Nginx

为nginx创建一个不登陆的用户

应该需要手动创建nginx属主和nginx属组。

groupadd nginx

useradd nginx -g nginx -s /sbin/nologin -M

编译的时候，指定执行的用户主和用户组

下载源码

wget http://nginx.org/download/nginx-1.21.6.tar.gz

开启tcp fast open需要在–with-cc-opt=里加入-DTCP_FASTOPEN=23

./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib/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 --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-g -O2 -fdebug-prefix-map=/data/builder/debuild/nginx-1.20.2/debian/debuild-base/nginx-1.20.2=. -DTCP_FASTOPEN=23 -fstack-protector-strong -Wformat -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -fPIC' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro -Wl,-z,now -Wl,--as-needed -pie'

nginx编译安装完成以后，修改nginx.conf

user nginx nginx;

授权nginx用户

没有则创建

sudo chown -R nginx:nginx /var/cache/nginx/

执行

sudo nginx -c /opt/nginx-1.22.0/conf/nginx.conf

验证
ps aux | grep nginx

Git

~/.ssh/config没有则新建，

加入内容：

Host github.com
  IdentityFile ~/.ssh/github_rsa
