本地调试proxysql

1. 构建镜像

Dockerfile + 构建镜像

FROM centos:7

LABEL description="Container for dev & debug"

# 安装依赖
RUN yum install -y automake bzip2 cmake make gcc-c++ gcc git openssl openssl-devel gnutls gnutls-devel libtool patch openssh-server perl-IPC-Cmd
RUN yum install -y gdb-gdbserver which 

# 配置ssh服务
RUN echo 'PermitRootLogin yes' >> /etc/ssh/sshd_config && \
    echo 'PermitEmptyPasswords yes' >> /etc/ssh/sshd_config && \
    echo 'PasswordAuthentication yes' >> /etc/ssh/sshd_config && \
    echo 'root:root' | chpasswd && \
    ssh-keygen -A

EXPOSE 22 
CMD ["/usr/sbin/sshd", "-D"]

docker build -t proxysqldebug:v1 .

2. 运行容器

docker run -d -p 2222:22 --security-opt seccomp:unconfined -v $PWD:/home/luzhangting001/proxysql --name proxysqldev proxysqldebug:v1

# 后面容器stop + start 不要在重启，如下图

3. 启动debug

配置launch.json

"configurations": [
    {
        "name": "(gdb) Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "/home/luzhangting001/proxysql/src/proxysql",
        "args": [
            "--foreground",
            "--debug",
            "--config",
            "/home/luzhangting001/proxysql/src/proxysql.cfg",
            "--initial"
        ],
        "stopAtEntry": true,
        "cwd": "/home/luzhangting001/proxysql",
        "pipeTransport": {
            "debuggerPath": "/usr/bin/gdb",
            "pipeProgram": "/usr/bin/ssh",
            "pipeArgs": [
                "root@localhost",
                "-p",
                "2222"
            ],
            "pipeCwd": ""
        },
        "environment": [],
        "externalConsole": true,
        "MIMode": "gdb",
        "sourceFileMap": {
            "/home/luzhangting001/proxysql": "${workspaceFolder}"
        }
    }
]

启动报错：因为之前弄过，ssh报错了

将known_hosts里面的相关信息删除, 其实我不知道是不是必须这么做，可能不是必须的

将本机的公钥上传

ssh-copy-id -p 2222 root@localhost

vscode里面启动
