mycat 启动报 Unable to start JVM: No such file or directory (2)【转】(mycat启动命令)
mycat 启动失败,查看日志 /mycat/logs/wrapper.log 发现如下信息

解决方法:
原因可能是 JVM 参数没有配置或者配置错误
处理方案:
在 mycat/conf/wrapper.conf 下增加:
wrapper.java.command=java 安装目录 /bin/java
例如:
wrapper.java.command=/home/hadoop/software/jdk1.8.0_181/bin/java

"libcudart.so.8.0 cannot open shared object file: No such file or directory"
解决办法是将一些文件复制到 /usr/local/lib 文件夹下:
#注意自己 CUDA 的版本号!
sudo cp /usr/local/cuda-8.0/lib64/libcudart.so.8.0 /usr/local/lib/libcudart.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcublas.so.8.0 /usr/local/lib/libcublas.so.8.0 && sudo ldconfig
sudo cp /usr/local/cuda-8.0/lib64/libcurand.so.8.0 /usr/local/lib/libcurand.so.8.0 && sudo ldconfig
或者
sudo ldconfig /usr/local/cuda/lib64
bash: history: : cannot create: No such file or directory 问题处理!
问题如图
root@VM_0_13_centos /]# /etc/init.d/metasploit stop
worker is stopped
Exiting!
metasploit is stopped
prosvc is stopped
nginx is stopped
/opt/metasploit/postgresql/scripts/ctl.sh : postgresql stopped
bash: history: : cannot create: No such file or directory
[root@VM_0_13_centos /]# cd /root/
bash: history: : cannot create: No such file or directory
[root@VM_0_13_centos root]# ls
bash: history: : cannot create: No such file or directory
无论我在命令行输入什么命令都会提示
bash: history: : cannot create: No such file or directory
问题解决
[root@VM_0_13_centos ~]# echo $HISTROTY
bash: history: : cannot create: No such file or directory
设置变量
[root@VM_0_13_centos ~]# cat .bash_profile #打开
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
HOME=/root
HISTFILE=/root/.bash_history #添加
export PATH
[root@VM_0_13_centos ~]# source .bash_profile #生效
#一切正常
[root@VM_0_13_centos ~]# ls
[root@VM_0_13_centos ~]# cat .bash_profile
cache.h:40:18: fatal error: zlib.h: No such file or directory
1、问题安装git 过程中 make出现问题
cache.h:40:18: Fatal error: zlib.h: No such file or directory #include <zlib.h>
2、解决方法
[root@rhelpc1 git-2.9.5]# yum install zlib zlib-devel -y
3、测试make
[root@rhelpc1 git-2.9.5]# make
问题解决。

CentOS 7.x 关闭 / 开启防火墙出现 Unit iptables.service failed to load: No such file or directory 问题解决
一直用 CentOS 6.x,今天用 CentOS7.3 版本时,防火墙配置后执行 service iptables start 出现”Failed to restart iptables.service: Unit iptables.service failed to load: No such file or directory.” 错误,
错误信息如下:
在 CentOS 7 或 RHEL 7 或 Fedora 中防火墙由 firewalld 来管理,当然你可以还原传统的管理方式。或则使用新的命令进行管理。
当然我们可以还原传统的管理方式:
1、执行以下命令
systemctl stop firewalld
systemctl mask firewalld
2、安装 iptables-services
yum install iptables-services
3、设置开机启动
systemctl enable iptables
4、iptables 启动 / 停止 / 重启
systemctl start iptables
systemctl stop iptables
systemctl restart iptables
systemctl reload iptables
5、保存设置
service iptables save
防火墙开放某个端口,在 /etc/sysconfig/iptables 文件中加入以下内容
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT
然后执行以下命令生效
/usr/libexec/iptables/iptables.init save
