nginx版本的平滑升级

 

   nginx版本的平滑升级

    前几天我同事晚上值班没事的时候，把公司客户的一些nginx服务器进行了升级，这种操作我还从来没有做过，也挺好奇的，今天闲来没事就在网上找了类似的文档，进行了操作，并把其过程记录了下来……

1.查看自己服务器nginx的版本和最早自己编译安装是的参数

[root@localhost ~]# /usr/local/nginx/sbin/nginx -V
 nginx version: nginx/1.2.1
 built by gcc 4.1.2 20080704 (Red Hat 4.1.2-46)
 TLS SNI support disabled
 configure arguments: --prefix=/usr/local --sbin-path=/usr/sbin/nginx \
 --conf-path=/usr/local/nginx/conf/nginx.conf \
 --error-log-path=/var/log/nginx/error.log \
 --http-log-path=/var/log/nginx/access.log \
 --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock \
 --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module \
 --with-http_stub_status_module --with-http_gzip_static_module \
 --http-client-body-temp-path=/var/tmp/nginx/client/ \
 --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
 --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
 --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
 --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre

2.在这里http://nginx.org/en/download.html找到最新的nginx版本，并下载到服务器上

3.对新版本进行解压并编译，其中安装目录必须和原来的一样，但是可以添加一些新的参数

[root@localhost ~]# tar xvf nginx-1.2.4.tar.gz
[root@localhost ~]# cd nginx-1.2.4
[root@localhost nginx-1.2.4]# ./configure --prefix=/usr/local \
  --sbin-path=/usr/sbin/nginx --conf-path=/usr/local/nginx/conf/nginx.conf \
  --error-log-path=/var/log/nginx/error.log \
  --http-log-path=/var/log/nginx/access.log \
  --pid-path=/var/run/nginx/nginx.pid --lock-path=/var/lock/nginx.lock \
  --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module \
  --with-http_stub_status_module --with-http_gzip_static_module \
  --http-client-body-temp-path=/var/tmp/nginx/client/ \
  --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
  --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
  --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
  --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre

4.只执行make命令，不需要make install

[root@localhost nginx-1.2.4]# make

5.替换nginx的一个二进制文件

[root@localhost nginx-1.2.4]# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
[root@localhost nginx-1.2.4]# cp objs/nginx /usr/local/nginx/sbin/

6.进行测试是否成功

[root@localhost nginx-1.2.4]# /usr/local/nginx/sbin/nginx -t
 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
 nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

7.执行命令进行平滑升级

[root@localhost nginx-1.2.4]# make upgrade
 /usr/sbin/nginx -t
 nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
 nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
 kill -USR2 `cat /var/run/nginx/nginx.pid`
 sleep 1
 test -f /var/run/nginx/nginx.pid.oldbin
 kill -QUIT `cat /var/run/nginx/nginx.pid.oldbin`

make upgrade执行命令后显示的信息，其实显示的就是都执行了哪几个命令，也可以自己手动执行那个kill命令

8.在次查看版本信息

[root@localhost nginx-1.2.4]# /usr/local/nginx/sbin/nginx -V
 nginx version: nginx/1.2.4
 built by gcc 4.1.2 20080704 (Red Hat 4.1.2-46)
 TLS SNI support disabled
 configure arguments: --prefix=/usr/local --sbin-path=/usr/sbin/nginx
 --conf-path=/usr/local/nginx/conf/nginx.conf \
 --error-log-path=/var/log/nginx/error.log \
 --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx/nginx.pid \
 --lock-path=/var/lock/nginx.lock --user=nginx --group=nginx \
 --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module \
 --with-http_gzip_static_module \
 --http-client-body-temp-path=/var/tmp/nginx/client/
 --http-proxy-temp-path=/var/tmp/nginx/proxy/ \
 --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
 --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
 --http-scgi-temp-path=/var/tmp/nginx/scgi --with-pcre

nginx升级完成！
