对于centeros 7.0 以上版本 想装mysql 需要先要卸载mariadb
rpm -qa | grep mariadb 查看已安装的mariadb
删除：rpm -e --nodeps mariadb名称
再查看一次：rpm -qa | grep mariadb 看是否存在
yum update -y
yum -y install gcc pcre pcre-devel zlib zlib-devel openssl openssl-devel
1：安装libffi-devel包
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libffi-devel-3.0.13-18.el7.x86_64.rpm
rpm -ivh libffi-devel-3.0.13-18.el7.x86_64.rpm
2：安装gcc
yum install -y gcc gcc-c++ openssl-devel zlib-devel
3：安装sqlite3
wget https://www.sqlite.org/2019/sqlite-autoconf-3300100.tar.gz
tar -zxvf sqlite-autoconf-3300100.tar.gz
cd sqlite-autoconf-3300100
./configure --prefix=/usr/local
make && make install
vim ~/.bashrc
按i键进行编辑
在最后一行插入export LD_LIBRARY_PATH="/usr/local/lib"
按esc键然后按：wq进行保存退出
mv /usr/bin/sqlite3 /usr/bin/sqlite3_old
ln -s /usr/local/bin/sqlite3 /usr/bin/sqlite3
4:安装vim
yum -y install vim*
一、安装mysql8.0.17
1：进入/usr/local目录下 ,创建mysql文件夹
2：使用命令“yum install wget 安装wget，接下来在线安装mysql。使用命令
wget http://dev.mysql.com/get/Downloads/mysql80-community-release-el7-3.noarch.rpm
3：安装mysql80-community-release-el7-3.noarch.rpm包。
使用命令 rpm -ivh mysql80-community-release-el7-3.noarch.rpm
4：使用命令 “yum install mysql-community-server”安装mysql。安装过程中提示 Is this ok [y/d/N]: 直接属于y即可，请耐心等待安装完成
5：安装完成后启动mysql服务，生成随机密码，可以使用这密码登录数据库
systemctl start mysqld
验证是否启动
systemctl status mysqld
grep 'temporary password' /var/log/mysqld.log
6：更新root密码
mysql -u root -p
输入上面随机的密码
ALTER USER 'root'@'localhost' IDENTIFIED BY '你的密码（包含大小写、数字和特殊字符）';
7：CREATE USER 'root'@'%' IDENTIFIED BY '上面设置的密码';
GRANT ALL ON *.* TO 'root'@'%' WITH GRANT OPTION;
8：更新root密码否则，远程登录会报错
ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '你设置的密码';
二、安装datagrip
1：下载软件：https://www.jetbrains.com/datagrip/?fromMenu
2：解压软件：下载之后解压缩

3：汉化
进入DataGrip-2019.2.6/lib/把resources_en.jar删除，然后把resources_cn.jar复制到lib的目录里
4：添加快捷方式
cd /usr/share/applications
vim DataGrip.Desktop
[Desktop Entry]
Name=DataGrip
Type=Application
Exec=/opt/datagrip/DataGrip-2018.2.4/bin/datagrip.sh
Icon=/opt/datagrip/DataGrip-2018.2.4/bin/datagrip.png

记得要:wq保存退出
cp /usr/share/applications/DataGrip.Desktop /root/桌面/
chown root /root/桌面/DataGrip.Desktop
三、安装python3.8
