mysql安装好是什么样子的

安装mysql服务yum 安装

[root@localhost ~]# ls /etc/yum.repos.d/ redhat.repo xx.repo [root@localhost ~]# rpm -ivh http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm 获取http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm 警告：/var/tmp/rpm-tmp.pSGnsG: 头V3 DSA/SHA1 Signature, 密钥 ID 5072e1f5: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:mysql57-community-release-el7-10 ################################# [100%] [root@localhost ~]# ls /etc/yum.repos.d/ mysql-community.repo mysql-community-source.repo redhat.repo xx.repo

启动mysql服务就ok

[root@localhost ~]# systemctl start mysqld [root@localhost ~]# systemctl status mysqld

二进制安装mysql

-下载mysql二进制安装包

wget https://downloads.mysql.com/archives/get/file/mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz

-创建用户和组

[root@localhost ~]# groupadd -r mysql [root@localhost ~]# useradd -M -s /sbin/nologin -g mysql mysql [root@localhost ~]#

[root@localhost ~]# tar -xf mysql-5.7.22-linux-glibc2.12-x86_64.tar.gz -C /usr/l ocal/

[root@localhost ~]# cd /usr/local/ [root@localhost local]# ln -s mysql-5.7.22-linux-glibc2.12-x86_64/ mysql [root@localhost local]#

[root@localhost local]# cd [root@localhost ~]# chown -R mysql.mysql /usr/local/mysql* [root@localhost ~]#

-添加环境变量

[root@localhost ~]# echo 'export PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh [root@localhost ~]# . /etc/profile.d/mysql.sh 重新读下 [root@localhost ~]#

[root@localhost ~]# mkdir /opt/data [root@localhost ~]# chown -R mysql.mysql /opt/data/ [root@localhost ~]#

[root@localhost ~]# /usr/local/mysql/bin/mysqld --initialize --user=mysql --datadir=/opt/data 2019-08-20T04:36:47.124341Z 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.

[root@localhost ~]# cat > /etc/my.cnf <<EOF > [mysqld] > basedir = /usr/local/mysql > datadir = /opt/data > socket = /tmp/mysql.sock > port = 3306 > pid-file = /opt/data/mysql.pid > user = mysql > skip-name-resolve > EOF [root@localhost ~]# cat /etc/my.cnf [mysqld] basedir = /usr/local/mysql datadir = /opt/data socket = /tmp/mysql.sock port = 3306 pid-file = /opt/data/mysql.pid user = mysql skip-name-resolve

-配置服务启动脚本

[root@localhost ~]# cp -a /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld [root@localhost ~]# sed -ri 's#^(basedir=).*#\1/usr/local/mysql#g' /etc/init.d/mysqld [root@localhost ~]# sed -ri 's#^(datadir=).*#\1/opt/data#g' /etc/init.d/mysqld

[root@localhost ~]# /etc/init.d/mysqld start Starting MySQL.Logging to '/opt/data/localhost.localdomain.err'. SUCCESS! [root@localhost ~]#

编译安装（源码安装）

wget http://downloads.mysql.com/archives/get/file/mysql-5.7.26.tar.gz (https://downloads.mysql.com/archives/手动下载，上传) 下载

[root@localhost ~]# yum -y install gcc gcc-c ncurses ncurses-devel cmake 安装过程省略…… [root@localhost ~]#

下载cmake编译工具

[root@localhost ~]# cd /usr/src/ [root@localhost src]wget http://www.cmake.org/files/v2.8/cmake-2.8.12.1.tar.gz 下载过程略。。。 [root@localhost src]# ls cmake-2.8.12.1.tar.gz

解压

[root@localhost src]# tar xf cmake-2.8.12.1.tar.gz [root@localhost src]# ls cmake-2.8.12.1 cmake-2.8.12.1.tar.gz

编译安装cmake

[root@localhost ~]# cd /usr/src/cmake-2.8.12.1 [root@localhost cmake-2.8.12.1]# ./configure && make && make install

编译安装mysql5.7.26

设置服务启动脚本

[root@local mysql]# cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld [root@local mysql]sed -ri 's#^(basedir=).*#\1/usr/local/mysql#g' /etc/init.d/mysqld [root@local mysql]# sed -ri 's#^(datadir=).*#\1/usr/local/mysql/data#g' /etc/init.d/mysqld

启动服务

[root@local mysql]# service mysqld start Starting MySQL.Logging to '/usr/local/mysql/data/96.err'. SUCCESS! [root@local mysql]# chkconfig mysqld on [root@local mysql]# ss -antl State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:111 *:* LISTEN 0 128 *:22 *:* LISTEN 0 80 :::3306 :::* LISTEN 0 128 :::111 :::* LISTEN 0 128 :::22
