Nginx平滑升级

环境准备

• 准备已经安装好的nginx-1.6.3版本，另需nginx-1.10.3的安装包

[root@nginx application]# ll
总用量 896
-rw-r--r--  1 root root 911509 1月  31 2017 nginx-1.10.3.tar.gz
drwxr-xr-x 16 1001 1001   4096 4月  25 13:38 nginx-1.6.3

查看nginx-1.6.3

[root@nginx application]# /application/nginx-1.6.3/sbin/nginx -V
nginx version: nginx/1.6.3
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-18) (GCC) 
configure arguments: --prefix=/application/nginx-1.6.3 --conf-path=/application/nginx-1.6.3/nginx.conf --user=www --group=www --with-http_stub_status_module

安装nginx-1.10.3

tar xf nginx-1.10.3.tar.gz && cd nginx-1.10.3
./configure --prefix=/application/nginx-1.10.3 --conf-path=/application/nginx-1.10.3/nginx.conf --user=www --group=www --with-http_stub_status_module  --with-http_ssl_module
make && make install

• 为了验证是否升级成功，将修改nginx-1.10.3主页文件

echo 'hello'>/application/nginx-1.10.3/html/index.html

对旧版本的nginx启动文件进行备份,并将新的启动文件复制过来

mv /application/nginx-1.6.3/sbin/nginx /application/nginx-1.6.3/sbin/nginx.old
 mv /application/nginx-1.10.3/objs/nginx /application/nginx-1.6.3/sbin/

进行平滑升级操作

[root@nginx application]# ps -aux|grep nginx

[root@nginx nginx-1.10.3]# kill -QUIT `cat /application/nginx-1.6.3/logs/nginx.pid.oldbin`
