mysql 8.0.18 安装配置方法图文教程(linux)
本文记录了linux mysql 8.0.18 安装配置图文教程,供大家参考,具体内容如下
1、官网安装包下载地址
2、我这里通过xftp将安装包上传至Linux服务器
3.解压
解压命令:tar -xvf mysql-8.0.18-linux-glibc2.12-x86_64.tar
继续解压需要的那一个
命令: tar -xvf mysql-8.0.18-linux-glibc2.12-x86_64.tar.xz
重命名并移动到合适的路径
重命名 : mv mysql-8.0.18-linux-glibc2.12-x86_64 mysql
移动:
4.在/usr/local/mysql下创建data文件夹
?1 | # mkdir data |
5.初始化数据库,自动生成密码 需记录 等下要用
# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data
ps:中间遇到一个坑,初始化数据库时候报了错
具体错误为:bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
解决方法为:yum install libaio-devel.x86_64 原因是缺少了libaio这个东西 安装就完事了
再次执行初始化命令
得到初始化密码,需要记下,一会会用到
6.修改/usr/local/mysql 当前目录的用户
?1 2 | # chown -R root:root ./ # chown -R mysql:mysql data |
7.复制my-default.cnf这个文件到etc/my.cnf去
具体命令为:
?1 2 3 4 5 | # cd support-files/ # touch my- default .cnf # chmod 777 ./my- default .cnf # cd ../ # cp support-files/my- default .cnf /etc/my.cnf |
8.完了之后配置my.cnf
?1 | vim /etc/my.cnf |
内容:
?1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # Remove leading # to turn on a very important data integrity option : logging # changes to the binary log between backups. # log_bin # These are commonly set , remove the # and set as required. basedir = /usr/ local /mysql datadir = /usr/ local /mysql/data socket = /tmp/mysql.sock log-error = /usr/ local /mysql/data/error.log pid-file = /usr/ local /mysql/data/mysql.pid tmpdir = /tmp port = 5186 #lower_case_table_names = 1 # server_id = ..... # socket = ..... #lower_case_table_names = 1 max_allowed_packet=32M default -authentication-plugin = mysql_native_password #lower_case_file_system = on #lower_case_table_names = 1 log_bin_trust_function_creators = ON # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values . # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES |
如果后期mysql运行报错,可以直接到log-error = /usr/local/mysql/data/error.log目录下直接查看错误日志
命令:cat /usr/local/mysql/data/error.log
9.开机自启,进入/usr/local/mysql/support-files进行设置
?1 2 3 | # cd support-files/ # cp mysql.server /etc/init.d/mysql # chmod +x /etc/init.d/mysql |
10.注册服务
?1 | # chkconfig --add mysql |
11.查看是否成功
12.etc/ld.so.conf要配置路径,不然报错
?1 | # vim /etc/ld.so.conf |
添加如下内容:
?1 | /usr/ local /mysql/lib |
13.配置环境变量
?1 2 | # vim /etc/profile # source /etc/profile |
添加如下内容:
?1 2 | #MYSQL ENVIRONMENT export PATH=$PATH:/usr/ local /mysql/bin:/usr/ local /mysql/lib |
14.登录 需要用到上面的生成的密码
?1 2 3 4 5 6 7 8 9 10 | #启动mysql服务 [root@localhost bin]# service mysql start Starting MySQL.Logging to '/usr/local/mysql/data/error.log' . .. SUCCESS! [root@localhost bin]# #修改mysql密码 mysql> alter user 'root' @ 'localhost' identified by '123456' ; Query OK, 0 rows affected (0.02 sec) mysql> |
ps:第二个坑,在启动时出现错误 详情为:
Starting MySQL...The server quit without updating PID file [FAILED]cal/mysql/data/mysql.pid).
该错误翻了一下午,绕了一大圈,最终问题是my.cnf文件配置问题,千万不能以为加了#就是注释掉了,自己检查了n遍,觉得没有错,结果就是不行,没有办法找了一份另一台服务器的my.cnf配置,复制替换稍加修改,解决问题。
大功告成!可以使用可视化工具进行数据库连接了。
安装完成。
