gcc
1、查看gcc版本
gcc -v
2、gcc安装命令
yum -y install gcc
pcre和pcre-devel
nginx的http模块使用pcre来解析正则表达式
yum install -y pcre pcre-devel
zlib
nginx使用zlib对http包的内容进行gzip。
yum install -y zlib zlib-devel
openssl
openssl用于数据链路通信安全加密。
yum install -y openssl openssl-devel
安装nginx
1、去官网获取最新稳定版本下载链接,官网下载页面地址:http://nginx.org/en/download.html
2、在linux上,利用wget命令下载nginx
wget http://nginx.org/download/nginx-1.20.2.tar.gz
3、解压到你要存放的目标,我这里是放在/application。解压完毕,会看到对应的目录里面多出一个nginx-1.20.2的文件夹
tar -zxvf nginx-1.20.2.tar.gz -C /application[
4、切换到对应的解压目录,对nginx进行编译安装。按以下步骤执行命令](https://blog.csdn.net/lishuaipiao/article/details/116453998)
# 不需要https模块的, 这里只输入./configure即可
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
# 编译
make
# 安装
make install
5、启动nginx。当make install命令执行完,我们会看到/usr/local会多出一个nginx文件夹。我们切换到/usr/local/nginx/sbin,进行启动nginx。如果需要修改端口等其他配置信息,进入/usr/local/nginx/conf修改nginx.conf的里面的信息。
# 启动
./nginx -s start
# 刷新配置
./nginx -s reload
# 停止nginx
./nginx -s stop
# 查看nginx是否启动成功
ps -ef | grep nginx
配置nginx开机自启
1、在/etc/init.d下创建文件nginx,具体可参考官网的
https://www.nginx.com/resources/wiki/start/topics/examples/redhatnginxinit/
#!/bin/sh
#
# nginx - this script starts and stops the nginx daemon
#
# chkconfig: - 85 15

make_dirs() {

}

esac
2、赋值文件执行权限
chmod a+x /etc/init.d/nginx
3、将nginx服务加入chkconfig管理列表
chkconfig —add /etc/init.d/nginx
4、设置开机自启
chkconfig nginx on
5、其他操作命令
# 启动nginx
service nginx start
# 停止nginx
service nginx stop
# 重启nginx
service nginx restart
#查看nginx服务是否启动成功
ps -ef | grep nginx

location / {
proxy_pass http://127.0.0.1:8080/rocky/;
proxy_cookie_path /crazyandrew /;
client_max_body_size 1000m;

# http://locahost/image/demo1.jpg映射到/upload/image/demo1.jpg
location /image/ {
root /upload/image/;
rewrite ^/image/(.*)$ \$1 break;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
}
http和https共存
server {
listen 80 default backlog=2048;
listen 443 ssl;
server_name www.rocky.com;
root /web/rocky;
ssl_certificate 1_api.rocky.com_bundle.crt;
ssl_certificate_key 2_api.rocky.com.key;
}
游览器不能访问IP
执行ps aux | grep nginx,查看Nginx服务是否启动
执行netstat -ntlp,查看80端口是否分配给你Nginx
对80端口防火墙配置:firewall-cmd —zone=public —add-port=80/tcp —permanent
重启防火墙服务:systemctl restart firewalld.service
在服务器上执行 curl localhost 看是不是正常的,是正常的,就检查安全组(云服务器)、防火墙,selinux
