安装php 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：

保存之后，使用 debuginfo-install glibc-2.12-1.132.el6.i686 安装，输出如下：

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

yum --nogpgcheck --enablerepo=debug install glibc-debuginfo cyrus-sasl-debuginfo keyutils-debuginfo krb5-debuginfo libselinux-debuginfo libssh2-debuginfo libxml2-debuginfo nspr-debuginfo nss-debuginfo nss-softokn-debuginfo nss-util-debuginfo openldap-debuginfo openssl-debuginfo zlib-debuginfo

5 安装php
tar zvxf php-5.4.7.tar.gz
cd php-5.4.7
CFLAGS="-g -gdwarf-2 -g3" CXXFLAGS="-g -gdwarf-2 -g3" ./configure --prefix=/usr/local/php --enable-fpm --disable-pdo --with-curl --enable-debug --enable-opcache

make all install


6.配置php-fpm
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

修改nginx配置文件以支持php-fpm

nginx安装完成后，修改nginx配置文件为,nginx.conf

其中server段增加如下配置，注意标红内容配置，否则会出现No input file specified.错误

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}

php-fpm 5.4.7 如何关闭 重启？

php 5.4.7 下的php-fpm 不再支持 php-fpm 以前具有的 /usr/local/php/sbin/php-fpm (start|stop|reload)等命令，需要使用信号控制：

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`

查看php-fpm进程数：

ps aux | grep -c php-fpm

8.命令行下执行php，提示找不到命令

-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


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

 which php
/usr/bin/php
