墨香年少 32 发布于 2023年2月8日 使用g++命令，将c++文件生成执行文件后，如何部署上去 1. 生成执行文件 g++ test.cpp -o test -I/server/cgi/include -L/server/cgi/lib -lfastcgipp -lboost_system -lboost_thread -lpthread 2. 复制文件到nginx的cgi-bin目录 cp ./test /usr/local/nginx/cgi-bin/ 3. 找到原来的进程，杀死 netstat -lntp 比如，进程号是1234 kill -9 1234 这样原来的进程就被杀死了 4. 启动新的进程 spawn-fcgi -a 127.0.0.1 -p 7001 -f /usr/local/nginx/cgi-bin/test a是address 地址 p是port 端口 f是文件 不过一般还会跟上一个大写的P参数来制定一个pid的位置，这样杀死已有进程的时候，就不需要去查找进程id了，直接杀死进程位置的文件就可以了 目之所及，皆是回忆，心之所想，皆是过往 分享这篇帖子 链接帖子 分享到其他站点
墨香年少 32 发布于 2023年2月8日 也可以加上如下命令使用c++11标准库 g++ test.cpp -o test -I/server/cgi/include -L/server/cgi/lib -lfastcgipp -lboost_system -lboost_thread -lpthread -std=c++11 目之所及，皆是回忆，心之所想，皆是过往 分享这篇帖子 链接帖子 分享到其他站点
