mysql 8本地源碼安裝注意事項

1.安裝依賴

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

 　　2.下載源碼包

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

　　3.建立mysql用戶

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

 　　4.建立安裝目錄和數據目錄

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

三.安裝MySQL8.0.11

　　1.解壓源碼包

      tar -zxf mysql-boost-8.0.11.tar.gz

        2.編譯&安裝

      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

此處安裝1小時,源碼安裝

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.目錄權限修改

      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.啓動mysql

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

 ./mysql

mysql> flush privileges;         由於前面帶了--skip-grant-tables,這一步很重要.
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客戶端沒法登錄.

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,重啓mysqld,不要帶--skip-grant-tables
