Nginx 平滑升级 安装实验(从0.7.56升级到.8.38)
实验开始：# groupadd -g 1024 www
# useradd -u 1024 -g nginx -M -s /sbin/nologin www
# /usr/local/nginx/sbin/nginx -V
nginx version: nginx/0.7.56
built by gcc 4.1.2 20080704 (Red Hat 4.1.2-46)
TLS SNI support disabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx/ --with-http_stub_status_module --with-http_ssl_module
1.下载nginx0.8.38
wget http://www.nginx.org/download/nginx-0.8.38.tar.gz
2.解压
tar zxvf nginx-0.8.38.tar.gz
3.进入nginx-0.8.38目录
cd nginx-0.8.38/
4.编译 ./configure –user=www –group=www –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module
make
5.备份nginx 原文件
mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old
6.复制编译make后的nginx二进制文件覆盖nginx旧版本二进制文件
cp objs/nginx /usr/local/nginx/sbin/nginx
7.测试nginx配置文件
/usr/local/nginx/sbin/nginx -t
the configuration file /usr/local/nginx//conf/nginx.conf syntax is ok
configuration file /usr/local/nginx//conf/nginx.conf test is successful
8.把nginx.pid 改成nginx.pid.oldbin，然后紧跟着启动新版本的nginx
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
9.退出旧版本的nginx
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`
10.查看新版本的nginx
lsof -i :80
COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME
nginx 15495 root 6u IPv4 12577 TCP *:http (LISTEN)
nginx 15496 www 6u IPv4 12577 TCP *:http (LISTEN)
ps -ef |grep nginx
root 15495 1 0 07:55 ? 00:00:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
www 15496 15495 0 07:55 ? 00:00:00 nginx: worker process
root 15521 11524 0 08:11 pts/0 00:00:00 grep nginx
/usr/local/nginx/sbin/nginx -v
nginx version: nginx/0.8.38
OK ,平滑升级完成！！
