nginx升级

1、源码包下载：http://nginx.org/en/download.html (nginx-1.20.2.tar.gz)

 

2、查看旧版本安装模块：nginx -V

nginx -V
nginx version: nginx/1.20.2
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/etc/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 --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --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-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

3、编译不安装

./configure --prefix=/etc/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 --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --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-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'

make
注：make后会生成一个objs文件夹

[root@ecs-20b8-0925717 nginx-1.20.2]# ls
auto CHANGES.ru configure html Makefile objs src
CHANGES conf contrib LICENSE man README

注：

nginx path prefix: "/etc/nginx"
nginx binary file: "/usr/sbin/nginx"
nginx modules path: "/usr/lib64/nginx/modules"
nginx configuration prefix: "/etc/nginx"
nginx configuration file: "/etc/nginx/nginx.conf"
nginx pid file: "/var/run/nginx.pid"
nginx error log file: "/var/log/nginx/error.log"
nginx http access log file: "/var/log/nginx/access.log"
nginx http client request body temporary files: "/var/cache/nginx/client_temp"
nginx http proxy temporary files: "/var/cache/nginx/proxy_temp"
nginx http fastcgi temporary files: "/var/cache/nginx/fastcgi_temp"
nginx http uwsgi temporary files: "/var/cache/nginx/uwsgi_temp"
nginx http scgi temporary files: "/var/cache/nginx/scgi_temp"

代表./configure执行成功，

objs/ngx_modules.o \
-Wl,-z,relro -Wl,-z,now -pie -ldl -lpthread -lpthread -lcrypt -lpcre -lssl -lcrypto -ldl -lpthread -lz \
-Wl,-E
sed -e "s|%%PREFIX%%|/etc/nginx|" \
-e "s|%%PID_PATH%%|/var/run/nginx.pid|" \
-e "s|%%CONF_PATH%%|/etc/nginx/nginx.conf|" \
-e "s|%%ERROR_LOG_PATH%%|/var/log/nginx/error.log|" \
< man/nginx.8 > objs/nginx.8
make[1]: Leaving directory `/usr/local/nginx-1.20.2'

代表make执行成功

4、查看安装需要的文件（找一台非正式环境的机器执行make install）

 make install
make -f objs/Makefile install
make[1]: Entering directory `/usr/local/nginx-1.20.2'
test -d '/etc/nginx' || mkdir -p '/etc/nginx'
test -d '/usr/sbin' \
        || mkdir -p '/usr/sbin'
test ! -f '/usr/sbin/nginx' \
        || mv '/usr/sbin/nginx' \
                '/usr/sbin/nginx.old'
cp objs/nginx '/usr/sbin/nginx'
test -d '/etc/nginx' \
        || mkdir -p '/etc/nginx'
cp conf/koi-win '/etc/nginx'
cp conf/koi-utf '/etc/nginx'
cp conf/win-utf '/etc/nginx'
test -f '/etc/nginx/mime.types' \
        || cp conf/mime.types '/etc/nginx'
cp conf/mime.types '/etc/nginx/mime.types.default'
test -f '/etc/nginx/fastcgi_params' \
        || cp conf/fastcgi_params '/etc/nginx'
cp conf/fastcgi_params \
        '/etc/nginx/fastcgi_params.default'
test -f '/etc/nginx/fastcgi.conf' \
        || cp conf/fastcgi.conf '/etc/nginx'
cp conf/fastcgi.conf '/etc/nginx/fastcgi.conf.default'
test -f '/etc/nginx/uwsgi_params' \
        || cp conf/uwsgi_params '/etc/nginx'
cp conf/uwsgi_params \
        '/etc/nginx/uwsgi_params.default'
test -f '/etc/nginx/scgi_params' \
        || cp conf/scgi_params '/etc/nginx'
cp conf/scgi_params \
        '/etc/nginx/scgi_params.default'
test -f '/etc/nginx/nginx.conf' \
        || cp conf/nginx.conf '/etc/nginx/nginx.conf'
cp conf/nginx.conf '/etc/nginx/nginx.conf.default'
test -d '/var/run' \
        || mkdir -p '/var/run'
test -d '/var/log/nginx' \
        || mkdir -p '/var/log/nginx'
test -d '/etc/nginx/html' \
        || cp -R html '/etc/nginx'
test -d '/var/log/nginx' \
        || mkdir -p '/var/log/nginx'
make[1]: Leaving directory `/usr/local/nginx-1.20.2'

5、结合上面的输出内容对比正式环境中nginx的配置文件缺省的文件，将配置文件替换（注意保留自己的配置项）

我只替换了二进制文件

mv /usr/sbin/nginx /usr/sbin/nginx.old
cp objs/nginx '/usr/sbin/nginx'

6、平滑升级

nginx -t(测试是否正常)
# 查看nginx 主进程号
ps -ef|grep nginx 
# 
kill -USR2 PID(旧)
# 发送WINCH信号给旧的主进程。然后，他的工作进程将从容关闭
kill -WINCH PID(旧)
# 删除旧主进程
kill -QUIT 旧主进程号

7、如果多台相同环境的nginx需要升级，只需要将nginx二进制文件传到对应的/usr/sbin/下，执行平滑升级过程就可以了
