狮身人面像安装centos7

Question

我刚刚在运行 centos 7 的专用服务器上将 sphinx 更新到最新版本，但经过数小时的搜索，我找不到问题。

狮身人面像索引创建良好，但我无法启动搜索守护进程。我一直收到这条消息：

systemctl status searchd.service
searchd.service - SphinxSearch Search Engine
Loaded: loaded (/usr/lib/systemd/system/searchd.service; disabled; vendor preset: disabled)
Active: failed (Result: timeout) since Sat 2018-03-24 21:14:09 CET; 3min 4s ago
Process: 17865 ExecStartPre=/bin/chown sphinx.sphinx /var/run/sphinx (code=exited, status=0/SUCCESS)
Process: 17863 ExecStartPre=/bin/mkdir -p /var/run/sphinx (code=killed, signal=TERM)

Mar 24 21:14:09  systemd[1]: Starting SphinxSearch Search Engine...
Mar 24 21:14:09  systemd[1]: searchd.service start-pre operation timed out. Terminating.
Mar 24 21:14:09  systemd[1]: Failed to start SphinxSearch Search Engine.
Mar 24 21:14:09  systemd[1]: Unit searchd.service entered failed state.
Mar 24 21:14:09  systemd[1]: searchd.service failed.

我真的不知道这个问题是从哪里来的。

在您的 systemd 服务文件中（我的在 /usr/lib/systemd/system/searchd.service 中）注释掉： /bin/chown sphinx.sphinx /var/run/sphinx /bin/mkdir -p /var/run/sphinx manually

（如果尚未完成，您可以手动运行这些命令）。

然后从 Type=forking 至 Type=simple

然后执行systemctl daemon-reload，您可以启动/停止/状态服务：

[root@server ~]# cat /usr/lib/systemd/system/searchd.service

Answer 2

我遇到了同样的问题，终于找到了适合我的解决方案。

我已经编辑了我的“/etc/systemd/system/sphinx.service”看起来像

[Unit]
Description=SphinxSearch Search Engine
After=network.target remote-fs.target nss-lookup.target
After=syslog.target

[Service]
User=sphinx
Group=sphinx
RuntimeDirectory=sphinxsearch
RuntimeDirectoryMode=0775
# Run ExecStart with User=sphinx / Group=sphinx
ExecStart=/usr/bin/searchd --config /etc/sphinx/sphinx.conf
ExecStop=/usr/bin/searchd --config /etc/sphinx/sphinx.conf --stopwait
KillMode=process
KillSignal=SIGTERM
SendSIGKILL=no
LimitNOFILE=infinity
TimeoutStartSec=infinity
#PIDFile=/var/run/sphinx/searchd.pid
PIDFile=/var/run/sphinxsearch/searchd.pid

[Install]
WantedBy=multi-user.target
Alias=sphinx.service
Alias=sphinxsearch.service

在这种情况下，我的 searchd 能够在重新启动后幸存下来。上一篇文章中的解决方案在我的情况下在 /var/run/sphinxsearch 目录在重启后删除之前重启后开始搜索的问题。

事实是 RHEL (CentOS) 7 无法感知“TimeoutStartSec”参数的“Infinity”值。您必须设置一个数值。例如，TimeoutStartSec=600
