yum安装下的nginx，如何添加模块，和添加第三方模块

背景：centos7下yum直接安装的nginx，添加新模块

1、查看nginx版本模块
nginx -V

2、下载一个同版本的可编译的nginx
cd /home/ngadm
wget http://nginx.org/download/nginx-1.12.2.tar.gz
tar zxvf nginx-1.12.2.tar.gz && cd nginx-1.12.2

3、备份、备份、备份
备份文件
mv /usr/sbin/nginx /usr/sbin/nginx.20180720
cp -r /etc/nginx /etc/nginx.20180720

4、检查模块是否支持，比如这次添加 limit 限流模块 和 stream 模块：
./configure –help | grep limit

ps：-without-http_limit_conn_module disable 表示已有该模块，编译时，不需要添加

./configure –help | grep stream

ps：–with-stream enable 表示不支持，编译时要自己添加该模块

根据第二步查到已有的模块，加上本次需新增的模块，那么最终结果如下：

./configure –user=nginx –group=nginx –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 –with-stream –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-debug

以上编译时，如出现缺少依赖，一般需要安装以下模块，安装完再次编译：
yum -y install libxml2 libxml2-dev libxslt-devel
yum -y install gd-devel
yum -y install perl-devel perl-ExtUtils-Embed
yum -y install GeoIP GeoIP-devel GeoIP-data

5、编译通过，继续验证
继续输入：make -j2
禁止：千万不要继续输入“make install”，以免现在的nginx出现问题
以上完成后，会在objs目录下生成一个nginx文件，先验证：
objs/nginx -t
objs/nginx -V

6、文件替换，并重启
以上成功后：
cp objs/nginx /usr/sbin/
nginx -s reload

重启：
nginx -s stop && nginx

补充：添加第三方模块时，先下载需要的模块，例如：echo模块
cd /usr/local/src
wget https://github.com/openresty/echo-nginx-module/archive/v0.61.tar.gz
tar zxvf v0.61.tar.gz

然后在编译时，加上模块的路径：
./configure –user=nginx –group=nginx –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 –with-stream –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-debug –add-module=/usr/local/src/echo-nginx-module-0.61
