在 RedHat/CentOS 中以服务形式运行二进制文件

我创建了一个脚本来将二进制文件作为服务执行。但该服务并未启动，而当我停止该服务时，它却显示多个 pid。

我正在使用 RHEL 7。以下是完整的详细信息

NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

通常我们按如下方式运行脚本./pipeline --config pipeline.conf

[Unit]
Description=Pipeline service

[Service]
Type=simple
User=cisco
ExecStart=/hfqp/bin/pipeline --config /hfqp/bin/pipeline.conf

并做了以下事情

systemctl daemon-reload
systemctl start pipeline.service

即使这样也无济于事。

这是错误日志

任何帮助表示感谢

您是否查看过以下错误信息？

Apr 16 06:29:32 matrix-pipeline-b-01 executePipeline.sh[10195]: sudo: no tty present and no askpass program specified
Apr 16 06:29:32 matrix-pipeline-b-01 sudo[10196]: pam_unix(sudo:auth): auth could not identify password for [cisco]

看起来 cisco 用户无法以 sudo 权限运行命令，因为这很可能是非交互式脚本。您可以通过编辑文件来授予无密码 sudo /etc/sudoers。

$ sudo visudo
# Add a line like this to /etc/sudoers
# username ALL = NOPASSWD: /fullpath/to/command, /fullpath/to/othercommand
cisco ALL = NOPASSWD: /hfqp/bin/pipeline --config /hfqp/bin/pipeline.conf
