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=1step3:
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
[root@mylsql local]# yum install nginx -y

完毕！
[root@mylsql local]#
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
[root@mylsql local]# cat /proc/version
Linux version 3.10.0-514.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-11) (GCC) ) #1 SMP Tue Nov 22 16:42:41 UTC 2016
查看nginx各个文件:
rpm -ql nginx这里包括nginx所有文件的位置
