http通道连接mysql_通过http tunnel连接mysql

在/etc/nginx/nginx.conf的第一行加上

load_module /usr/lib64/nginx/modules/ngx_http_proxy_connect_module.so;

nginx -s reload

> ```nginx: [emerg] dlopen() "/usr/lib64/nginx/modules/ngx_http_proxy_connect_module.so" failed (/usr/lib64/nginx/modules/ngx_http_proxy_connect_module.so: cannot open shared object file: No such file or directory) in /etc/nginx/nginx.conf```

又要开始折腾了, 没有ngx_http_proxy_connect_module, google了一把, ngx_http_proxy_connect_module

相当于重新编译nginx, 有几个坑, 不过意外发现有个go的开源库,专门编译nginx,刚好我是go开发,go的库nginx-build, 但是下面说的跟这个库没关系, 只是打个go的广告^_^

(1) 选定对应的nginx源码zip,更改nginx的version, nginx -v

(2) ./configure的编译参数, 需要提前nginx -V复制之前的启动参数下来

(3) 执行path的时候需要看`https://github.com/chobits/ngx_http_proxy_connect_module`的说明,哪个版本用哪个patch

$ git clone https://github.com/chobits/ngx_http_proxy_connect_module.git /root/ngx_http_proxy_connect_module

$ wget http://nginx.org/download/nginx-1.12.2.tar.gz

$ tar -xzvf nginx-1.12.2.tar.gz

$ cd nginx-1.12.2/

$ patch -p1 < /root/ngx_http_proxy_connect_module/patch/proxy_connect.patch

$ ./configure --add-module=/root/ngx_http_proxy_connect_module ·后面接上nginx -V里面的configure arguments·

$ make && make install

$ cp /root/ngx_http_proxy_connect_module

执行过程

$ ./configure --add-dynamic-module=/root/ngx_http_proxy_connect_module --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-file-aio --with-ipv6 --with-http_auth_request_module --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-google_perftools_module --with-debug --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E'

出现各种错误,各种google,最终

yum -y install redhat-rpm-config.noarch

yum -y install libxslt-devel

yum -y install perl-devel perl-ExtUtils-Embed

yum -y install gd-devel

yum -y install geoip-devel

yum -y install gperftools-devel

最后编译只出现warning类的报错才算成功
