MySQL8——源码安装

一.环境

ubuntu18.10(CentOS7由于gcc版本过低已经无法通过编译)

二.准备工作

1.安装依赖

apt-get install -y gcc g++ cmake build-essential bison libncurses5-dev openssl libssl-dev

2.下载源码包

wget https://cdn.mysql.com//Downloads/MySQL-8.0/mysql-boost-8.0.15.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MySQL8.0.15

1.解压源码包

tar -zxvf mysql-boost-8.0.15.tar.gz -C /usr/local/src

2.编译&安装

cd /usr/local/src/mysql-8.0.15
cmake . -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DMYSQL_TCP_PORT=3306 -DWITH_BOOST=/usr/local/src/mysql-8.0.15/boost -DFORCE_INSOURCE_BUILD=1
make && make install

3.配置my.cnf文件

文件参数很多,这里就不一一列举
vim /etc/my.cnf

[mysqld]
server-id=1
port=3306
basedir=/usr/local/mysql
datadir=/data/mysql
socket=/data/mysql/mysql.sock
max_allowed_packet=1G
net_read_timeout=300
net_write_timeout=600

[client]
socket=/data/mysql/mysql.sock

##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

cd /usr/local/mysql

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)

##添加远程连接账号

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() |
    +-----------+
    | 8.0.15 |
    +-----------+

9.添加到启动(非必要)

cp support-files/mysql.server /etc/init.d/mysqld
/lib/systemd/systemd-sysv-install enable mysqld
