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)
