CentOS7 離線編譯安裝Mysql5.7
阿新 • • 發佈：2018-12-16
First
下載Mysql-5.7的rpm-bundle版本，並使用xftp或者flashftp等工具上傳到CentOS上
Second
tar xvf mysql-5.7.23-1.el7.x86_64.rpm-bundle.tar ，解壓後會有很多rpm包，如下所示
mysql-community-client-5.7.23-1.el7.x86_64.rpm mysql-community-common-5.7.23-1.el7.x86_64.rpm mysql-community-devel-5.7.23-1.el7.x86_64.rpm mysql-community-embedded-5.7.23-1.el7.x86_64.rpm mysql-community-embedded-compat-5.7.23-1.el7.x86_64.rpm mysql-community-embedded-devel-5.7.23-1.el7.x86_64.rpm mysql-community-libs-5.7.23-1.el7.x86_64.rpm mysql-community-libs-compat-5.7.23-1.el7.x86_64.rpm mysql-community-minimal-debuginfo-5.7.23-1.el7.x86_64.rpm mysql-community-server-5.7.23-1.el7.x86_64.rpm mysql-community-server-minimal-5.7.23-1.el7.x86_64.rpm mysql-community-test-5.7.23-1.el7.x86_64.rpm
Third
rpm -ivh mysql-community-server-5.7.23-1.el7.x86_64.rpm --nodeps ，忽略依賴關係分別安裝上面的包，其中server和server-minimal衝突，只安裝server即可。安裝成果反應如下：
[[email protected] mysql57]# rpm -ivh mysql-community-server-5.7.23-1.el7.x86_64.rpm --nodeps
warning: mysql-community-server-5.7.23-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing.. 安裝後可以通過，rpm -q 包名來檢視是否安裝上了，這裡有關rpm的命令推薦一篇文章《centos7 RPM包之rpm命令》
[tips]安裝過程中，可能會遇到conflict 報錯，比如下面：
[[email protected] mysql57]# rpm -ivh mysql-community-server-5.7.23-1.el7.x86_64.rpm --nodeps
warning: mysql-community-server-5.7.23-1.el7.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY
Preparing... ################################# [100%]
file /etc/my.cnf from install of mysql-community-server-5.7.23-1.el7.x86_64 conflicts with file from package mariadb-libs-1:5.5.52-1.el7.x86_64
這是提示你係統中原來的包和你現在安裝的包衝突了，那麼你需要先解除安裝掉原來的包yum -y remove mariadb-libs.x86_64，再來安裝現在的包
Four
初始化mysql，systemctl start mysqld，MySQL自動會在/var/log/mysqld.log中隨機生成一個[email protected]密碼，grep 'password' /var/log/mysqld.log，返回如下：
2018-10-18T05:30:58.336743Z 0 [Note] Shutting down plugin 'sha256_password'
2018-10-18T05:30:58.336749Z 0 [Note] Shutting down plugin 'mysql_native_password'
2018-10-18T05:31:28.958031Z 0 [Note] Shutting down plugin 'sha256_password'
2018-10-18T05:31:28.958043Z 0 [Note] Shutting down plugin 'mysql_native_password'
2018-10-18T05:41:37.082893Z 0 [Note] Shutting down plugin 'sha256_password'
2018-10-18T05:41:37.082900Z 0 [Note] Shutting down plugin 'mysql_native_password'
2018-10-18T05:48:59.273589Z 1 [Note] A temporary password is generated for [email protected]: gs<7CafauqzL
這裡我的隨機密碼為gs<7CafauqzL
[tips]這裡可能會出現沒有temporary password的情況，又可能是你的歷史殘留檔案導致MySQL以為已經初始化過了，所以rm -rf /var/lib/mysql，刪掉歷史檔案，重啟mysqld即可以初始化成功
Five
mysql -uroot -p ，使用隨機密碼登陸，首次登陸必須修改密碼，否則不能進行任何資料操作
mysql> show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
此處提示，必須先重置密碼
Six
alter user [email protected] identified by ‘your pwd’
需要注意的是，這裡密碼必須為含有大小寫字母、符號和數字的組合，才可以重置成功
