redis读取所有key和Value

1
./redis-cli -h 127.0.0.1 -p 6401 keys "*" | awk '{printf $0 ",";system("/data/redis/redis-cli -h 127.0.0.1 -p 6401 get " $0);}'

测试磁盘是否能正常读写

for i in {1..12};do echo 'test' > /data${i}/test ; done;

发送配置简单脚本

for i in {1..9}; do scp /etc/hosts root@flink00${i}:/etc/ ; done;

while read line ; do if [[ $line == node* ]]; then scp /data/spark/spark-2.1.1-bin-hadoop2.7/conf/spark-env.sh root@$line:/data/spark/spark-2.1.1-bin-hadoop2.7/conf/; fi; done < slaves ;

根据 hosts 中 ip 建立免密

while read line ; do if [[ $line == 172* ]]; then host=echo ${line} | cut -d ‘ ‘ -f 2; ssh-copy-id root@$host ; fi ; done < /etc/hosts ;

根据 hosts 中ip 分发 hosts

while read line ; do for var in $line ; do if [[ $var == 172* ]]; then scp /etc/hosts root@$var:/etc/ ; fi; done; done < /etc/hosts ;

openssl 升级指南

https://blog.csdn.net/lw545034502/article/details/102617250

下载：wget https://github.com/openssl/openssl/archive/OpenSSL_1_1_1-stable.zip

解压：unzip OpenSSL_1_1_1-stable.zip

编译：./config –prefix=/usr/local/openssl

安装：make && make install

备份：

  • mv /usr/bin/openssl /usr/bin/openssl.old
  • mv /usr/lib64/openssl /usr/lib64/openssl.old
  • mv /usr/lib64/libssl.so /usr/lib64/libssl.so.old

新版：

  • ln -s /usr/local/openssl/bin/openssl /usr/bin/openssl
  • ln -s /usr/local/openssl/include/openssl /usr/include/openssl
  • ln -s /usr/local/openssl/lib/libssl.so /usr/lib64/libssl.so

更新动态链接库数据：

echo “/usr/local/openssl/lib” >> /etc/ld.so.conf

ldconfig -v

python3.7 安装

https://blog.51cto.com/jinkcloud/2411644?source=dra

python3支持openssl版本最低为1.0.2，而系统比较老，自带的openssl版本为1.0.2

安装新版openssl

  1. 下载
    https://www.openssl.org/source/

  2. 安装

    1
    2
    3
    4
    5
    mkdir /usr/local/openssl
    tar xf openssl-1.1.1c.tar.gz
    cd openssl-1.1.1c/
    ./config --prefix=/usr/local/openssl shared zlib
    make && make install

  3. 配置共享库

    1
    2
    3
    echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/openssl/lib' >> ~/.bash_profile
       
       ~/.bash_profile
安装python3

  1. 下载
    https://www.python.org/downloads/source/

  2. 安装，指定刚刚安装的opensll

    1
    2
    3
    4
    5
    6
    7
    tar xf Python-3.7.3.tar.xz
    mkdir /usr/local/python3
    cd Python-3.7.3/
    ./configure prefix=/usr/local/python3 --with-openssl=/usr/local/openssl

    yum install zlib-devel
    make && make install

  3. 配置python3环境变量

    1
    2
    3
    4
    5
    vi /etc/profile
    #配置python
    export PYTHON_HOME=/usr/local/python3
    export PATH=$PYTHON_HOME/bin:$PATH
    source /etc/profile

    编译的时候能看到ssl成功加载

    ln -s /usr/local/python3/bin/python3 /usr/bin/python3

验证ssl模块

导入模块试试
