一、mysql安装包解压，注意下载的mysql包必须与操作系统版本需求一致。 [root@node1 soft]# ls mysql-5.7.11-1.el5.i686.rpm-bundle.tar [root@node1 soft]# ls -l total 600552 -rw-r--r-- 1 root root 614359040 Feb 18 12:02 mysql-5.7.11-1.el5.i686.rpm-bundle.tar [root@node1 soft]# tar -xvf mysql-5.7.11-1.el5.i686.rpm-bundle.tar mysql-community-libs-5.7.11-1.el5.i686.rpm mysql-community-common-5.7.11-1.el5.i686.rpm mysql-community-libs-compat-5.7.11-1.el5.i686.rpm mysql-community-server-5.7.11-1.el5.i686.rpm mysql-5.7.11-1.el5.i686.rpm mysql-community-test-5.7.11-1.el5.i686.rpm mysql-community-devel-5.7.11-1.el5.i686.rpm mysql-community-client-5.7.11-1.el5.i686.rpm mysql-community-embedded-5.7.11-1.el5.i686.rpm mysql-community-embedded-devel-5.7.11-1.el5.i686.rpm 二、安装mysql [root@node1 soft]# rpm -ivh mysql-community-server-5.7.11-1.el5.i686.rpm warning: mysql-community-server-5.7.11-1.el5.i686.rpm: Header V3 DSA signature: NOKEY, key ID
5072e1f5 error: Failed dependencies: mysql-community-client = 5.7.11-1.el5 is needed by mysql-community-server-5.7.11-1.el5.i686 mysql-community-common = 5.7.11-1.el5 is needed by mysql-community-server-5.7.11-
--mysql会自动添加mysql用户 [root@node1 soft]# id mysql uid=27(mysql) gid=27(mysql) groups=27(mysql) [root@node1 soft]# ls -l total 1201144 -rw-r--r-- 1 7155 wheel 40516 Feb 2 17:27 mysql-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 root root 614359040 Feb 18 12:02 mysql-5.7.11-1.el5.i686.rpm-bundle.tar -rw-r--r-- 1 7155 wheel 32644512 Feb 2 17:31 mysql-community-client-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 825859 Feb 2 17:31 mysql-community-common-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 5402990 Feb 2 17:31 mysql-community-devel-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 53512687 Feb 2 17:31 mysql-community-embedded-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 168617172 Feb 2 17:31 mysql-community-embedded-devel-5.7.11-
1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 2968131 Feb 2 17:32 mysql-community-libs-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 2172050 Feb 2 17:32 mysql-community-libs-compat-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 209431525 Feb 2 17:33 mysql-community-server-5.7.11-1.el5.i686.rpm -rw-r--r-- 1 7155 wheel 138730825 Feb 2 17:34 mysql-community-test-5.7.11-1.el5.i686.rpm
三、使用mysql安全登陆，修改root账号密码
[root@node1 ~]# mysqld_safe --skip--tables & [1] 5379 [root@node1 ~]# Usage: grep [OPTION]... PATTERN [FILE]... Try `grep --help' for more information. grep: write error: Broken pipe 2016-02-29T19:40:08.792329Z mysqld_safe Logging to '/var/log/mysqld.log'. 2016-02-29T19:40:08.861817Z mysqld_safe A mysqld process already exists
[root@node1 ~]# mysql -u root mysql Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A
mysql> select rurrent_user; ERROR 1054 (42S22): Unknown error 1054 mysql> mysql> use mysql Database changed mysql> mysql> mysql> update mysql.user set authentication_string=password('root') where user='root'; Query OK, 0 rows affected, 1 warning (0.00 sec)
