Nginx负载均衡健康检查性能提升
作者:ChengKe_dawn
前言
在Nginx官方模块提供的模块中,没有对负载均衡后端节点的健康检查模块 但可以使用第三方模块 nginx_upstream_check_module 来检测后端服务器的健康状态。我安装Nginx的方式,是通过 yum 安装的,通过 yum 安装的没有 nginx_upstream_check_module 这个模块,所以我们需要先给 Nginx 把这个模块安装好。
如果你已经yum安装过Nginx,那么建议最好是先 yum remove nginx 卸载一下,暂时没有找到找能不卸载然后给Nginx配置这个模块的办法。
安装配置
- 安装依赖包
yum -y install gcc glibc gcc-c++ openssl-devel pcre-devel patch
- 下载nginx源码包和nginx_upstream_check模块第三方模块
cd /usr/local wget https://nginx.org/download/nginx-1.21.4.tar.gz wget https://github.com/yaoweibin/nginx_upstream_check_module/archive/refs/heads/master.zip
该第三方模块在 github 上的地址为:可以去查看,也给出了配置的示例,很详细。地址
- 解压Nginx源码包和第三方模块
tar -zxvf nginx-1.21.4.tar.gz unzip nginx_upstream_check_module-master.zip
添加Nginx模块
cd nginx-1.21.4/ patch -p1 < ../nginx_upstream_check_module-master/check_1.20.1+.patch
p1代表在Nginx目录,p0是不在Nginx目录
- 编译Nginx,需要添加upstream_check第三方模块
通过 nginx -V 查看
将以上内容复制下来
重新编译的时候加上 --add-module=/usr/local/nginx_patch/nginx_upstream_check_module-master。 模块地址就是你下载 nginx_upstream_check_module 到本地的地址。(但是有时候nginx -v会失败,但是不会又太大影响,直接复制下面的命令也是可以的)
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --add-module=/usr/local/nginx_patch/nginx_upstream_check_module-master --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie'
- 编译安装
make && make install
- 启动NGINX(防止因为报错为启动成功)
suho /usr/sbin/nginx
此时可能会报错没有发现某个文件夹,但是不影响,你去对应的目录创建一个即可
nginx -t 检查nginx配置是否正确
nginx -s reload 重新加载配置文件
博主的nginx.conf配置(其实建议最好的每个站点的配置文件独立开,但是我偷懒了并没有)
注意,这配置文件通用性比较高,但是也是需要依赖自己的需求修改部分配置,博主是在两台服务器之间进行搭建的两台NGINX,双方进行心跳检测,ip为内网和弹性两个,10.75.25.207对应的内网是10.75.28.14
