配置目录

参考文献

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

注意：
　　需要安装一些插件，详情请见下方参考资料。

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 https://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 https://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、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
