mysql 8本地源码安装注意事项

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

2.编译&安装

cd 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=./boost make && make install

此处安装1小时,源码安装

3.配置my.cnf文件

vim /etc/my.cnf

[client] port = 3306 socket = /data/mysql/mysql.sock [mysqld_multi] mysqld = /usr/bin/mysqld_safe mysqladmin = /usr/bin/mysqladmin log = /var/log/mysqld_multi.err [mysqldump] quick max_allowed_packet = 16M

[mysql] no-auto-rehash [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout [mysqld] port = 3306 socket = /data/mysql/mysql.sock basedir=/usr/local/mysql key_buffer_size = 16M max_allowed_packet = 1M table_open_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M log-bin-trust-function-creators = 1 expire_logs_days = 1 max_connections = 600 skip-external-locking skip-name-resolve datadir=/data/mysql character_set_server = utf8 log-bin = mysql-bin max_allowed_packet=64M # Mandatory Settings server-id= 1 binlog_format=ROW default_storage_engine=InnoDB

innodb_autoinc_lock_mode=2

　　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/ ./mysql_ssl_rsa_setup

　　6.启动mysql

./mysqld_safe --user=mysql --skip-grant-tables &

./mysql

mysql> flush privileges; 因为前面带了--skip-grant-tables,这一步很重要. Query OK, 0 rows affected (0.04 sec)

mysql> alter user 'root'@'localhost' identified by "123456"; Query OK, 0 rows affected (0.07 sec)

mysql> create user root@'%' identified WITH mysql_native_password by '123456'; 8.1不加WITH mysql_native_password,windows客户端无法登陆.

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)

退出mysql,重启mysqld,不要带--skip-grant-tables
