CentOS7通过yum方式安装mysql8

  • mysql8增加了许多新特性，比如支持JSON格式，密码认证方式改成了”caching-sha2-password”，不过很多客户端还不支持的，在将来肯定都会支持的。如果客户端不支持的话还是可以改成”mysql_native_password”方式。
#!/bin/bash
yum install wget -y
wget https://repo.mysql.com//mysql80-community-release-el7-1.noarch.rpm
rpm -Uvh mysql80-community-release-el7-1.noarch.rpm
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
yum install mysql-community-server -y
systemctl start mysqld.service
systemctl enable mysqld.service
systemctl status mysqld.service

#查看mysql自己生成的临时密码
grep 'temporary password' /var/log/mysqld.log

## 由于 default_password_lifetime 的存在，必须修改默认密码之后才能使用
alter user user() identified by "yourpassword";

CENTOS7通过YUM方式安装PHP7

  • CENTOS7.X自带源里面的PHP版本太老旧了，已经不适合大多数的场景。下面介绍的是通过YUM方式安装的PHP7，优点是缺少模块，可以很快的安装，不像通过源码按照的每次需要编译一下，比较繁琐。这种方式的缺点就是YUM源在国外，速度较慢。
#!/bin/bash 
yum remove php*
yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum -y install yum-utils
yum-config-manager --enable remi-php74
yum update
yum install php php-zip php-bcmath php-cli php-common php-dba php-devel \
    php-embedded php-enchant php-fpm php-gd php-imap php-interbase php-intl php-ldap php-xlswriter  \
    php-mbstring php-mysqlnd php-odbc php-opcache php-sodium \
    php-pdo php-pdo_dblib php-pear php-pecl-apcu php-pecl-imagick php-pecl-memcached \
    php-pecl-mongodb php-pecl-redis php-pgsql php-process \
    php-pspell php-recode php-snmp php-soap php-tidy php-xml php-xmlrpc -y
systemctl start  php-fpm
systemctl enable  php-fpm
systemctl status  php-fpm
php -v

Centos6.x/7.x下面安装特定的python版本

  • 由于openssl出现问题，在源码编译安装python3的时候，会一直不成功，我测试了几个openssl的版本最后编译的时候都不能通过，最后根据python3给出的提示，安装了LibreSSL来代替openssl，LibreSSL是在看到openssl有问题的基础上开发出来的用来替代openssl的

寻觅

风儿啊！你要把我推到哪里去呀！
这里可全都是黑暗啊
我什么都看不见了！


风儿啊！你要把我推到哪里去啊！
这里可全都是山呀！
我都找不到回家的路了！


风儿啊！你到底要把我推到哪里去呀！
我的眼里可全都是泪水啊！
