Show the default password for the root user<\/h3>\n\n\n\n<p>When you install MySQL 8.0, the root user account is granted a temporary password. To show the password of the root user account, you use the following command:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-3\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">sudo grep <span class=\"hljs-string\">'temporary password'<\/span> \/<span class=\"hljs-keyword\">var<\/span>\/log\/mysqld.log | awk <span class=\"hljs-string\">'{print $NF}'<\/span>\r<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-3\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Here is the output:<\/p>\n\n\n<pre class=\"wp-block-code\"><span><code class=\"hljs\">Kq%&lt;ul_0M*O0<\/code><\/span><\/pre>\n\n\n<p>Note that your temporary password will be different.
