云野 LNMP架构-nginx编译安装/平滑升级
1. nginx源码编译安装
1.1 下载nginx安装包
wget http://nginx.org/download/nginx-1.22.0.tar.gz
1.2 下载nginx所需的依赖性
yum install -y gcc pcre-devel openssl-devel
1.3 解压下载的nginx安装包
[root@vm5 ~]# ls
nginx-1.22.0.tar.gz
[root@vm5 ~]# tar -zxvf nginx-1.22.0.tar.gz
nginx-1.22.0/
nginx-1.22.0/auto/
nginx-1.22.0/conf/
nginx-1.22.0/contrib/
nginx-1.22.0/src/
.......
1.4 编译nginx,三部曲
[root@vm5 ~]# ls
nginx-1.22.0 nginx-1.22.0.tar.gz
[root@vm5 ~]# cd nginx-1.22.0/
[root@vm5 nginx-1.22.0]# ls
auto CHANGES.ru configure html man src
CHANGES conf contrib LICENSE README
[root@vm5 nginx-1.22.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module
checking for OS
+ Linux 3.10.0-957.el7.x86_64 x86_64
checking for C compiler ... found
+ using GNU C compiler
......
[root@vm5 nginx-1.22.0]# make
make -f objs/Makefile
make[1]: Entering directory `/root/nginx-1.22.0'
cc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g -I src/core -I src/event -I src/event/modules -I src/os/unix -I objs
-o objs/src/core/nginx.o
.......
[root@vm5 nginx-1.22.0]# make install
make -f objs/Makefile install
make[1]: Entering directory `/root/nginx-1.22.0'
test -d '/usr/local/nginx' || mkdir -p '/usr/local/nginx'
test -d '/usr/local/nginx/sbin'
|| mkdir -p '/usr/local/nginx/sbin'
test ! -f '/usr/local/nginx/sbin/nginx'
|| mv '/usr/local/nginx/sbin/nginx'
.......
1.6 创建Nginx链接,启动nginx
[root@vm5 nginx-1.20.0]# ln -s /usr/local/nginx/sbin/nginx /usr/sbin/
[root@vm5 nginx-1.20.0]# nginx
1.5 访问主机ip,看是否可以可以访问到nginx的默认测试发布目录
[root@vm5 ~]# ip addr
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 52:54:00:ce:a8:b0 brd ff:ff:ff:ff:ff:ff
inet 172.25.32.5/24 brd 172.25.32.255 scope global noprefixroute eth0
valid_lft forever preferred_lft forever
inet6 fe80::5054:ff:fece:a8b0/64 scope link
valid_lft forever preferred_lft forever
[root@vm5 ~]# curl 172.25.32.5

2. nginx平滑升级
2.1 下载nginx新版本软件，正常执行./configure 和make 但不要执行make install
[root@vm5 ~]# wget http://nginx.org/download/nginx-1.20.0.tar.gz
[root@vm5 ~]# ls
nginx-1.20.0 nginx-1.20.0.tar.gz nginx-1.22.0.tar.gz
[root@vm5 ~]# tar zxvf nginx-1.22.0.tar.gz
nginx-1.22.0/
nginx-1.22.0/auto/
nginx-1.22.0/conf/
nginx-1.22.0/contrib/
......
[root@vm5 ~]# ls
nginx-1.20.0 nginx-1.20.0.tar.gz nginx-1.22.0 nginx-1.22.0.tar.gz
[root@vm5 ~]# cd nginx-1.22.0/
[root@vm5 nginx-1.22.0]# ls
auto CHANGES.ru configure html man src
CHANGES conf contrib LICENSE README
[root@vm5 nginx-1.22.0]# ./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module
checking for OS
+ Linux 3.10.0-957.el7.x86_64 x86_64
.....
[root@vm5 nginx-1.22.0]# make
make -f objs/Makefile
make[1]: Entering directory `/root/nginx-1.22.0'
cc -c -pipe -O -W -Wall -Wpointer-arith -Wno-unused-parameter -Werror -g -I src/core -I src/event -I src/event/modules -I src/os/unix -I objs
.....
2.2 备份原程序
[root@vm5 ~]# cd /usr/local/nginx/sbin/
[root@vm5 sbin]# cp nginx nginx.old
[root@vm5 sbin]# ls
nginx nginx.old
2.3 拷贝新程序
[root@vm5 ~]# cd nginx-1.22.0/
[root@vm5 nginx-1.22.0]# ls
auto CHANGES.ru configure html Makefile objs src
CHANGES conf contrib LICENSE man README
[root@vm5 nginx-1.22.0]# cd objs/
[root@vm5 objs]# ls
autoconf.err nginx ngx_auto_config.h ngx_modules.c src
Makefile nginx.8 ngx_auto_headers.h ngx_modules.o
[root@vm5 objs]# ./nginx -v
nginx version: nginx/1.22.0
[root@vm5 objs]# cp -f nginx /usr/local/nginx/sbin/nginx
2.4 获取当前nginx主进程pid
[root@vm5 objs]# ps ax|grep nginx
26380 ? Ss 0:00 nginx: master process nginx
26381 ? S 0:00 nginx: worker process
26411 pts/0 R+ 0:00 grep --color=auto nginx
2.5 升级新程序
[root@vm5 objs]# kill -USR2 26380
[root@vm5 objs]# ps ax|grep nginx
26380 ? Ss 0:00 nginx: master process nginx
26381 ? S 0:00 nginx: worker process
26412 ? S 0:00 nginx: master process nginx
26413 ? S 0:00 nginx: worker process
26415 pts/0 R+ 0:00 grep --color=auto nginx
2.6 关闭原worker进程但保留主进程：为了回退
[root@vm5 objs]# kill -WINCH 26380
2.7 访问nginx，查看nginx版本,已经由原来的1.20版本升级至1.22版本
[root@vm5 objs]# curl localhost -I
HTTP/1.1 200 OK
Server: nginx/1.22.0
Date: Thu, 14 Jul 2022 07:15:32 GMT
Content-Type: text/html
Content-Length: 612
Last-Modified: Thu, 14 Jul 2022 02:16:43 GMT
Connection: keep-alive
ETag: "62cf7c8b-264"
Accept-Ranges: bytes
3. nginx版本回退
3.1 还原nginx程序
[root@vm5 sbin]# cp -f nginx.old nginx
3.2 唤醒原进程
[root@vm5 sbin]# ps ax|grep nginx
26380 ? Ss 0:00 nginx: master process nginx
26412 ? S 0:00 nginx: master process nginx
26413 ? S 0:00 nginx: worker process
26436 pts/0 S+ 0:00 grep --color=auto nginx
[root@vm5 sbin]# kill -HUP 26380
3.3 回收新版本的worker进程
[root@vm5 sbin]# kill -WINCH 26413
3.4 关闭新版本主进程
[root@vm5 sbin]# kill -QUIT 26412
3.5 访问nginx，查看nginx版本,已经由原来的1.22版本升级至1.20版本
[root@vm5 sbin]# curl localhost -I
HTTP/1.1 200 OK
Server: nginx/1.20.0
Date: Thu, 14 Jul 2022 07:46:48 GMT
