C語言可以通過SSH連接MySQL數據庫,下面是實現的具體步驟:
1. 安裝必要的軟件。
sudo apt-get install build-essential gcc zlib1g-dev libssl-dev libssh2-1-dev libmysqlclient-dev
2. 導入MySQL客戶端庫。
mysql_config --cflags mysql_config --libs
復制這兩個命令的輸出結果,并將其用于鏈接MySQL客戶端庫的命令中。
3. 使用libssh庫開發SSH客戶端。
#include <libssh/libssh.h> int main() { ssh_session my_ssh_session; int rc; char *password; my_ssh_session=ssh_new(); ssh_options_set(my_ssh_session, SSH_OPTIONS_HOST, "remote_hostname"); ssh_options_set(my_ssh_session, SSH_OPTIONS_USER, "username"); rc=ssh_connect(my_ssh_session); password=getpass("Password: "); ssh_options_set(my_ssh_session, SSH_OPTIONS_PASSWORD, password); rc=ssh_userauth_password(my_ssh_session, NULL, password); ssh_channel channel; channel = ssh_channel_new(my_ssh_session); rc = ssh_channel_open_session(channel); ssh_channel_request_exec(channel, "mysql -u [username] -p[password] -h [hostname] [databasename] -e [sql_query]"); ssh_channel_send_eof(channel); ssh_channel_close(channel); ssh_channel_free(channel); ssh_disconnect(my_ssh_session); ssh_free(my_ssh_session); return 0; }
通過上述步驟,可以通過SSH連接MySQL數據庫,并實現需要的操作。
