centos7安装nginx

第一步安装环境依赖

zlib 适用于数据压缩的函式库

[root@localhost ~]# yum install gcc-c++ -y

[root@localhost ~]# yum install pcre pcre-devel -y

[root@localhost ~]# yum install zlib zlib-devel -y

[root@localhost ~]# yum install openssl openssl-devel -y

第二步下载nginx安装包

[root@localhost local]# wget http://nginx.org/download/nginx-1.17.7.tar.gz

解压

[root@localhost local]# tar -zxvf nginx-1.17.7.tar.gz

删除压缩包

[root@localhost local]# rm -rf nginx-1.17.7.tar.gz

进入nginx

[root@localhost local]# cd nginx-1.17.7

这里需要了解ssl，需不需要配置

如果不配置直接

[root@localhost nginx-1.17.7]# ./configure

1.不需要SSL

./configure --prefix=/usr/local/nginx
2.需要SSL

./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
编译安装

make

make install

 

查找安装路径

[root@localhost nginx-1.17.7]# whereis nginx
nginx: /usr/local/nginx

 启动

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

# 重启

/usr/local/nginx/sbin/nginx -s reload

查看nginx运行进程状态

netstat -anptu | grep nginx

设置开机启动

.即在rc.local增加启动代码就可以了
vim /etc/rc.local
增加一行 /usr/local/nginx/sbin/nginx
设置开机自启

vi /lib/systemd/system/nginx.service

#nginx.service内添加以下内容：

Description=nginx - high performance web server
After=network.target remote-fs.target nss-lookup.target
[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
[Install]
WantedBy=multi-user.target

按下esc  然后:wq

#使配置生效

systemctl daemon-reload

#设置开机启动

systemctl enable nginx.service

备注：如果不能访问：需检查服务器的防火墙是否打开，80端口是否对外开放：

查看开放的端口号：firewall-cmd --list-all

设置开放的端口号：firewall-cmd --add-service=http –permanent

firewall-cmd --add-port=80/tcp --permanent

重启防火墙：firewall-cmd –reload

防火墙设置完成后，在浏览器输入服务器ip+80端口访问：
