linux centos7 实现yum安装的nginx平滑升级 从1.12.2版本到1.16.1版本

yum安装nginx-1.12.2 升级到nginx-1.16.1

一、查看现有的 nginx 编译参数
[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、将上面加粗字体部分进行配置，加粗字体后面为系统的配置文件不需要配置，只需要到 make，千万不要 make install 。如果make install 会将原来的配置文件覆盖

事先可以先把这些依赖包下好，配置之后就不会出现下面这些错误了
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
准备新版本的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

有可能的报错
报错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：缺少依赖
解决：
[root@vm-3 nginx-1.16.1]# yum -y install libxml2 libxslt-devel

再次配置
报错2：
./configure: error: the HTTP image filter module requires the GD library.
You can either do not enable the module or install the libraries.
解决：安装依赖
yum -y install gd-devel

再次配置
报错3：
./configure: error: perl module ExtUtils::Embed is required
解决：
yum -y install perl-devel perl-ExtUtils-Embed
再次配置
报错4：
./configure: error: the GeoIP module requires the GeoIP library. You can either do not enable the module or install the library.
解决：
yum -y install GeoIP GeoIP-devel GeoIP-data
再次配置
报错5：
./configure: error: the Google perftools module requires the Google perftools
library. You can either do not enable the module or install the library.
解决：
yum install gperftools**
再次配置成功

三、make千万不要make install

四、备份原 nginx 二进制文件
备份二进制文件和 nginx 的配置文件（期间nginx不会停止服务）
[root@vm-3 nginx-1.16.1]# mv /usr/sbin/nginx /usr/sbin/nginx_$(date +%F)

五、复制新的nginx二进制文件，进入新的nginx源码包
[root@vm-3 nginx-1.16.1]# cp /root/nginx-1.16.1/objs/nginx /usr/sbin/

六、测试新版本的nginx是否正常
[root@vm-3 nginx-1.16.1]# nginx -t
报错：
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
解决：
vim /etc/nginx/nginx.conf //进入配置文件中
注释 #include /usr/share/nginx/modules/*.conf;
再次检测成功

七、给nginx发送平滑迁移信号（若不清楚pid路径，请查看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，会出现一个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、从容关闭旧的Nginx进程
[root@vm-3 nginx-1.16.1]# kill -WINCH cat /run/nginx.pid.oldbin

十、此时不重载配置启动旧的工作进程
[root@vm-3 nginx-1.16.1]# kill -HUP cat /run/nginx.pid.oldbin

十一、结束工作进程，完成此次升级
[root@vm-3 nginx-1.16.1]# kill -QUIT cat /run/nginx.pid.oldbin

十二、验证Nginx是否升级成功
[root@vm-3 nginx-1.16.1]# nginx -v
nginx version: nginx/1.16.1
升级成功
