安装高版本GCC，解决编译中会遇到的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

# 后续开发包

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

# 上传cmake-3.19.3.tar.gz到/opt

cd /opt

tar -zxvf cmake-3.19.3.tar.gz

cd cmake-3.19.3

下载MySQL，选source，编译安装MySQL

# 上传mysql-boost-8.0.23.tar.gz到opt目录

配置MySQL

# 设置权限，查看是否有MySQL用户和用户组

cat /etc/passwd

cat /etc/group

# 如果没有，创建用户和用户组

groupadd mysql

useradd -g mysql mysql

# 修改/usr/local/mysql权限

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

初始化MySQL配置

vim ~/.zshrc

# 添加路径 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
