1.安装Mysql数据库

①下载Mysql数据包

wgethttp://mirrors.sohu.com/mysql/MySQL-5.6/mysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

②在/usr/local/src下解压缩文件包

tarzxvfmysql-5.6.35-linux-glibc2.5-x86_64.tar.gz

③将解压后的文件包改名为mysql

mvmysql-5.6.35-linux-glibc2.5-x86_64/usr/local/mysql

④创建名为mysql的用户以及/data/文件夹用于存放mysql数据库的数据

useraddmysqlmkdir/data/

⑤运行脚本安装数据库

[root@test_01mysql]#./scripts/mysql_install_db--user=mysql--datadir=/data/mysqlFATALERROR:pleaseinstallthefollowingPerlmodulesbeforeexecuting./scripts/mysql_install_db:Data::Dumper

此处出现错误，提示需要先安装Dumper，安装perl-Data-Dumper后解决问题

[root@test_01mysql]#yuminstall-yperl-Data-Dumper

⑥拷贝mysql模板配置文件至/etc/my.cnf。并修改socket和datadir的值为如下内容

datadir=/data/mysqlsocket=/tmp/mysql.sock

⑦配置启动文件

将mysql.server文件拷贝至/etc/init.d/mysqld，配置basedir和datadir

[root@test_01mysql]#cpsupport-files/mysql.server/etc/init.d/mysqldbasedir=/usr/local/mysqldatadir=/data/mysql

将mysqld加入启动服务中

[root@test_01mysql]#chkconfig--addmysqld[root@test_01mysql]#chkconfig--list注意：该输出结果只显示SysV服务，并不包含原生systemd服务。SysV配置数据可能被原生systemd配置覆盖。如果您想列出systemd服务,请执行'systemctllist-unit-files'。欲查看对特定target启用的服务请执行'systemctllist-dependencies[target]'。mysqld0:关1:关2:开3:开4:开5:开6:关netconsole0:关1:关2:关3:关4:关5:关6:关network0:关1:关2:开3:开4:开5:开6:关基于xinetd的服务：chargen-dgram:关chargen-stream:关daytime-dgram:关daytime-stream:关discard-dgram:关discard-stream:关echo-dgram:关echo-stream:关tcpmux-server:关time-dgram:关time-stream:关

⑧启动服务
