前置工作:
安装必要的库（Nginx 中gzip模块需要 zlib 库，rewrite模块需要 pcre 库，ssl 功能需要openssl库）
ps:我的centos7自带就有上面的三个库,安装前可以用rpm命令检查一下看是否已经安装过
[root@mylsql local]# rpm -q pcre pcre-8.32-15.el7_2.1.x86_64 [root@mylsql local]# rpm -q openssl openssl-1.0.1e-60.el7.x86_64 [root@mylsql local]# rpm -q zlib zlib-1.2.7-17.el7.x86_64
step1:
先执行下面的命令创建这个文件
vim /etc/yum.repos.d/Nginx.repo
step2:
输入下面的内容
[Nginx] name=Nginx repo baseurl=http://Nginx.org/packages/centos/7/$basearch/ #如果是centos6.x的则只需要将baseurl的值修改为http://Nginx.org/packages/centos/6/$basearch/ gpgcheck=0 enabled=1
step3:
执行安装命令
yum install Nginx -y
注意:
可能会出现如下图的错误
直接执行命令
rm -f /var/run/yum.pid
然后再执行上面的安装命令就可以了:执行成功会如下结果

成功之后运行Nginx
systemctl start Nginx
记得查看下80端口是否已经打开
firewall-cmd --zone=public --list-port
结果如下
如果没有开启端口则需要添加端口
[root@mylsql local]# firewall-cmd --zone=public --add-port=80/tcp --permanent success [root@mylsql local]# firewall-cmd --reload success
端口开启了,Nginx也运行了,接下来可以访问这台服务器的ip了
安装到此结束:
过程错误总结:
由于我们公司有专门的运维人员,所以操作系统,服务器系统都不需要我们自己装;然后我没先确认一下操作系统的版本,centos7安装了centos6.5的Nginx出l了各种问题
查看版本的命令
