yum安装nignx 添加模块（yum安装nmap）

目前使用的nginx版本是1.20.1 ， 在实现四层反向代理的时候用到stream模块

，但是检查配置的时候报错，没有stream模块，所以写此篇文章记录一下

[root@7-22 ~]# nginx -t
nginx: [emerg] unknown directive "stream" in /etc/nginx/nginx.conf:85
nginx: configuration file /etc/nginx/nginx.conf test failed

步骤一：首先查看自己nginx的版本，然后下载一个和自己版本一样的nginx tar包

[root@7-22 ~]# nginx -v
nginx version: nginx/1.20.1                //检查版本
[root@7-22 opt]# cd /opt && wget http://nginx.org/download/nginx-1.20.1.tar.gz 
   // 把tar包下在/opt 目录下 ，根据个人习惯调整目录
[root@7-22 opt]# tar zxvf nginx-1.20.1.tar.gz     //解压tar包

步骤二：备份原文件、安装依赖

[root@7-22 ~]# mv /usr/sbin/nginx /usr/sbin/nginx.bak
[root@7-22 ~]#  cp -r /etc/nginx  /etc/nginx.bak
[root@7-22 ~]# yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++   openssl-devel cmakepcre-develnanowget  gcc gcc-c++ ncurses-devel per redhat-rpm-config.noarch

步骤三：进入解压的nginx目录里面，用./configure重新编译安装nginx

[root@7-22 nginx-1.20.1]# ./configure --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-compat --with-debug --with-file-aio --with-google_perftools_module --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_degradation_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module=dynamic --with-http_mp4_module --with-http_perl_module=dynamic --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-http_xslt_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-stream_ssl_preread_module --with-threads --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' --with-stream 

报错解决：

1../configure: error: the HTTP image filter module requires the GD library.You can either do not enable the module or install the libraries.

yum -y install gd-devel

2../configure: error: the invalid value in --with-ld-opt="-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E"

yum -y install redhat-rpm-config.noarch

3../configure: error: perl module ExtUtils::Embed is required

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

4../configure: error: the Google perftools module requires the Google perftoolslibrary. You can either do not enable the module or install the library.

yum  -y install gperftools-devel

注意：//解决完报错别忘了再重新编译，重新执行一遍步骤三

出现类似下面的命令说明编译没问题了

 + perl version: This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-linux-thread-multi
 + perl interpreter multiplicity found
checking for Google perftools ... found

最后

[root@7-22 nginx-1.20.1]# make install     
[root@7-22 nginx-1.20.1]# nginx -t            //再次检查
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful    //可以看到，success

大功告成！！！
