CentOS7.2通用二进制格式安装mariadb-5.5.46-linux-x86_64.tar.gz
提前准备好mariadb-5.5.46-linux-x86_64.tar.gz
[[email protected] ~]# groupadd -r -g 306 mysql ###添加mysql用户
[[email protected] ~]# useradd -r -g 306 -u 306 mysql ###添加mysql组
[[email protected] dylan]# tar xf mariadb-5.5.46-linux-x86_64.tar.gz -C /usr/local/
[[email protected] dylan]# cd /usr/local/
[[email protected] local]# ln -sv mariadb-5.5.46-linux-x86_64/ mysql ###创建mysql链接
[[email protected] local]# cd mysql
[[email protected] mysql]# chown -R root.mysql ./* ###更改属组属组
[[email protected] mysql]# mkdir -pv /mydata/data ###创建数据目录
mkdir: 已创建目录 "/mydata"
mkdir: 已创建目录 "/mydata/data"
[[email protected] mysql]# chown -R mysql.mysql /mydata/data/ ###更改数据目录权限
[[email protected] mysql]# mkdir /etc/mysql
###将选择的配置文件复制至/etc/mysql/中，并重命名为my.cnf
[[email protected] mysql]# cp support-files/my-large.cnf /etc/mysql/my.cnf
[[email protected] mysql]# vim /etc/mysql/my.cnf ###编辑添加
thread_concurrency = 8
datadir = /mydata/data ###设定数据文件目录
innodb_file_per_table = ON
skip_name_resolve = ON ###跳过主机名解析
###复制mysqld的服务管理文件至/etc/rc.d/init.d并命名为mysqld
[[email protected] mysql]# cp support-files/mysql.server /etc/rc.d/init.d/mysqld
[[email protected] mysql]# ls -l /etc/rc.d/init.d/mysqld
-rwxr-xr-x. 1 root root 12196 6月 20 22:28 /etc/rc.d/init.d/mysqld
[[email protected] mysql]# chkconfig --add mysqld ###添加服务
###程序初始化，指定用户为mysql,数据目录为/mydata/data
[[email protected] mysql]# scripts/mysql_install_db --user=mysql --datadir=/mydata/data
[[email protected] mysql]# service mysqld start
Starting MySQL. ERROR! ###启动错误
###编辑selinux，关闭selinux
[[email protected] mysql]# vim /etc/selinux/config
SELINUX=disabled
[[email protected] mysql]# getenforce
Enforcing
[[email protected] mysql]# setenforce 0
[[email protected] mysql]# getenforce
Permissive
###此时启动依然出错，mysql读取配置文件不仅仅有一个，mysql进程会以此去找很多个位置，并使用最后的作为最终的配置。
[[email protected] /]# /usr/local/mysql/bin/mysql --help --verbose ###查看读取次序
/usr/local/mysql/bin/mysql Ver 15.1 Distrib 5.5.46-MariaDB, for Linux (x86_64) using read
line 5.1Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others.
Usage: /usr/local/mysql/bin/mysql [OPTIONS] [database]
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf ###读取顺序
###于是查看/etc/my.cnf文件，在log-error=/var/log/mariadb/mariadb.log中，于是查看/var/log/中不存在mariadb目录，需手动创建，或者将此注销掉，否则启动服务会失败。
[[email protected] rc.d]# vim /etc/my.cnf
[mysqld_safe]
log-error=/var/log/mariadb/mariadb.log ###错误日志路径
pid-file=/var/run/mariadb/mariadb.pid
###查看/var/log/下并没有mariadb目录，于是有三种方法解决：
1.mv /etc/my.cnf /etc/my.cnf.bak ###使/etc/my.cnf失效
2.vim /etc/my.cnf
#log-error=/var/log/mariadb/mariadb.log ###注销掉
3.mkdir /var/log/mariadb ###创建mariadb目录
[[email protected] mysql]# mkdir /var/log/mariadb ###此处使用第三种方法
[[email protected] mysql]# service mysqld start
Starting MySQL... SUCCESS! ###成功启动
###修改环境变量
[[email protected] rc.d]# vim /etc/profile.d/mysql.sh
export PATH=/usr/local/mysql/bin:$PATH
[[email protected] rc.d]# source /etc/profile.d/mysql.sh ###重读此配置文件
###导出头文件
[[email protected] rc.d]# ln -sv /usr/local/mysql/include/ /usr/include/mysqld
"/usr/include/mysqld" -> "/usr/local/mysql/include/"
###导出库文件
[[email protected] ld.so.conf.d]# vim /etc/ld.so.conf.d/mysql.conf
/usr/local/mysql/lib
[[email protected] ld.so.conf.d]# ldconfig ###系统重载入系统库
[[email protected] ld.so.conf.d]# ldconfig -p |grep mysql ###查看库文件读取
libmysqld.so.18 (libc6,x86-64) => /usr/local/mysql/lib/libmysqld.so.18
libmysqld.so (libc6,x86-64) => /usr/local/mysql/lib/libmysqld.so
libmysqlclient.so.18 (libc6,x86-64) => /usr/lib64/mysql/libmysqlclient.so.18
libmysqlclient.so.18 (libc6,x86-64) => /usr/local/mysql/lib/libmysqlclient.so.18
libmysqlclient.so (libc6,x86-64) => /usr/local/mysql/lib/libmysqlclient.so
###mysql安全加固
[[email protected] bin]# mysql_secure_installation ###运行此命令进行设置
