二、將上面加粗字體部分進行配置，加粗字體后面為系統的配置文件不需要配置，只需要到 make，千萬不要 make install 。如果make install 會將原來的配置文件覆蓋
事先可以先把這些依賴包下好，配置之后就不會出現下面這些錯誤了
yum -y install gcc make GeoIP GeoIP-devel GeoIP-data perl-devel perl-ExtUtils-Embed gd-devel libxml2 libxslt-devel gperftools pcre-devel openssl openssl-devel
準備新版本的nginx放在/usrr/local/ 下
[root@vm-3]# wget http://nginx.org/download/nginx-1.16.1.tar.gz
[root@vm-3]# tar -xf nginx-1.16.1.tar.gz
[root@vm-3]# cd nginx-1.16.1
[root@vm-3 nginx-1.16.1]# ./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-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
有可能的報錯
報錯1：
./configure: error: the HTTP XSLT module requires the libxml2/libxslt
libraries. You can either do not enable the module or install the libraries.
原因：缺少依賴
解決：
[root@vm-3 nginx-1.16.1]# yum -y install libxml2 libxslt-devel
再次配置
報錯2：
./configure: error: the HTTP image filter module requires the GD library.
You can either do not enable the module or install the libraries.
解決：安裝依賴
yum -y install gd-devel
再次配置
報錯3：
./configure: error: perl module ExtUtils::Embed is required
解決：
yum -y install perl-devel perl-ExtUtils-Embed
再次配置
報錯4：
./configure: error: the GeoIP module requires the GeoIP library. You can either do not enable the module or install the library.
解決：
yum -y install GeoIP GeoIP-devel GeoIP-data
再次配置
報錯5：
./configure: error: the Google perftools module requires the Google perftools
library. You can either do not enable the module or install the library.
解決：
yum install gperftools**
再次配置成功
三、make千萬不要make install
四、備份原 nginx 二進制文件
備份二進制文件和 nginx 的配置文件（期間nginx不會停止服務）
[root@vm-3 nginx-1.16.1]# mv /usr/sbin/nginx /usr/sbin/nginx_$(date %F)
五、復制新的nginx二進制文件，進入新的nginx源碼包
[root@vm-3 nginx-1.16.1]# cp /root/nginx-1.16.1/objs/nginx /usr/sbin/
六、測試新版本的nginx是否正常
[root@vm-3 nginx-1.16.1]# nginx -t
報錯：
nginx: [emerg] module "/usr/lib64/nginx/modules/ngx_http_geoip_module.so" version 1012002 instead of 1016001 in /usr/share/nginx/modules/mod-http-geoip.conf:1
nginx: configuration file /etc/nginx/nginx.conf test failed
解決：
vim /etc/nginx/nginx.conf //進入配置文件中
注釋 #include /usr/share/nginx/modules/*.conf;
再次檢測成功
七、給nginx發送平滑遷移信號（若不清楚pid路徑，請查看nginx配置文件或find / -name \\\’nginx.pid\\\’ 查找）
[root@vm-3 nginx-1.16.1]# kill -USR2 cat /run/nginx.pid
八、查看nginx pid，會出現一個nginx.pid.oldbin
[root@vm-3 nginx-1.16.1]# ll /run/nginx*
-rw-r–r– 1 root root 5 Sep 6 00:36 /run/nginx.pid
-rw-r–r– 1 root root 6 Sep 6 00:00 /run/nginx.pid.oldbin
九、從容關閉舊的Nginx進程
[root@vm-3 nginx-1.16.1]# kill -WINCH cat /run/nginx.pid.oldbin
十、此時不重載配置啟動舊的工作進程
[root@vm-3 nginx-1.16.1]# kill -HUP cat /run/nginx.pid.oldbin
十一、結束工作進程，完成此次升級
[root@vm-3 nginx-1.16.1]# kill -QUIT cat /run/nginx.pid.oldbin
十二、驗證Nginx是否升級成功
[root@vm-3 nginx-1.16.1]# nginx -v
nginx version: nginx/1.16.1
升級成功
