yum安裝nginx-1.12.2 升級到nginx-1.16.1
一、查看現有的 nginx 編譯參數
[root@vm-3 ~]# nginx -V
nginx version: nginx/1.12.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017
TLS SNI support enabled
configure arguments: --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/clientbody --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-httpauthrequestmodule --with-httpsslmodule --with-httpv2module --with-httprealipmodule --with-httpadditionmodule --with-httpxsltmodule=dynamic --with-httpimagefiltermodule=dynamic --with-httpgeoipmodule=dynamic --with-httpsubmodule --with-httpdavmodule --with-httpflvmodule --with-httpmp4module --with-httpgunzipmodule --with-httpgzipstaticmodule --with-httprandomindexmodule --with-httpsecurelinkmodule --with-httpdegradationmodule --with-httpslicemodule --with-httpstubstatusmodule --with-httpperlmodule=dynamic --with-mail=dynamic --with-mailsslmodule --with-pcre --with-pcre-jit --with-stream=dynamic --with-streamsslmodule --with-googleperftoolsmodule --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'
二、將上面加粗字體部分進行配置，加粗字體後面爲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，配置之後就不會出現下面這些錯誤了
yum -y install 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、複製新的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
註釋 #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、此時不重載配置啓動舊的工作進程
[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
