安裝路徑：/application/mysql-5.5.56
1.前期準(zhǔn)備
mysql依賴(lài)
| libaioyum install -y libaio |
創(chuàng)建用戶mysql，以該用戶的身份執(zhí)行mysql
| useradd -s /bin/false -M mysql |
下載mysql二進(jìn)制包并解壓
| cd /toolswget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gztar -zxf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz -C /application/ |
切換到/application目錄，將mysql文件夾名改短,給mysql目錄做一個(gè)軟鏈接
| cd /application/mv mysql-5.5.56-linux-glibc2.5-x86_64/ mysql-5.5.56ln -s mysql-5.5.56/ mysql |
遞歸設(shè)置mysql目錄的所屬組和所屬用戶
| chown -R mysql:mysql mysql-5.5.56/ |
2.mysql目錄內(nèi)操作
| cd mysql |
初始化數(shù)據(jù)庫(kù)
會(huì)在mysql目錄內(nèi)生成一個(gè)data目錄，存放數(shù)據(jù)庫(kù)的目錄
| ./scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data/ --user=mysql |
更改所屬用戶和組
| chown -R root .chown -R mysql data |
除了mysql目錄下的data目錄所屬用戶不變，其他所有文件的所屬用戶改為root
拷貝配置文件
| cp support-files/my-medium.cnf /etc/my.cnf |
將mysql的配置文件拷貝為/etc/目錄下的my.cnf
修改配置文件
| sed -i 28i'log-error=/application/mysql/data/mysqld.error' /etc/my.cnf |
在配置文件插入了一行，進(jìn)行配置錯(cuò)誤日志
