安装php，nginx 带debug
在CentOS6.4下使用gdb进行调试的时候，
使用bt(breaktrace)命令时，会弹出如下的提示：
头一天提示：
Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.107.el6.i686
问题没解决，第二天提示：
Missing separate debuginfos, use: debuginfo-install glibc-2.12-1.132.el6.i686
但是直接按提示使用 debuginfo-install glibc-2.12-1.132.el6.i686 去安装的时候会报如下的信息：
Loaded plugins: fastestmirror, refresh-packagekit
Loading mirror speeds from cached hostfile
* base: mirrors.yun-idc.com
* extras: mirrors.yun-idc.com
* updates: mirrors.yun-idc.com
Checking for new repos for mirrors
No debuginfo packages available to install
使用yum来进行安装：
sudo yum --nogpgcheck --enablerepo=debug install glibc-debuginfo
却提示：Error Downloading Packages:
glibc-debuginfo-common-2.12-1.132.el6.i686: failure: glibc-debuginfo-common-2.12-1.132.el6.i686.rpm from debug: [Errno 256] No more mirrors to try.
使用yum install glibc安装，发现只是安装了一些基本库，不包含 glibc-debuginfo
后来搜索发现需要先修改“/etc/yum.repos.d/CentOS-Debuginfo.repo”文件的enable=1
文件内容如下：
- # CentOS-Debug.repo
- #
- # The mirror system uses the connecting IP address of the client and the
- # update status of each mirror to pick mirrors that are updated to and
- # geographically close to the client. You should use this for CentOS updates
- # unless you are manually picking other mirrors.
- #
- # All debug packages from all the various CentOS-5 releases
- # are merged into a single repo, split by BaseArch
- #
- # Note: packages in the debuginfo repo are currently not signed
- #
- [debug]
- name=CentOS-6 - Debuginfo
- baseurl=http://debuginfo.centos.org/6/$basearch/
- gpgcheck=1
- gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-Debug-6
- enabled=1
保存之后，使用 debuginfo-install glibc-2.12-1.132.el6.i686 安装，输出如下：
- Loaded plugins: fastestmirror, refresh-packagekit
- Loading mirror speeds from cached hostfile
- * base: mirrors.yun-idc.com

OK，问题解决。
第二次安装总结：
1、需要先修改“/etc/yum.repos.d/CentOS-Debuginfo.repo”文件的enable=1；
2、使用 sudo yum install glibc 安装；
3、使用 debuginfo-install glibc-2.12-1.132.el6.i686 安装。
测试，安装成功。 下面不太好了

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.40.tar.gz
tar -zxvf pcre-8.38.tar.gz
cd pcre-8.38 && ./configure && make && make install
2.安装zlib库
cd /usr/local/
wget http://zlib.net/zlib-1.2.8.tar.gz
tar -zxvf zlib-1.2.8.tar.gz && cd zlib-1.2.8
./configure && make && make install
3.安装ssl
cd /usr/local/
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar -zxvf openssl-1.0.1c.tar.gz && cd openssl-1.0.1c
./config && make && make install
4.安装nginx
Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个，下面是把 Nginx 安装到 /usr/local/nginx 目录下的详细步骤：
cd /usr/local/
wget http://nginx.org/download/nginx-1.2.8.tar.gz
tar -zxvf nginx-1.2.8.tar.gz && cd nginx-1.2.8
./configure --prefix=/usr/local/nginx --with-pcre=/home/source/pcre-8.39 --with-zlib=/home/source/zlib-1.2.8 && make && make install
whereis nginx
--with-pcre=/usr/src/pcre-8.21 指的是pcre-8.21 的源码路径。
--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源码路径。
编译时需添加-gdwarf-2和-g3两个参数。
加了-g3的参数后，gcc编译的时候，会将扩展的debug 信息编译进二进制文件里面，包括宏定义信息。

为方便nginx启动，重启

5 安装php
tar zvxf php-5.5.38.tar.gz && cd php-5.5.38
cd /usr/local/php
cp etc/php-fpm.conf.default etc/php-fpm.conf
vi etc/php-fpm.conf
修改
user = www-data
group = www-data
如果www-data用户不存在，那么先添加www-data用户
groupadd www-data
useradd -g www-data www-data
/usr/local/php/sbin/php-fpm
/usr/local/php/sbin/php-fpm -c /usr/local/php/etc/php.ini -y /usr/local/php/etc/php-fpm.conf
-bash: /usr/bin/php: No such file or directory
vi /etc/profile
在文件底部增加一行配置
export PATH=/usr/local/php/bin:$PATH
保存退出
source /etc/profile
./configure --prefix=/usr/local/php --with-php-config=/usr/local/php/bin/php-config --enable-sockets
make && make install
master进程可以理解以下信号
INT, TERM 立刻终止 QUIT 平滑终止 USR1 重新打开日志文件 USR2 平滑重载所有worker进程并重新载入配置和二进制模块
示例：
php-fpm 关闭：
kill -INT `cat /usr/local/php/var/run/php-fpm.pid`
php-fpm 重启：
kill -USR2 `cat /usr/local/php/var/run/php-fpm.pid`
tar -xvzf bison-2.6.4.tar.gz
# tar xf re2c-0.13.7.5.tar.gz
# cd re2c-0.13.7.5
# ./configure
#make && make install
php-fpm 5.4.7 如何关闭 重启？
查看php-fpm进程数：
ps aux | grep -c php-fpm
6 zend opcache
[opcache]
zend_extension = /data/app/php5/lib/php/extensions/no-debug-zts-20121212/opcache.so
opcache.enable=1
opcache.memory_consumption = 64
opcache.interned_strings_buffer = 8
opcache.max_accelerated_files = 4000
opcache.revalidate_freq = 60
opcache.fast_shutdown = 1
opcache.enable_cli = 1
7.启动
确保系统的 80 端口没被其他程序占用，
/usr/local/nginx/sbin/nginx
检查是否启动成功：
netstat -ano|grep 80 有结果输入说明启动成功
打开浏览器访问此机器的 IP，如果浏览器出现 Welcome to nginx! 则表示 Nginx 已经安装并运行成功。
7.重启
/usr/local/nginx/sbin/nginx –s reload
8.修改配置文件
cd /usr/local/nginx/conf
vi nginx.conf
9.常用配置
#nginx运行用户和组
user www www;
#启动进程,通常设置成和cpu的数量相等
worker_processes 4;
#全局错误日志及PID文件
pid /var/run/nginx.pid;
error_log /var/log/nginx/error.log;

首先要找到php-fpm.conf配置文件，查看pid的配置路径(不是安装路径)，然后把下面对应的地方改掉才能正常执行。
[root@DO-SG-H1 ~]# ps aux | grep php-fpm
root 11799 0.0 0.0 103248 880 pts/0 S+ 13:51 0:00 grep --color php-fpm
root 11973 0.0 0.0 417748 964 ? Ss Jun01 0:20 php-fpm: master process (/etc/php-fpm.conf)
cat /etc/php-fpm.conf
看到
pid = /var/run/php-fpm/php-fpm.pid
php-fpm 启动：
/usr/local/php/sbin/php-fpm
php-fpm 关闭：
kill -INT `cat /var/run/php-fpm/php-fpm.pid`
php-fpm 重启：
kill -USR2 `cat /var/run/php-fpm/php-fpm.pid`
查看php-fpm进程数：
ps aux | grep -c php-fpm
=============================
[root@DO-SG-H1 ~]# find / -name 'php-fpm' -type d
/var/log/php-fpm
/var/run/php-fpm
用这个find命令查找出来的路径是不对的
