MySQL是一款关系数据库管理系统，原开发者为瑞典MySQL AB公司，目前已属于Oracle公司产品之一。MySQL因性能高、成本低、可靠性好，已经成为最流行的开源数据库，广受个人建站爱好者青睐。
实验环境
操作系统：CentOS 7.9
MySQL：5.7.32
服务端篇
第一步 安装依赖包
- # yum -y install wget vim make cmake gcc gcc-c++ openssl-devel bison-devel ncurses-devel
第二步 下载、解压源码包
- # cd /usr/local/src/
- # wget --no-check-certificate https://cdn.mysql.com//Downloads/MySQL-5.7/mysql-boost-5.7.32.tar.gz
- # tar xzf mysql-boost-5.7.32.tar.gz
第三步 新建用户组、用户
- # groupadd mysql
- # useradd mysql -M -g mysql -s /sbin/nologin
第四步 编译安装MySQL（按需添加更多功能模块）
- # cd /usr/local/src/mysql-5.7.32
- # cmake \
- -DCMAKE_INSTALL_PREFIX=/usr/local/mysql \
- -DSYSCONFDIR=/etc \
- -DMYSQL_TCP_PORT=3306 \
- -DEXTRA_CHARSETS=all \
- -DDEFAULT_CHARSET=utf8mb4 \
- -DDEFAULT_COLLATION=utf8mb4_general_ci \
- -DWITH_MYISAM_STORAGE_ENGINE=1 \
- -DWITH_INNOBASE_STORAGE_ENGINE=1 \
- -DWITH_PARTITION_STORAGE_ENGINE=1 \
- -DWITH_FEDERATED_STORAGE_ENGINE=1 \
- -DWITH_EMBEDDED_SERVER=1 \
- -DENABLED_LOCAL_INFILE=1 \
- -DWITH_BOOST=/usr/local/src/mysql-5.7.32/boost/boost_1_59_0
- # make
- # make install
第五步 优化数据库配置（4G-8G内存优化方案，仅供参考）
- # vim /etc/my.cnf
- [client]
- #password="123456"
- port=3306

- [mysqlhotcopy]
- interactive-timeout
第六步 修改数据库目录、配置文件权限
- # chown mysql:mysql /etc/my.cnf
- # chown -R mysql:mysql /usr/local/mysql
第七步 配置数据库环境变量
- # echo "export PATH="/usr/local/mysql/bin:$PATH"" >> /etc/profile
- # source /etc/profile
第八步 配置启动服务脚本、开机启动
- # cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld
- # chmod +x /etc/init.d/mysqld
- # chkconfig --add mysqld
- # chkconfig mysqld on
第九步 初始化数据库
- # mysqld --initialize-insecure --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
第十步 启动程序
- # service mysqld start
- # mysql
