CentOS7.4 源码安装MySQL8.0的教程详解

MySQL 8 正式版 8.0.11 已发布,官方表示 MySQL 8 要比 MySQL 5.7 快 2 倍,还带来了大量的改进和更快的性能!

以下为本人2018.4.23日安装过程的记录。整个过程大概需要一个小时,make && make install过程需要的时间较长。

一.环境

CentOS7.4   64位  最小化安装

二.准备工作

1.安装依赖

yum -y install wget cmake gcc gcc-c++ ncurses ncurses-devel libaio-devel openssl openssl-devel

   2.下载源码包

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.11.tar.gz   (此版本带有boost)

3.创建mysql用户

groupadd mysql
    useradd -r -g mysql -s /bin/false mysql

   4.创建安装目录和数据目录

mkdir -p /usr/local/mysql
   mkdir -p /data/mysql

三.安装MySQL8.0.11

1.解压源码包

tar -zxf mysql-boost-8.0.11.tar.gz -C /usr/local

2.编译&安装

cd /usr/local/mysql-8.0.11
   cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/mysql-8.0.11/boost 
   make && make install

3.配置my.cnf文件     

cat /etc/my.cnf
   [mysqld]
   server-id=1
   port=3306
   basedir=/usr/local/mysql
   datadir=/data/mysql
    ##请根据实际情况添加参数

   4.目录权限修改    

chown -R mysql:mysql /usr/local/mysql
   chown -R mysql:mysql /data/mysql
   chmod 755 /usr/local/mysql -R
   chmod 755 /data/mysql -R

5.初始化

bin/mysqld --initialize --user=mysql --datadir=/data/mysql/
   bin/mysql_ssl_rsa_setup

   6.启动mysql  

bin/mysqld_safe --user=mysql &

   7.修改账号密码

bin/mysql -uroot -p
   mysql> alter user 'root'@'localhost' identified by "123456";
    mysql> show databases;
    +--------------------+
    | Database      |
    +--------------------+
    | information_schema |
    | mysql       |
    | performance_schema |
    | sys        |
    +--------------------+
    4 rows in set (0.00 sec)
    ##添加远程特账号
    mysql> create user root@'%' identified by '123456';
    Query OK, 0 rows affected (0.08 sec)
    mysql> grant all privileges on *.* to root@'%';
    Query OK, 0 rows affected (0.04 sec)
    mysql> flush privileges;
    Query OK, 0 rows affected (0.01 sec)

   8.创建软链接(非必要)

ln -s /usr/local/mysql/bin/* /usr/local/bin/
    mysql -h 127.0.0.1 -P 3306 -uroot -p123456 -e "select version();"
    mysql: [Warning] Using a password on the command line interface can be insecure.
    +-----------+
    | version() |
    +-----------+
    | 8.0.11  |
    +-----------+

   9.添加到启动(非必要)

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

特此说明:MySQL官方推荐使用二进制安装的方式。(下图为官方文档截图)
