2.6 设置Nginx环境变量
修改
/etc/profile配置文件添加$NGINX_HOME环境变量[root@other-server ]$ vim /etc/profile [root@other-server ]$ cat /etc/profile export NGINX_HOME="/usr/local/nginx" export PATH=$PATH:$NGINX_HOME/sbin [root@other-server ]$ source /etc/profile # 刷新/etc/profile配置文件测试nginx环境变量是否生效，查看nginx版本信息
[root@other-server opt]$ nginx -v nginx version: nginx/1.25.2将nginx/conf配置文件软链接到/etc/nginx目录中
创建/etc/nginx目录
[root@other-server opt]$ mkdir -p /etc/nginx创建软链接
[root@other-server opt]$ ln -s /usr/local/nginx/conf /etc/nginx/conf查看创建状态
[root@other-server nginx]$ pwd /etc/nginx [root@other-server nginx]$ ll total 0 lrwxrwxrwx 1 root root 22 Aug 30 22:01 conf -> /usr/local/nginx/conf/ # 补充：删除软链接：unlink nginx
2.7 创建nginx.service使用systemctl管理
创建/usr/lib/systemd/system/nginx.service配置文件，使用systemctl管理Nginx服务
[root@OtherServer opt]$ cat /usr/lib/systemd/system/nginx.service
[Unit]

3 创建NginxUDP/TCP协议转发配置文件
3.1 nginx.conf
stream nginx.conf主配置文件,加载514.conf配置文件。
stream { # 需要与http同一级
log_format basic 'time=[$time_local] remote_addr=$remote_addr ' # 设置basic日志格式
'protocol=$protocol '
'status=$status '
'bytes_sent=$bytes_sent '
'bytes_received=$bytes_received '
'session_time=$session_time'
include /usr/local/nginx/conf/stream/*.conf; # 加载udp.d目录下的配置文件
}
3.2 514.conf
514 端口转发配置文件[负载均衡]
upstream udp_514_server {
# 希负载均衡策略可以通过客户端 IP（$remote_addr）实现简单的会话保持，其可将同一IP客户端始终转发给同一台后端服务器。
hash $remote_addr;
server 10.10.0.102:514 weight=5;
server 10.10.0.103:514 weight=5;
# weight 权重值
# udp不建议添加<max_fails>和<fail_timeout>参数
}
upstream tcp_514_server {
# 希负载均衡策略可以通过客户端 IP（$remote_addr）实现简单的会话保持，其可将同一IP客户端始终转发给同一台后端服务器。
hash $remote_addr;
server 10.10.0.102:514 weight=5 max_fails=3 fail_timeout=30s;
server 10.10.0.103:514 weight=5 max_fails=3 fail_timeout=30s;
# weight 权重值
# max_fails：在服务器被标记为不可用的时间内必须发生的失败尝试次数（默认为1次尝试）
# fail_timeout：多次尝试失败而将服务器标记为不可用的时间，以及将服务器标记为不可用的时间（默认为10秒）
# udp不建议添加<max_fails>和<fail_timeout>参数
}
# udp 514 端口代理
server {
listen 514 udp; # 监听udp 514端口
proxy_timeout 1s; # 获取被代理服务器的响应最大超时时间为1s
proxy_connect_timeout 1s; # 与被代理服务器建立连接的超时时间为1s
access_log /var/log/nginx/udp_514_server.log basic;
error_log /var/log/nginx/udp_error_514_server.log;
proxy_pass udp_514_server; # 代理upstream名称
}
# tcp 514 端口代理
server {
listen 514; # 监听tcp 514端口
proxy_timeout 1s; # 获取被代理服务器的响应最大超时时间为1s
proxy_connect_timeout 1s; # 与被代理服务器建立连接的超时时间为1s
proxy_next_upstream on; # 当被代理的服务器返回错误或超时时，将未返回响应的客户端连接请求传递给upstream中的下一个服务器
proxy_next_upstream_tries 3; # 转发尝试请求最多3次
proxy_next_upstream_timeout 10s; # 总尝试超时时间为10s
proxy_socket_keepalive on; # 开启SO_KEEPALIVE选项进行心跳检测
access_log /var/log/nginx/tcp_514_server.log basic;
error_log /var/log/nginx/tcp_error_514_server.log;
proxy_pass tcp_514_server; # 代理upstream名称
}
3.3 启动nginx服务使配置生效
