Linux-安装-MySQL5.7
作者：互联网
1、二进制安装MySQL5.7
安装相关包
yum -y install libaio numactl-libs
用户和组
groupadd mysql useradd -r -g mysql -s /bin/false mysql
[root@centos7-liyj ~]#groupadd mysql [root@centos7-liyj ~]#useradd -r -g mysql -s /bin/false mysql #创建系统用户 [root@centos7-liyj ~]#tail /etc/passwd ftp:x:14:50:FTP User:/var/ftp:/sbin/nologin nobody:x:99:99:Nobody:/:/sbin/nologin systemd-network:x:192:192:systemd Network Management:/:/sbin/nologin dbus:x:81:81:System message bus:/:/sbin/nologin polkitd:x:999:998:User for polkitd:/:/sbin/nologin sshd:x:74:74:Privilege-separated SSH:/var/empty/sshd:/sbin/nologin postfix:x:89:89::/var/spool/postfix:/sbin/nologin liyanjin:x:1000:1000:liyanjin:/home/liyanjin:/bin/bash tss:x:59:59:Account used by the trousers package to sandbox the tcsd daemon:/dev/null:/sbin/nologin mysql:x:998:1001::/home/mysql:/bin/false用户和组建立
下载二进制程序文件
下载路径http://mirrors.163.com/mysql/Downloads/MySQL-5.7/
Linux系统中：http://mirrors.163.com/mysql/Downloads/MySQL-5.7/mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz
准备程序文件
[root@centos7-liyj ~]#tar xf mysql-5.7.37-linux-glibc2.12-x86_64.tar.gz -C /usr/local/ [root@centos7-liyj ~]#cd /usr/local/ [root@centos7-liyj /usr/local]#ln -s mysql-5.7.37-linux-glibc2.12-x86_64/ mysql [root@centos7-liyj /usr/local]#chown -R root.root /usr/local/mysql/ [root@centos7-liyj /usr/local]#echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh [root@centos7-liyj /usr/local]#. /etc/profile.d/mysql.sh
修改前文件内容属组属主 [root@centos7-liyj /usr/local/mysql]#ll total 272 drwxr-xr-x 2 root root 4096 May 10 09:37 bin drwxr-xr-x 2 root root 55 May 10 09:37 docs drwxr-xr-x 3 root root 4096 May 10 09:37 include drwxr-xr-x 5 root root 230 May 10 09:37 lib -rw-r--r-- 1 7161 31415 259253 Nov 30 04:09 LICENSE drwxr-xr-x 4 root root 30 May 10 09:37 man -rw-r--r-- 1 7161 31415 566 Nov 30 04:09 README drwxr-xr-x 28 root root 4096 May 10 09:37 share drwxr-xr-x 2 root root 90 May 10 09:37 support-files 修改后文件内容属组属主 [root@centos7-liyj /usr/local/mysql]#ll total 272 drwxr-xr-x 2 root root 4096 May 10 09:37 bin drwxr-xr-x 2 root root 55 May 10 09:37 docs drwxr-xr-x 3 root root 4096 May 10 09:37 include drwxr-xr-x 5 root root 230 May 10 09:37 lib -rw-r--r-- 1 root root 259253 Nov 30 04:09 LICENSE drwxr-xr-x 4 root root 30 May 10 09:37 man -rw-r--r-- 1 root root 566 Nov 30 04:09 README drwxr-xr-x 28 root root 4096 May 10 09:37 share drwxr-xr-x 2 root root 90 May 10 09:37 support-files权限修改前后对比
准备环境变量
[root@centos7-liyj /usr/local]#echo 'PATH=/usr/local/mysql/bin:$PATH' > /etc/profile.d/mysql.sh [root@centos7-liyj /usr/local]#. /etc/profile.d/mysql.sh
准备配置文件
[root@centos7-liyj /usr/local]#cp /etc/my.cnf{,.bak}
[root@centos7-liyj /usr/local]#vim /etc/my.cnf
[mysqld]
datadir=/data/mysql
skip_name_resolve=1
socket=/data/mysql/mysql.sock
log-error=/data/mysql/mysql.log
pid-file=/data/mysql/mysql.pid
[client]
socket=/data/mysql/mysql.sock
初始化数据库文件并提取root密码
[root@centos7-liyj /data]#mysqld --initialize --user=mysql --datadir=/data/mysql
[root@centos7-liyj /data/mysql]#awk '/temporary password/{print $NF}' /data/mysql/mysql.log
Bu_jLT.yr8,y

方式2: 生成 root 空密码
mysqld --initialize-insecure --user=mysql --datadir=/data/mysql
准备服务脚本和启动
[root@centos7-liyj /data/mysql]#cp /usr/local/mysql/support-files/mysql.server /etc/init.d/mysqld [root@centos7-liyj /data/mysql]#chkconfig --add mysqld [root@centos7-liyj /data/mysql]#systemctl start mysqld
