yum版nginx

备份现有的配置文件

yum安装的默认在/ect/nginx 目录，安全旗舰将整个目录备份到其它文件夹中。

yum安装版升级

查看nginx当前版本

当前的版本是1.20.1。

[root@localhost ~]# nginx -v
nginx version: nginx/1.20.1

将nginx升级到1.24版本

1，首先下载需要的rmp包 https://nginx.org/packages/centos/7/x86_64/RPMS/

2，将rpm包上传到服务器，进行本机安装。

rpm -ivh nginx-1.24.0-1.el7.ngx.x86_64.rpm

这里nginx-1.24.0-1.el7.ngx.x86_64.rpm需要指定具体路径。

可能出现文件冲突的错误：

[root@localhost ~]# rpm -ivh nginx-1.24.0-1.el7.ngx.x86_64.rpm
Preparing...                          ################################# [100%]

解决：

首先，卸载原来的版本，根据冲突提示是nginx-1:1.20.1-1.el7.ngx.x86_64这个rpm包，或者使用 rpm -qa | grep nginx查看rpm包。

root@localhost ~]# rpm -qa | grep nginx
nginx-1.20.1-1.el7.ngx.x86_64

卸载1.20.1 rpm包 rpm -e nginx-1:1.20.1-1.el7.ngx.x86_64 --nodeps，--nodeps 忽略依赖关系检查，允许在不考虑依赖的情况下强行卸载软件包。这个操作本身不会直接修改Nginx的配置文件。

再次执行rpm -ivh nginx-1.24.0-1.el7.ngx.x86_64.rpm,看到已经成功升级到了1.24版本。

[root@localhost ~]# rpm -ivh nginx-1.24.0-1.el7.ngx.x86_64.rpm

[root@localhost ~]# nginx -v
nginx version: nginx/1.24.0

重启服务：

systemctl restart nginx

如何将版本回退

首先卸载当前的rpm包，查看rpm包 rpm -qa | grep nginx

[root@localhost ~]# rpm -qa | grep nginx
nginx-1.24.0-1.el7.ngx.x86_64

卸载：rpm -e nginx-1:1.20.1-1.el7.ngx.x86_64 --nodeps

yum重新安装，可以指定版本。我的仓库是官方最新版所以安装完是1.26版本了，安装时指定1.20就是1.20版本了。

编译安装nginx

安装包下载地址

https://nginx.org/en/download.html

安装编译文件库

yum -y install make zlib zlib-devel gcc-c++ libtool  openssl openssl-devel

安装 PCRE

wget http://downloads.sourceforge.net/project/pcre/pcre/8.35/pcre-8.35.tar.gz
 tar zxvf pcre-8.35.tar.gz
 cd pcre-8.35
 ./configure
 make && make install
 pcre-config --version

安装NGINX

进入到NGINX解压目录

./configure --prefix=/usr/local/nginx --with-http_ssl_module --with-http_stub_status_module --with-pcre

make
make install

启动NGINX

/usr/local/nginx/sbin/nginx

版本升级

安装包上传编译

tar -zxvf nginx-1.24.0.tar.gz
cd nginx-1.24.0/
./configure --prefix=/tmp/nginx --with-http_ssl_module --with-http_stub_status_module --with-pcre 
make
make install

替换旧版本

将新编译的NGINX /tmp/nginx/sbin/nginx拷贝到 /usr/local/nginx/sbin/目录下替换掉之前编辑的nginx,替换前先将老的备份。

[root@localhost sbin]# ./nginx -v
nginx version: nginx/1.24.0

可以看到已经替换为新版本，重启启动NGINX即可。
