nginx平滑升级

#平滑升级

kill -USR2

 //查看nginx版本

1. [root@l1 logs]# nginx -v //查看nginx版本

2. nginx version: nginx/1.26.0

3. [root@l1 logs]#

安装一个1.25版本实验一下 

1. [root@l2 ~]# cd /opt/

2. [root@l2 opt]#

[root@l2 opt]# ls
 
nginx-1.25.5.tar.gz nginx-1.26.0.tar.gz rh

进行初始化配置 

[root@l2 opt]# systemctl disable --now firewalld.service
 
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
 
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
 
[root@l2 opt]# setenforce 0
 
[root@l2 opt]# vim /etc/selinux/config

安装软件包 

[root@l2 opt]# df

[root@l2 opt]# mount /dev/sr0 /mnt
 
mount: /dev/sr0 写保护，将以只读方式挂载
 
[root@l2 opt]# yum -y install pcre-devel zlib-devel openssl-devel gcc gcc-c++ make
 
//安装软件包 

创建用户  

[root@l2 opt]# useradd -M -s /sbin/nolongin nginx

 编译安装Nginx

[root@l2 opt]# cd /opt/
 
[root@l2 opt]# ls
 
nginx-1.25.5.tar.gz nginx-1.26.0.tar.gz rh
 
[root@l2 opt]# tar xf nginx-1.25.5.tar.gz //解压
 
[root@l2 opt]# cd nginx-1.25.5/
 
[root@l2 nginx-1.25.5]#

./configure \
 
--prefix=/usr/local/nginx \
 
--user=nginx \
 
--group=nginx \
 
--with-http_stub_status_module

 

[root@l2 nginx-1.25.5]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module --with-http_ssl_module
 
//指定安装路径，指定运行用户，运行组 ，开启模块，htps协议

[root@l2 nginx-1.25.5]# make && make install

 设置软链接，可以直接调用nginx命令来进行管理

[root@l2 nginx-1.25.5]# cd /usr/local/nginx/
 
[root@l2 nginx]# ls sbin/
 
nginx
 
[root@l2 nginx]# ln -s /usr/local/nginx/sbin/nginx /usr/local/sbin/
 
[root@l2 nginx]#
 
[root@l2 nginx]# /usr/local/nginx/sbin/nginx //运行
 
[root@l2 nginx]#
 
 
 
[root@l2 nginx]# cd /usr/lib/systemd/system
 
[root@l2 system]# vim nginx.service
 
[root@l2 system]#

[root@l2 system]# chmod 754 /lib/systemd/system/nginx.service
 
[root@l2 system]#

启动nginx服务 ​​​​​​​

/usr/local/nginx/sbin/nginx
 
 
netstat -lntp | grep 80

 查看pid进程号

1. [root@l2 ~]# cat /usr/local/nginx/logs/nginx.pid

2. 14039

3. [root@l2 ~]#

查看版本 

[root@l2 ~]# nginx -v
 
nginx version: nginx/1.25.5

[root@l2 ~]# netstat -lntp | grep 80
 
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 14039/nginx: master
 
//已在运行

tar -zxvf nginx-1.xx.xx.tar.gz 
cd nginx-1.xx.xx
./configure \
--prefix=/usr/local/nginx \
--user=nginx \
--group=nginx \
--with-http_stub_status_module

nginx文件做个替换

[root@l2 objs]# cd /usr/local/nginx/sbin/
 
[root@l2 sbin]# ls
 
nginx
 
[root@l2 sbin]# mv nginx nginx_old //做个备份
 
[root@l2 sbin]#
 
 
[root@l2 sbin]# cp /opt/nginx-1.26.0/objs/nginx ./
 
[root@l2 sbin]# ls
 
nginx nginx_old
 
[root@l2 sbin]#

•  注：
• mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx_old
•  cp objs/nginx /usr/local/nginx/sbin/nginx
• make upgrade  #要保证当前 nginx 进程是通过 /usr/local/nginx/sbin/nginx 启动的，而不是通过查找环境变量中那个 nginx 命令启动的
• #或者先 killall nginx ，再/usr/local/nginx/sbin/nginx
