怎样编译安装nghttp2

2016年7月28日 | 分类: 【技术】

【依赖】

yum安装OpenSSL:

参考:http://amon.org/openssl

编译安装zlib:

参考:http://amon.org/zlib

yum安装Xz:

yum install xz

参考:http://amon.org/xz

务必yum安装Xz,否则可能导致yum失效。

编译安装icu:

参考:http://amon.org/icu

注意:ICU 只能在 GCC4.8.5下编译成功。因此仅在编译nghttp2时启用GCC8.3.0。重新编译时重新解压开始编译。

编译安装libxml2:

参考:http://amon.org/libxml2

编译安装CUnit:

参考:http://amon.org/cunit

编译安装libevent:

参考:http://amon.org/libevent

编译安装spdylay:

注意:spdylay 只能在 GCC4.8.5下编译成功。因此仅在编译nghttp2时启用GCC8.3.0。重新编译时重新git获得源码开始编译。

编译安装spdylay:

git clone https://github.com/tatsuhiro-t/spdylay.git && cd spdylay
autoreconf -i && automake && autoconf
export ZLIB_CFLAGS="-I/usr/include" ZLIB_LIBS="-L/usr/lib -lz" OPENSSL_CFLAGS="-I/usr/include/openssl" OPENSSL_LIBS="-L/usr/lib -lssl -lcrypto" CUNIT_CFLAGS="-I/usr/local/include/CUnit" CUNIT_LIBS="-L/usrlocal/lib/cunit -lcunit" LIBEVENT_OPENSSL_CFLAGS="-I/usr/include" LIBEVENT_OPENSSL_LIBS="-L/usr/lib -levent_openssl -levent"
./configure && make && make install

如果configure时报错:

spdylay_ssl.h:36:25: fatal error: openssl/ssl.h: No such file or directory

只要yum安装openssl-devel即可解决问题,而且不与编译版的openssl冲突:

yum install openssl-devel

如果make时报错:

libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6

参考:http://amon.org/libtool

编译成功后相关文件路径:

/usr/local/include/spdylay/spdylayver.h
/usr/local/lib/libspdylay.so.7.2.0
/usr/local/lib/pkgconfig/libspdylay.pc

更新系统动态连接库配置:

echo /usr/local/lib >> /etc/ld.so.conf && ldconfig

测试:

运行一下SPDY的反向代理程序,看看是否工作良好:

shrpx

输出:

Usage: shrpx [-Dh] [-s|--client|-p] [-b <HOST,PORT>]
             [-f <HOST,PORT>] [-n <CORES>] [-c <NUM>] [-L <LEVEL>]
             [OPTIONS...] [<PRIVATE_KEY> <CERT>]

A reverse proxy for SPDY/HTTPS.

[FATAL] Too few arguments

出现这个提示说明spdylay已经安装正常。

编译安装完成。

编译安装Jansson:

参考:http://amon.org/jansson

编译安装Boost:

参考:http://amon.org/boost

务必编译完成,不能简单复制。

参考:https://www.nghttp2.org/documentation/libnghttp2_asio.html

否则编译 nghttp2 时 make 时 报错:

...
variadic templates only available with -std=c++11 or -std=gnu++11
...

yum安装python-setuptools:

Python2环境:

yum install python-setuptools

Python3环境:

yum install python3-setuptools

如果不安装python-setuptools,在编译nghttp2时会报错:

ImportError “No Module named Setuptools”

参考:http://stackoverflow.com/questions/14426491/python-3-importerror-no-module-named-setuptools

UPDATE (Oct 2014): Distribute has been merged with setuptools 0.7, so just get setuptools for both Python 2.7 and 3.x

编译安装libc-ares:

参考:http://amon.org/libc-ares

早先版本的nghttp2并不需要这个libc-ares库,但最新版本必需这个库。

【安装】

卸载系统已装版本(如有):

rpm -e --nodeps nghttp2
rpm -e --nodeps nghttp2-devel

从源码编译安装:

参考:https://www.nghttp2.org/documentation/package_README.html
参考:http://linuxfromscratch.org/blfs/view/cvs/basicnet/nghttp2.html
参考:https://www.nghttp2.org/documentation/libnghttp2_asio.html

源码包方式:

下载:https://github.com/nghttp2/nghttp2/releases/

wget https://github.com/nghttp2/nghttp2/releases/download/v1.34.0/nghttp2-1.34.0.tar.gz && tar -zxf nghttp2-1.34.0.tar.gz && cd nghttp2-1.34.0

./configure --with-boost-asio --enable-asio-lib --with-boost-libdir=/usr/lib
make && make install

注意:./configure 时,务必 applications 项 为 yes ,才能保证 nghttp2 安装成功。

创建软链接:

ln -f /usr/local/lib/pkgconfig/libnghttp2.pc /usr/lib/pkgconfig/libnghttp2.pc

更新系统动态连接库配置:

ldconfig

编译安装完成。

如果 make 时报错:

error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

问题出现于 nghttp2 v1.35.1 ,更新日志里有“src: Require C++14 language feature”。

解决办法:
1. 升级 GCC ,然后编译,参考:http://amon.org/gcc
2. 尝试编译安装较早版本,最近版本 nghttp2 v1.34.0 成功编译通过。

GIT获得源码方式:

nghttp2 v1.35.1 之后使用 GIT 方式,必须升级 GCC 。

git clone https://github.com/tatsuhiro-t/nghttp2.git && cd nghttp2
autoreconf -i && automake && autoconf
export PYTHONPATH=/usr/lib64/python2.7/site-packages/ LIBSPDYLAY_CFLAGS="-I/usr/local/include/spdylay" LIBSPDYLAY_LIBS="-L/usr/local/lib -lspdylay" JANSSON_CFLAGS="-I/usr/local/include" JANSSON_LIBS="-L/usr/local/lib -ljansson" OPENSSL_CFLAGS="-I/usr/include/openssl" OPENSSL_LIBS="-L/usr/lib -lssl -lcrypto" CUNIT_CFLAGS="-I/usr/include/CUnit" CUNIT_LIBS="-L/usr/lib -lcunit"  LIBEVENT_OPENSSL_CFLAGS="-I/usr/include" LIBEVENT_OPENSSL_LIBS="-L/usr/lib -levent_openssl -levent" LIBCARES_CFLAGS="-I/usr/local/include" LIBCARES_LIBS="-L/usr/local/lib -lcares"
./configure --with-boost-asio --enable-asio-lib --with-boost-libdir=/usr/lib && make && make install

注意:./configure 时,务必 applications 项 为 yes ,才能保证 nghttp2 安装成功。

创建软链接:

ln -f /usr/local/lib/pkgconfig/libnghttp2.pc /usr/lib/pkgconfig/libnghttp2.pc

更新系统动态连接库配置:

ldconfig

编译安装完成。

相关文件路径:

/usr/local/include/nghttp2/nghttp2.h
/usr/local/lib/libnghttp2.so.14.9.0
/usr/local/lib/pkgconfig/libnghttp2.pc

【排错】

当make install时报错:error: bad install directory or PYTHONPATH

TEST FAILED: /usr/local/lib64/python2.7/site-packages/ does NOT support .pth files
error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /usr/local/lib64/python2.7/site-packages/

and your PYTHONPATH environment variable currently contains:

    ''

修正:

export PYTHONPATH=/usr/local/lib64/python2.7/site-packages/ LIBSPDYLAY_CFLAGS="-I/usr/local/include/spdylay" LIBSPDYLAY_LIBS="-L/usr/local/lib -lspdylay" JANSSON_CFLAGS="-I/usr/local/include" JANSSON_LIBS="-L/usr/local/lib -ljansson" OPENSSL_CFLAGS="-I/usr/include/openssl" OPENSSL_LIBS="-L/usr/lib -lssl -lcrypto" CUNIT_CFLAGS="-I/usr/include/CUnit" CUNIT_LIBS="-L/usr/lib -lcunit"  LIBEVENT_OPENSSL_CFLAGS="-I/usr/include" LIBEVENT_OPENSSL_LIBS="-L/usr/lib -levent_openssl -levent" LIBCARES_CFLAGS="-I/usr/local/include" LIBCARES_LIBS="-L/usr/local/lib -lcares"
./configure --with-boost-asio --enable-asio-lib --with-boost-libdir=/usr/lib && make && make install

然后顺利编译成功。

如果 configure时报错:configure: error: Could not link against boost_system

在升级 GCC 之前安装 Boost ,不会出现此问题。

在升级 GCC 之后安装 Boost ,yum 安装 boost-devel 可以解决问题:

yum install boost-devel

【配置】

编译安装Apache:

参考:http://amon.org/apache

在编译httpd时加入以下参数即可支持 httpd2 :

 --enable-http2 --with-nghttp2=/usr/local/lib

配置Apache:

打开 /usr/local/apache2/conf/httpd.conf ,编辑:

ServerRoot "/usr/local/apache2"
