卸載mariadb

rpm -qa | grep mariadb

mariadb-libs-5.5.64-1.el7.x86_64

yum remove mariadb-libs.x86_64 -y

安裝高版本GCC，解決編譯中會遇到的GCC 5.3 or newer is required (-dumpversion says 4.8.5)

cd /opt

yum install centos-release-scl -y

yum install devtoolset-9 -y

scl enable devtoolset-9 zsh

gcc --version

# 后續開發包

yum -y groupinstall "Development tools"

yum -y install openssl-devel bison-devel ncurses-devel zlib-devel bzip2-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

下載編譯安裝cmake

# 上傳cmake-3.19.3.tar.gz到/opt

cd /opt

tar -zxvf cmake-3.19.3.tar.gz

cd cmake-3.19.3

./bootstrap

make && make install

下載MySQL，選source，編譯安裝MySQL

# 上傳mysql-boost-8.0.23.tar.gz到opt目錄

cd /opt

tar -zxvf mysql-boost-8.0.23.tar.gz

cd mysql-8.0.23

配置MySQL

# 設置權限，查看是否有MySQL用戶和用戶組

cat /etc/passwd

cat /etc/group

# 如果沒有，創建用戶和用戶組

groupadd mysql

useradd -g mysql mysql

# 修改/usr/local/mysql權限

chown -R mysql:mysql /usr/local/mysql

初始化MySQL配置

vim ~/.zshrc

# 添加路徑 export PATH=$PATH:/usr/local/mysql/bin

cd /usr/local/mysql

bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

cp support-files/mysql.server /etc/init.d/mysql

chkconfig mysql on

mkdir /var/lib/mysql

chmod 777 /var/lib/mysql

service mysql start

安裝Python3.9.1

# 上傳Python-3.9.1.tgz到opt目錄

cd /opt

tar -zxvf Python-3.9.1.tgz

mkdir /usr/local/python3.9

cd Python-3.9.1

./configure --prefix=/usr/local/python3.9 --with-ssl # --enable-optimizations

make && make install

ln -s /usr/local/python3.9/bin/python3 /usr/local/bin/python3.9

ln -s /usr/local/python3.9/bin/pip3 /usr/local/bin/pip3.9

python3.9 -m pip3 install --upgrade pip

which python3.9
