Centos7 安装nginx

1、直接用yum 进行安装

yum install nginx

 

 安装完成后查看nginx 的版本

# 查看nginx版本
nginx -v

3、查看编译参数

nginx -V

 

 4、查看安装目录

rpm -ql nginx

rpm -ql nginx
/etc/logrotate.d/nginx
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
/etc/nginx/fastcgi_params
/etc/nginx/fastcgi_params.default
/etc/nginx/koi-utf
/etc/nginx/koi-win
/etc/nginx/mime.types
/etc/nginx/mime.types.default
/etc/nginx/nginx.conf
/etc/nginx/nginx.conf.default
/etc/nginx/scgi_params

5、修改nginx 的配置文件

 首先需要查看一下nginx 的目录结构

[root@localhost conf]# whereis nginx

nginx: /usr/sbin/nginx /usr/lib64/nginx /etc/nginx /usr/local/nginx /usr/share/nginx /usr/share/man/man3/nginx.3pm.gz /usr/share/man/man8/nginx.8.gz

 

 

 启动nginx

cd /usr/sbin

./nginx -s reload

如果发生如下错误

nginx: [error] open() "/run/nginx.pid" failed (2: No such file or directory)

　　

执行以下语句

/usr/sbin/nginx -c /etc/nginx/nginx.conf

再次启动

./nginx -s reload

确认是否启动成功

./sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

查看nginx 的进程

ps -ef|grep nginx

 

 

添加端口到 防火墙列表

firewall-cmd --permanent --add-port=8881/tcp

#重新加载
firewall-cmd --reload

 

 

 

外部访问

http://ip:port

 

 发现访问的界面与预想的不一致，差了好多资料才发现8881 是centos 系统的默认端口，所以需要换一个端口

编辑 nginx.conf  将端口号改为8888

执行 nginx -s reload

再次访问

 

 至此nginx 安装成功。

 http://10.10.185.111:8888/niginx.cn

如果不使用yum 安装需要注意的是不能将安装包放在 /usr/local/nginx 下否组会在make  install 时出现如下错误

[root@localhost nginx]# make install
make -f objs/Makefile install
make[1]: 进入目录“/usr/local/nginx”
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'                     '/usr/local/nginx/sbin/nginx.old'
cp objs/nginx '/usr/local/nginx/sbin/nginx'
test -d '/usr/local/nginx/conf'                 || mkdir -p '/usr/local/nginx/conf'
cp conf/koi-win '/usr/local/nginx/conf'
cp: "conf/koi-win" 与"/usr/local/nginx/conf/koi-win" 为同一文件
make[1]: *** [install] 错误 1
make[1]: 离开目录“/usr/local/nginx”
make: *** [install] 错误 2

　　个人的nginx 存放目录是 /home/nginx  对应的安装配置目录是/usr/local/nginx

 配置开机自启动

vi /etc/rc.d/rc.local

添加

/usr/local/nginx/sbin/nginx
