龙少的Linux配置大全

一、部署jar包

　　service mysqld restart <==> 　　systemctl restart mysqld
　　ps -ef | grep spring-boot-juzimi-0.0.1-SNAPSHOT.jar
　　java -jar spring-boot-juzimi-0.0.1-SNAPSHOT.jar >temp.txt &
　　kill -9 PID

二、mysql

　　yum install mysql-server mysql mysql-devel -y
　　vim /etc/my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
character-set-server=utf8
bind-address=0.0.0.0

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

　　如果缺失mysql.sock，则给/var/lib/mysql文件夹添加所有权限，即：chmod 777 /var/lib/mysql

三、连接远程linux上的mysql

　　进入mysql，执行以下语句：

# 允许所有用户远程访问，修改用户名和密码为你自己的(root, admin)
GRANT ALL ON *.* TO 'root'@'%' IDENTIFIED BY 'admin' WITH GRANT OPTION;
# 更新权限
FLUSH PRIVILEGES;

1. mysql跳过密码验证

　　在/etc/my.cnf的mysqld下添加skip-grant-tables
　　重启mysql服务，执行mysql -uroot -p，password可以直接回车跳过。

2. 开机自启mysqld

　　systemctl enable mysqld

四、qt安装

　　chmod +x qt*.run
　　/qt*.run

五、jdk1.8.0安装

　　mv *.tar.gz /usr/java/
　　tar -xzvf *.tar.gz
　　vim /etc/profile

export JAVA_HOME=/usr/java/jdk1.8.0_231
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH

六、RHEL8

1. 共享文件夹

　　vim /etc/rc.local

vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other -o nonempty

　　偶尔出现不好使的情况，查看文件权限：
　　“ll /etc/rc.local” 发现 “-rwxrwxrwx … /etc/rc.local -> rc.d/rc.local”
　　在/etc/下发现rc.d文件夹，里面还有一个rc.local文件，ll发现缺少很多权限，将其修改权限，问题解决：
　　chmod 777 /etc/rc.d/rc.local

2. 本地yum源配置

　　find / -name BaseOS
　　将结果的BaseOS路径复制，比如是：/run/media/ls/RHEL-8-0-0-BaseOS-x86_64/BaseOS
　　vim /etc/yum.repos.d/media.repo

# "/run/media/ls/RHEL-8-0-0-BaseOS-x86_64/" is previous(find / -name BaseOS) url
[BaseOS]
name=BaseOS
baseurl=file:///run/media/ls/RHEL-8-0-0-BaseOS-x86_64/BaseOS
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
enabled=1

[AppStream]
name=AppStream
baseurl=file:///run/media/ls/RHEL-8-0-0-BaseOS-x86_64/AppStream
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-beta

　　yum repolist

3. 清华dnf源配置

　　vim /etc/yum.repos.d/rhel-8-beta.repo

　　dnf clean all
　　dnf makecache

七、putty安装（不推荐安装）

　　wget https://the.earth.li/~sgtatham/putty/0.73/putty-0.73.tar.gz
　　tar -xzvf *.tar.gz

八、vim配置：

1. 克隆到本地

git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim

2. 创建taglist数据库

ctags -I __THROW -I __MALLOC_DEPRECATED -I __REDIRECT -I __REDIRECT_NTH -I __REDIRECT_NTHNL -I __THROWNL -I __attribute_const__ -I __attribute_deprecated__ -I __attribute_malloc__ -I __attribute_pure__ -I __wur -I __nonnull -I __attribute__ -R --fields=+ialS --extra=+q --c-kinds=+px --c++-kinds=+px -f ~/.vim/systags /usr/include/ /usr/local/include/

3. 编辑配置文件

　　vim ~/.vimrc

4. 自动下载插件

1. 先保存上面的配置

2. 执行自动下载插件命令
:PluginInstall
3. 保存并退出，下次再使用vim时减小
:wqa

九、MPlayer安装（不推荐安装）

　　自己安装的软件都放在这个目录：cd /usr/local/share/
　　安装依赖yasm(红帽8)：wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
　　tar -xzvf yasm-1.3.0.tar.gz
　　cd yasm-1.3.0/
　　./configure
　　make
　　make install
　　返回安装目录：cd …
　　wget http://www.mplayerhq.hu/MPlayer/releases/MPlayer-1.4.tar.gz
　　tar -xzvf MPlayer-1.4.tar.gz
　　cd MPlayer-1.4/
　　./configure
　　make
　　make install

十、红帽8中文输入法：

　　dnf install ibus-libpinyin.x86_64 -y
　　设置-语言-添加-中文-中文拼音
　　win+space切换输入法

十一、RHEL8最小化安装：

1. 设置语言环境：

　　vi /etc/profile

export LC_ALL=zh_CN.UTF-8

　　vi /etc/locale.config

LANG="zh_CN.UTF-8"
LC_ALL="zh_CN.UTF-8"

　　source /etc/profile
　　source /etc/locale.config

2. 查看网卡：

　　ip addr

3. 设置网卡：

　　vi /etc/sysconfig/network-scripts/ifcfg-ens160

" 修改
BOOTPROTO=static
ONBOOT=yes
" 添加
IPADDR=192.168.1.6
PREFIX=24
GATEWAY=192.168.1.1
NETMASK=255.255.255.0
DNS1=114.114.114.114

4. 重启网卡：

　　systemctl restart NetworkManager

十二、XShell6连接rhel8mini有警告：

WARNING! The remote SSH server rejected X11 forwarding request.

　　yum install xorg-x11-xauth -y
　　systemctl restart sshd

十三、ctags完整版：忽略一堆宏，可以找到被宏干扰的库函数。

　　-f：指定tags包生成路径
　　最后的 /usr/include/ /usr/local/include/ 是指定要打包的路径，常用的就这俩，可自行添加。

ctags -I __THROW -I __MALLOC_DEPRECATED -I __REDIRECT -I __REDIRECT_NTH -I __REDIRECT_NTHNL -I __THROWNL -I __attribute_const__ -I __attribute_deprecated__ -I __attribute_malloc__ -I __attribute_pure__ -I __wur -I __nonnull -I __attribute__ -R --fields=+ialS --extra=+q --c-kinds=+px --c++-kinds=+px -f ~/.vim/systags /usr/include/ /usr/local/include/

十四、windows远程桌面连接(xrdp服务)

yum install epel-release xrdp -y
systemctl start xrdp
systemctl enable xrdp

十五、Linux知识

1. 设置普通用户不能修改自己密码

　　chmod 755 /usr/bin/passwd 之后，普通用户将不能修改自己的密码。

2. 开机自动加载界面类型：

　　systemctl set-default xxx.target
　　字符界面：multi-user.target
　　图形界面：graphical.target

3. 动态库.so创建：

　　gcc -c *.c -Wall -fPIC
　　gcc *.o -o libls.so -shared

4. 查看当前路径的大小：

　　du -sh
　　du -sh *

5. grep查找路径下所有文件包含某个字符串

　　grep [“字符串”] -r [路径] -n
　　find . -name “*.cpp” | xargs grep “myfunction”

7. 防火墙操作：

　　关闭/开启防火墙：systemctl stop/start firewalld.service
　　禁止/允许防火墙开机自动启动：systemctl disable/enable firewalld.service
