root@sun-virtual-machine:/opt# mkdir /mydata/data -pv
root@sun-virtual-machine:/opt# groupadd -r mysql
root@sun-virtual-machine:/opt# useradd -g mysql -r -s /sbin/nologin -M -d /mydata/data mysql
-r, --system 创建一个系统账户
-s, --shell SHELL新账户的登录 shell
-M, --no-create-home不创建用户的主目录
-d, --home-dir HOME_DIR 新账户的主目录
-g, --gid GROUP新账户主组的名称或 ID
root@sun-virtual-machine:/# chown -R mysql:mysql /mydata/data
root@sun-virtual-machine:/# tar xf /root/mariadb-10.0.28-linux-glibc_214-x86_64.tar.gz -C /usr/local
root@sun-virtual-machine:/# cd /usr/local
root@sun-virtual-machine:/usr/local# ln -sv mariadb-10.0.28-linux-x86_64 mysql
root@sun-virtual-machine:/usr/local/mysql# cd mysql
root@sun-virtual-machine:/usr/local/mysql# chown -R mysql:mysql .
root@sun-virtual-machine:/usr/local/mysql# apt-get install libaio-dev 安装之后才能初始化成功 否则报错缺少它
root@sun-virtual-machine:/usr/local/mysql# scripts/mysql_install_db --user=mysql --datadir=/mydata/data
root@sun-virtual-machine:/usr/local/mysql# chown -R root .
root@sun-virtual-machine:/usr/local/mysql# cp support-files/my-large.cnf /etc/my.cnf
并修改此文件中thread_concurrency的值为你的CPU个数乘以2,比如这里使用如下行:
thread_concurrency = 2
另外还需要添加如下行指定mysql数据文件的存放位置:
datadir = /mydata/data
root@sun-virtual-machine:/usr/local/mysql# cp support-files/mysql.server /etc/init.d/mysqld
root@sun-virtual-machine:/usr/local/mysql# chmod +x /etc/init.d/mysqld
root@sun-virtual-machine:/usr/local/mysql# /lib/systemd/systemd-sysv-install enable mysqld
root@sun-virtual-machine:/usr/local/mysql# systemctl start mysqld
在开机时启用一个服务:systemctl enable postfix.service
在开机时禁用一个服务:systemctl disable postfix.service
查看服务是否开机启动:systemctl is-enabled postfix.service
查看已启动的服务列表:systemctl list-unit-files|grep enabled
查看启动失败的服务列表:systemctl --failed
