安裝
我已經(jīng)把安裝包放到/usr/local/software路徑下面
[root@localhost software]# ls
mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar
查看是否已經(jīng)安裝mysql
rpm -qa | grep mysql
解壓tar文件
- 命令
tar -xvf mysql-5.7.19-1.el7.x86_64.rpm-bundle.tar

卸載沖突的RPM組件
在我們安裝mysql相關(guān)組件的時(shí)候，如果不將此沖突的組件刪除掉，我們是安裝不成功的。
我們可以先跳過這步，直接進(jìn)入下步操作，在安裝的過程中會(huì)有相應(yīng)的提示。下面是我所碰到的一個(gè)提示：
# 安裝mysql組件時(shí)出現(xiàn)的依賴錯(cuò)誤
error: Failed dependencies:
mysql-community-common(x86-64) >= 5.7.9 is needed by mysql-community-libs-5.7.19-1.el7.x86_64
mariadb-libs is obsoleted by mysql-community-libs-5.7.19-1.el7.x86_64
# 卸載mariadb-libs時(shí)出現(xiàn)的依賴錯(cuò)誤
error: Failed dependencies:
libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
可以看出，我們需要卸載postfix和mariadb-libs相關(guān)的組件。卸載我們可以使用rpm -ev xxx。
- 查看
postfix和mariadb-libs
rpm -qa | grep postfix
rpm -qa | grep mariadb

安裝依賴組件
在我進(jìn)行安裝msql-community-server-xxx的時(shí)候出現(xiàn)了下面的問題
[root@localhost software]# rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm
warning: mysql-community-server-5.7.19-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
error: Failed dependencies:

perl(strict) is needed by mysql-community-server-5.7.19-1.el7.x86_64
[root@localhost software]#
由上面的錯(cuò)誤可以看出我們需要安裝相應(yīng)的依賴
libaionet-toolsperl
- 安裝依賴
yum -y install libaio
yum -y install net-tools
yum -y install perl
安裝mysql組件
經(jīng)過上面的解壓操作，我們得到了很多rpm文件。但是我們不需要這么多，我們只需要安裝一下四個(gè)組件就可以了：
mysql-community-common-5.7.19-1.el7.x86_64.rpm
mysql-community-libs-5.7.19-1.el7.x86_64.rpm
mysql-community-client-5.7.19-1.el7.x86_64.rpm
mysql-community-server-5.7.19-1.el7.x86_64.rpm
因?yàn)榫哂?strong>依賴關(guān)系，所以我們需要按順序執(zhí)行。
用rpm -ivh 文件名就能安裝相應(yīng)的組件。
在執(zhí)行server的時(shí)候，需要依賴安裝一些工具組件，已經(jīng)在上文有說明了
- 安裝命令
rpm -ivh mysql-community-common-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-5.7.19-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-5.7.19-1.el7.x86_64.rpm
- 執(zhí)行過程

啟動(dòng)數(shù)據(jù)庫
# 查看mysql是否啟動(dòng)
service mysqld status
# 啟動(dòng)mysql
service mysqld start
# 停止mysql
service mysqld stop
# 重啟mysql
service mysqld restart
修改密碼
mysql安裝完成之后我們是沒有設(shè)置密碼的，但是mysql為我們設(shè)置了一個(gè)臨時(shí)的密碼，我們可以查看mysql的日志知道這個(gè)臨時(shí)密碼。
- 查看臨時(shí)密碼
grep password /var/log/mysqld.log
- 執(zhí)行過程
[root@localhost ~]# grep password /var/log/mysqld.log
2017-09-01T16:43:10.889769Z 1 [Note] A temporary password is generated for root@localhost: hcLMTxbOh2?w
這樣我們得知臨時(shí)密碼是：hcLMTxbOh2?w。
然后我們用這個(gè)臨時(shí)密碼登錄數(shù)據(jù)庫。
數(shù)據(jù)庫的密碼需要滿足以下條件：大小寫字母，數(shù)字和特殊符號(hào)
- 執(zhí)行命令
# 登錄mysql，之后需要輸入密碼
mysql -p
# 設(shè)置新密碼
set password = password("Mysql_123456");
# 退出當(dāng)前登錄
quit;
- 執(zhí)行過程
[root@localhost ~]# mysql -p
Enter password:

重新登錄，這樣我們就能用新的密碼登錄了。我們可以愉快的進(jìn)行數(shù)據(jù)庫操作了。
