MYSQL缺少libmysqlclient.so.16文件

Posted 2023-04-18

<table cellSpacing=0 cellPadding=0><tbody><tr><td>mysqldump: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory我是fedora8 前一天还好好的 第二天就不能mysqldump了，其他没问题，在远程也可以备份有libmysqlclient.so.15的文件 请高手支招 谢谢！</td></tr></tbody></table>

原因：没有加载成功造成的。

1、首先找到libmysqlclient.so.16文件的位置：

 [root@iZbp11rfoyeescusr9ha9qZ ~]# locate libmysqlclient.so.16

 /usr/lib64/mysql/libmysqlclient.so.16

/usr/lib64/mysql/libmysqlclient.so.16.0.0

2、然后在/etc/ld.so.conf中添加一行“/usr/lib64/mysql/libmysqlclient.so.16”，并重新加载配置：

 [root@iZbp11rfoyeescusr9ha9qZ ~]# echo "/usr/lib64/mysql/libmysqlclient.so.16" >> /etc/ld.so.conf

 [root@iZbp11rfoyeescusr9ha9qZ ~]# ldconfig

3、之后重启zabbix-server服务，即可成功启动服务：

 [root@iZbp11rfoyeescusr9ha9qZ ~]# 

 [root@iZbp11rfoyeescusr9ha9qZ ~]# /etc/init.d/zabbix-server start  Starting Zabbix server:                                    [  OK  ]

参考技术A

原因可能是安装mysql时，直接源码安装的，有些库没有导入。

1、从mysql官网下载包，如下图

2、解压压缩包

MySQL-client-5.6.36-1.linux_glibc2.5.x86_64.rpm    　    #MySQL客户端程序

MySQL-devel-5.6.36-1.linux_glibc2.5.x86_64.rpm           #MySQL的库和头文件

MySQL-embedded-5.6.36-1.linux_glibc2.5.x86_64.rpm        #MySQL的嵌入式程序

MySQL-server-5.6.36-1.linux_glibc2.5.x86_64.rpm          #MySQL服务端程序

MySQL-shared-5.6.36-1.linux_glibc2.5.x86_64.rpm          #MySQL的共享库

MySQL-shared-compat-5.6.36-1.linux_glibc2.5.x86_64.rpm   #RHEL兼容包

MySQL-test-5.6.36-1.linux_glibc2.5.x86_64.rpm            #MySQL的测试组件

3、取其中的MySQL-shared-compat-5.6.36-1.linux_glibc2.5.x86_64.rpm，执行安装

[root@iZ23tjtbt43Z opt]# rpm -ivh MySQL-shared-compat-5.6.36-1.linux_glibc2.5.x86_64.rpm 

warning: MySQL-shared-compat-5.6.36-1.linux_glibc2.5.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID 5072e1f5: NOKEY

4.、安装perl-DBD-MySQL，这样就完成了。

参考技术B 1 确保安装了同一版本的mysql-server, mysql-client, mysql-shared；
2 如果还提示找不到libmysqlclient.so.16 ，使用下面定位so位置并建立软链接；
>whereis libmysqlclient.so.16
>ldd /usr/bin/mysqldump --这个会使用那些so及路径，也包括了not found的libmysqlclient.so.16
>LD_DEBUG=libs /usr/bin/mysqldump -v
--根据上边结果建立软链接，前一个为映射的位置，后边为文件实际路径（根据实际情况创建）

>ln -s /usr/lib/mysql/libmysqlclient.so.16 /usr/lib64/mysql/libmysqlclient.so.16

收工。 参考技术C 1 确保安装了同一版本的mysql-server, mysql-client, mysql-shared；
2 如果还提示找不到libmysqlclient.so.16 ，使用下面定位so位置并建立软链接；
>whereis libmysqlclient.so.16
>ldd /usr/bin/mysqldump --这个会使用那些so及路径，也包括了not found的libmysqlclient.so.16
>LD_DEBUG=libs /usr/bin/mysqldump -v
--根据上边结果建立软链接，前一个为映射的位置，后边为文件实际路径（根据实际情况创建）

>ln -s /usr/lib/mysql/libmysqlclient.so.16 /usr/lib64/mysql/libmysqlclient.so.16 参考技术D mysql-shared-compat 找这个对应你mysql版本的rpm包安装。

【问题描述】：

首先要建议我是新手，而我的网页设计师不在国外。我有以下问题并寻求一些建议。我已经重新安装了 mysqldb 并升级了软件包。我和我的托管公司谈过，他们建议他们升级到 mysql 5.5。

我搜索了 web 和 ***，并尝试了上述许多不同的解决方案。

这是来自服务器错误日志的错误：

在写这篇文章时，我从我的托管公司那里发现了更多信息，我被告知以下内容

基本上我们将 libmysqlclient 更新为： libmysqlclient_r.so.18

来自： libmysqlclient_r.so.16

由于处于共享托管环境中，我们必须使这些 不时更新。看来这是导致您的原因 悲伤/问题。

您要么需要在本地重新安装 libmysqlclient_r.so.16 您的服务器没有 root 访问权限。 （没有百胜）

OR B 配置您的脚本以处理新的 .18 版本。

如果您采用第一种方式，则以后无需更新。如果 你用第二种方法，我们决定再次更新。它会 要求您再次更新脚本

对此很陌生，所以我不知道该怎么做，但愿意学习...请任何帮助表示赞赏。

【问题讨论】：

您能告诉我们您正在运行什么发行版，以及 django 是如何安装的吗？

我不确定 django 是如何安装的。我不是设计师。他正在休假。至于版本，你去吧！ Linux 版本 2.6.32-20120131.55.1.bh6.x86_64 ([e-mail]) (gcc 版本 4.4.6 20110731 (Red Hat 4.4.6-3) (GCC)) #1 SMP 1 月 31 日 15 日星期二： 2012 年美国东部标准时间 43:27

至于django你指的是easy_install吗？
