIGBUS ...
10
... in a less than this interval of time, a graceful restart will be initiated.
Useful to work around accidental curruptions in accelerator's shared memory.
1m
Time limit on waiting child's reaction on signals from master
5s
Set to 'no' to debug fpm
yes
Name of pool. Used in logs and stats.
default
Address to accept fastcgi requests on.
Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'
127.0.0.1:9000
Set listen(2) backlog
-1
Set permissions for unix socket, if one used.
In Linux read/write permissions must be set in order to allow connections from web server.
Many BSD-derrived systems allow connections regardless of permissions.
0666
Additional php.ini defines, specific to this pool of workers.
/usr/sbin/sendmail -t -i
0
Unix user of processes
www
Unix group of processes
www
Process manager settings
Sets style of controling worker process count.
Valid values are 'static' and 'apache-like'
static
Sets the limit on the number of simultaneous requests that will be served.
Equivalent to Apache MaxClients directive.
Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi
Used with any pm_style.
128
Settings group for 'apache-like' pm style
Sets the number of server processes created on startup.
Used only when 'apache-like' pm_style is selected
20
Sets the desired minimum number of idle server processes.
Used only when 'apache-like' pm_style is selected
5
Sets the desired maximum number of idle server processes.
Used only when 'apache-like' pm_style is selected
35
The timeout (in seconds) for serving a single request after which the worker process will be terminated
Should be used when 'max_execution_time' ini option does not stop script execution for some reason
'0s' means 'off'
0s
The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
'0s' means 'off'
0s
The log file for slow requests
logs/slow.log
Set open file desc rlimit
65535
Set max core size rlimit
0
Chroot to this directory at the start, absolute path
Chdir to this directory at the start, absolute path
Redirect workers' stdout and stderr into main error log.
If not set, they will be redirected to /dev/null, according to FastCGI specs
yes
How much requests each process should execute before respawn.
Useful to work around memory leaks in 3rd party libraries.
For endless request processing please specify 0
Equivalent to PHP_FCGI_MAX_REQUESTS
1024
Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.
Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)
Makes sense only with AF_INET listening socket.
127.0.0.1
Pass environment variables like LD_LIBRARY_PATH
All $VARIABLEs are taken from current environment

#=======================在不停止Nginx服务的情况下平滑变更Nginx配置======================================
1、修改/usr/local/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：
/usr/local/nginx/sbin/nginx -t
/*
如果屏幕显示以下两行信息，说明配置文件正确：
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
*/
2、平滑重启：
①、对于Nginx 0.8.x版本，现在平滑重启Nginx配置非常简单，执行以下命令即可：
/usr/local/nginx/sbin/nginx -s reload
②、对于Nginx 0.8.x之前的版本，平滑重启稍微麻烦一些，按照以下步骤进行即可。输入以下命令查看Nginx主进程号：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
屏幕显示的即为Nginx主进程号，例如：
6302
这时，执行以下命令即可使修改过的Nginx配置文件生效：
kill -HUP 6302
#或者无需这么麻烦，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/nginx/nginx.pid`
#===========================编写每天定时切割Nginx日志的脚本==============================================

#故障1
/usr/local/php/sbin/php-fpm start
Starting php_fpm eAccelerator: Could not allocate 67108864 bytes, the maximum size the kernel allows is 33554432 bytes. Lower the amount of memory request or increase the limit in /proc/sys/kernel/shmmax.
PHP Warning: [eAccelerator] Can not create shared memory area in Unknown on line 0
PHP Fatal error: Unable to start eAccelerator module in Unknown on line 0
failed
#说明
php.ini中设置的eAccelerator，eaccelerator.shm_size="64"，解释：eaccelerator可使用的共享内存大小(单位为MB)，即64M
在Linux下，单个进程的最大内存使用量受/proc/sys/kernel/shmmax中设置的数字限制(单位为字节) /proc/sys/kernel/shmmax = 33554432 （32M）
临时更改该值：
echo 128000000 > /proc/sys/kernel/shmmax
或者
vi /etc/sysctl.conf
kernel.shmmax = 128000000
syscatl -p
