Nginx平滑升级记录

一、具体的升级步骤

(1)升级和安装nginx第三方模块一样,需要查看原来安装nginx的版本以及编译的参数

[root@ittestserver1 opt]# /usr/local/nginx2/sbin/nginx -V
nginx version: nginx/1.10.3
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)
built with OpenSSL 1.1.0e 16 Feb 2017
TLS SNI support enabled
configure arguments: --prefix=/usr/local/nginx2 --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_stub_status_module --with-http_v2_module --with-openssl=/tmp/install/openssl-1.1.0e --with-http_v2_module

(2)下载要升级的nginx版本

(3)解压ningx下载的压缩包编译make,切记不要make install。

[root@ittestserver1 nginx-1.12.1]# make

由于make的时间比较长,需要稍等下。

(4)make编译完后会在安装目录下生成一个objs目录且在该目录下有一个nginx执行文件。

(5)备份原来老的nginx文件

[root@ittestserver1 nginx-1.12.1]# mv /usr/local/nginx2/sbin/nginx /usr/local/nginx2/sbin/nginx.bak
[root@ittestserver1 nginx-1.12.1]# cp objs/nginx /usr/local/nginx2/sbin/
[root@ittestserver1 nginx-1.12.1]# /usr/local/nginx2/sbin/nginx -t
nginx: the configuration file /usr/local/nginx2/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx2/conf/nginx.conf test is successful

(6)使用make upgrade替换老的nginx进程

[root@ittestserver1 nginx-1.12.1]# make upgrade

/usr/local/nginx2/sbin/nginx -t

nginx: configuration file /usr/local/nginx2/conf/nginx.conf test is successful
kill -USR2 `cat /usr/local/nginx2/logs/nginx.pid`
sleep 1
test -f /usr/local/nginx2/logs/nginx.pid.oldbin
kill -QUIT `cat /usr/local/nginx2/logs/nginx.pid.oldbin`

(7)执行/usr/local/nginx2/sbin/nginx -V查看nginx最新的版本及编译的参数

至此升级完成。
