Linux(CentOS6.5) 安装 MySQL5.7.24
1.下载MySQL5.7.24
2.安装mysql所需的依赖
[root@CentOS6 ~]# yum install -y gcc-c++ readline-devel zlib-devel bison cmake
3.解压mysql源码包，更改目录名称
-
3.1创建/usr/mysql目录：
[root@CentOS6 ~]# mkdir /usr/mysql -
3.2 将下载后的MySQL源码文件通过Xftp上传到/usr/mysql目录下
[root@CentOS6 mysql]# tar -zxvf mysql-5.7.24-linux-glibc2.12-x86_64.tar.gz
4.创建用户组
[root@CentOS6 ~]# groupadd mysql
[root@CentOS6 ~]# useradd -g mysql -s /bin/nologin -M mysql
[root@CentOS6 ~]# id mysql //查看用户是否创建成功
uid=500(mysql) gid=500(mysql) groups=500(mysql)
5.创建数据库目录和日志目录
[root@CnetOS6 ~]# mkdir /mysql /mysql/data /mysql/log
6.创建MySQL配置文件my.cnf
- 复制粘贴进去（basedir需要改）
[root@CnetOS6 ~]# vi /etc/my.cnf
[client]
port = 3306
socket = /tmp/mysql.sock
[mysqld]
server_id=10
port = 3306
user = mysql
socket = /tmp/mysql.sock
basedir = /usr/mysql/XXX #解压后的mysql目录（不要照抄）
datadir = /mysql/data
pid-file = /mysql/data/mysql.pid
max_connections = 1000
max_connect_errors = 1000
table_open_cache = 1024
max_allowed_packet = 128M
open_files_limit = 65535
# [innodb]
innodb_buffer_pool_size = 1024M
innodb_file_per_table = 1
innodb_write_io_threads = 4
innodb_read_io_threads = 4
innodb_purge_threads = 2
innodb_flush_log_at_trx_commit = 1
innodb_log_file_size = 512M
innodb_log_files_in_group = 2
innodb_log_buffer_size = 16M
innodb_max_dirty_pages_pct = 80
innodb_lock_wait_timeout = 30
innodb_data_file_path=ibdata1:1024M:autoextend
##log
log_error = /mysql/log/mysql-error.log
slow_query_log = 1
long_query_time = 1
slow_query_log_file = /mysql/log/mysql-slow.log
sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
7.更改目录权限
[root@CnetOS6 ~]# chown -R mysql:mysql /usr/local/mysql /mysql
8.初始化数据库
-
一定要进入mysql解压后的文件
[root@CnetOS6 mysql-5.7.24]# bin/mysqld --initialize --user=mysql --basedir=/usr/local/mysql --datadir=/mysql/data -
执行linux 中执行mysql命令 出现-bash: mysql: command not found
原因：因为系统默认会查找/usr/bin下的命令，由于mysql没有在这个目录下，所以出现not found。因此需要做一个软连接到/usr/bin目录下 。 执行命令： ln -s /usr/mysql/mysql-5.7.24/bin/mysql /usr/bin 其中/usr/mysql/mysql-5.7.24 为：mysql的安装路径
9.查看日志文件，读取数据库初始密码
[root@CnetOS6 mysql-5.7.24]# cat /mysql-5.7.24/log/mysql-error.log

10.MySQL数据库加密
[root@CentOS6 mysql-5.7.24]# bin/mysql_ssl_rsa_setup --datadir=/mysql/data
11.配置环境变量，并使其生效
[root@CentOS6 mysql-5.7.24]# echo 'export PATH=/usr/mysql/mysql-5.7.24/bin:$PATH' >> /etc/profile
[root@CentOS6 mysql-5.7.24]# source /etc/profile
12.配置MySQL服务
[root@CentOS6 mysql-5.7.24]# cp support-files/mysql.server /etc/init.d/mysql
13.启动数据库服务、进入到数据库中
[root@CentOS6 mysql-5.7.24]# /etc/init.d/mysql start
Starting MySQL.. SUCCESS!
[root@CentOS6 mysql-5.7.24]# mysql -u root -p
