安装 php-5.2.8

启动 php-cgi

对于低版本 php 如: php5.2 启动自带 fastcgi(./configure –enable-fastcgi):

php-cgi -b 127.0.0.1:9000
/usr/local/php/bin/php-cgi -b /tmp/php.socket

wget http://php-fpm.org/downloads/php-5.2.8-fpm-0.5.10.diff.gz（我的php为5.2.8）
tar-xzvf php-5.2.8.tar.gz (解压包php-5.2.8,将生成目录php-5.2.8)
gunzip php-5.2.8-fpm-0.5.10.diff.gz (解压包php-5.2.8-fpm-0.5.10.diff)
patch-d php-5.2.8 -p1 < php-5.2.8-fpm-0.5.10.diff(给php-5.2.8的源码打上fpm补丁)
./configure –enable-fpm

./configure –prefix=/usr/local/php –enable-fastcgi –enable-fpm

安装 freetype

http://sourceforge.net/projects/freetype/
tar zxf freetype-2.5.5.tar.gz
cd freetype-2.5.5
./configure
make && make install

http://sourceforge.net/projects/libpng/
cd libpng-1.6.29
./configure
make && make install

https://github.com/libgd/libgd/releases
cd libgd-2.2.4
./configure --with-png=/usr/local/lib --with-freetype=/usr/local/lib
make && make install

make[2]: *** [gd_gd2.lo] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

​
​ ./configure –prefix=/usr/local/php –enable-fastcgi –with-mysql=/usr/local/lib –with-freetype-dir=/usr/local/lib

删除 php
sudo rm -rf /usr/local/php
启动 php-cgi
/usr/local/php/bin/php-cgi.dSYM -b 127.0.0.1:9000&

安装 php5.2.17

安装 php-fpm
curl -O https://php-fpm.org/downloads/php-5.2.17-fpm-0.5.14.diff.gz
gunzip php-5.2.17-fpm-0.5.14.diff.gz
patch -d php-5.2.17 -p1 < php-5.2.17-fpm-0.5.14.diff

cd php-5.2.17
./configure –prefix=/usr/local/php –enable-fastcgi –enable-fpm
make
sudo make install

启动
/usr/local/php/sbin/php-fpm start

brew install mysql 启动
brew install homebrew/versions/

mysql.server

php 编译时报错信息 ./configure
make: *** [ext/dom/node.lo] Error 1
curl -o php-5.x.x.patch https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt

curl -o php-5.2.16.patch https://mail.gnome.org/archives/xml/2012-August/txtbgxGXAvz4N.txt
cd php-5.2.16
patch -p0 -b < ../php-5.2.16.patch

新增 inotify php扩展

此扩展用于监听 php 文件变化.

gdb 调试利器

首先需要开启 ulimit core dump.
一般Linux默认情况程序出错不会输出core dump文件
ulimit -c unlimited

echo "/web/wwwroot/corefile/core-%e-%p-%t" > /proc/sys/kernel/core_pattern

执行 ulimit -c unlimited 用于抓取 core dump 文件

gdb php core 分析

gdb php -c core.31656

gdb --core core-php7-9744-1467884917 /usr/local/php7/bin/php

编辑修改1 to 0
/etc/sysctl.d/10-ptrace.conf
重启
service procps restart

在 docker ubuntu 中:
sysctl -p /etc/sysctl.conf
sysctl: setting key “fs.file-max”: Read-only file system
sysctl: setting key “kernel.core_pattern”: Read-only file system
sysctl: setting key “kernel.core_uses_pid”: Read-only file system
echo 1 > /proc/sys/kernel/core_uses_pid
-bash: /proc/sys/kernel/core_uses_pid: Read-only file system
无法修改系统变量，方法是启动 docker 时添加-privileged参数已获得提权.

若想 backtrace php 需要编译时添加--enable-debug.
./configure –prefix=/usr/local/php7-debug
–with-config-file-path=/usr/local/php7-debug/etc
–enable-fpm
–with-fpm-user=php7-debug
–with-fpm-group=php7-debug
–with-openssl
–with-pdo-mysql
–with-iconv=/usr/local/lib/libiconv
–with-curl
–enable-mbstring
–enable-debug
–enable-ftp
–with-mcrypt

./configure –with-php-config=/usr/local/php7-debug/bin/php-config –enable-swoole-debug
/usr/local/php7-debug/lib/php/extensions/debug-non-zts-20160303/
/usr/local/php7/lib/php/extensions/no-debug-non-zts-20160303/

ab 测试相关问题

ab 已添加 ‘-k’ 参数，但仍然报如下错误信息
apr_pollset_poll: The timeout specified has expired (70007)
修改系统变量
vim /etc/sysctl.conf
net.ipv4.netfilter.ip_conntrack_max = 655360
使配置生效
sysctl -p /etc/sysctl.conf
