nginx由0.8.54无缝升级0.9.5 | nginx自动更新脚本

正好有一台测试机
试试nginx升级
原来版本是nginx0.8.54

下载最新版的nginx
#wget http://nginx.org/download/nginx-0.9.5.tar.gz
解压缩
#tar vxzf nginx-0.9.5.tar.gz
新版本编译
root@debian:~/nginx-0.9.5# cd nginx-0.9.5/
root@debian:~/nginx-0.9.5# ./configure
root@debian:~/nginx-0.9.5# make
make -f objs/Makefile
make[1]: Entering directory `/root/nginx-0.9.5′
gcc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Wunused-function -Wunused-variable -Wunused-value -Werror -g -I src/core -I src/event -I src/event/modules -I src/os/unix -I objs \……………………中间省略………………………………………….
make[1]: Leaving directory `/root/nginx-0.9.5′
make -f objs/Makefile manpage
make[1]: Entering directory `/root/nginx-0.9.5′
sed -e “s|%%PREFIX%%|/usr/local/nginx|” \

-e “s|%%ERROR_LOG_PATH%%|/usr/local/nginx/logs/error.log|” \
< man/nginx.8 > objs/nginx.8
make[1]: Leaving directory `/root/nginx-0.9.5′
编译完成

开始升级

root@debian:~/nginx-0.9.5# mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.old

关键 拷贝objs下的nginx

root@debian:~/nginx-0.9.5# cp objs/nginx /usr/local/nginx/sbin/

关键 升级

root@debian:~/nginx-0.9.5# make upgrade
/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
kill -USR2 `cat /usr/local/nginx/logs/nginx.pid`
sleep 1
test -f /usr/local/nginx/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx/logs/nginx.pid.oldbin`

查看版本

root@debian:~/nginx-0.9.5# /usr/local/nginx/sbin/nginx -v
nginx: nginx version: nginx/0.9.5

确实是无缝升级的，中间没有停顿
