centos7部署二进制mysql-5.6

目录

• 一.环境声明
• 二.程序部署

一.环境声明

[mysql-Server]
    主机名 = host-1
    系统 = centos-7.3
    地址 = 1.1.1.1
    软件 = mysql-5.6.39 3306

使用二进制包部署会下载比较大，大约500M左右，而源码包就几十M。但使用二进制包不用编译，部署较快，相比于yum可以自定义目录，方便维护。

二.程序部署

1.安装依赖

yum -y install autoconf libaio bison ncurses-devel

2.创建用户

groupadd mysql

useradd -g mysql -s /sbin/nologin mysql

3.清理centos7 默认自带数据库

yum -y remove mariadb mariadb-server

4.下载MySQL

wget https://dev.mysql.com/get/Downloads/MySQL-5.6/mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

5.安装

tar -xf mysql-5.6.39-linux-glibc2.12-x86_64.tar.gz

mv mysql-5.6.39-linux-glibc2.12-x86_64 /usr/local/mysql

mkdir /var/log/mysql

mkdir /usr/local/mysql/data

mysql即使root启动还是mysql用户运行的，所以要给权限

chown -R mysql:mysql /usr/local/mysql

chown -R mysql:mysql /usr/log/mysql

6.修改配置，具体再根据性能和需求修改

vim /etc/my.cnf

[mysql]
default-character-set=utf8
socket=/usr/local/mysql/mysql.sock
[mysqld]
skip-name-resolve
port = 3306
socket=/usr/local/mysql/mysql.sock
basedir=/usr/local/mysql
datadir=/usr/local/mysql/data
max_connection=200
character-set-server=utf8
default-storage-engine=INNODB
lower_case_table_name=1
max_allowed_packet=16M
log-error=/var/log/mysql/mysql.log
pid-file=/var/log/mysql/mysql.pid
bind-address = 0.0.0.0

7.启动服务

cd /usr/local/mysql

进行初始化操作

./scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql/ --datadir=/usr/local/mysql/data/

让mysql可以读

chown mysql:mysql /etc/my.cnf

8.加入systemctl

vim /usr/lib/systemd/system/mysql.service

[Unit]
Description=mysql
After=network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
ExecStart=/usr/local/mysql/support-files/mysql.server start
ExecReload=/usr/local/mysql/support-files/mysql.server restart
ExecStop=/usr/local/mysql/support-files/mysql.server stop
PrivateTmp=true

[Install]
WantedBy=multi-user.target

9.设置环境变量

echo 'PATH=$PATH':/usr/local/mysql/bin >> /etc/profile

source /etc/profile

10.启动并加入自启动

systemctl start mysql

systemctl enable mysql
