当前环境之前是装过MySQL官方版本5.6.22，想测试Percona版本MySQL。启动Percona-MySQL报错。
[[email protected] support-files]# /etc/init.d/mysql start
my_print_defaults: error while loading shared libraries: libssl.so.6: cannot open shared object file: No such file or directory
Starting MySQL (Percona Server)Couldn‘t find MySQL server ([FAILED]al/Percona-Server-5.6.21-rel70.1-698.Linux.x86_64/bin/mysqld_safe)
查看系统openssl是有装的，
[[email protected] ~]# rpm -ql openssl

[[email protected] lib64]# ll libssl
libssl3.so libssl.so libssl.so.0.9.8e libssl.so.10 libssl.so.1.0.1e
看来依赖的版本是低版本的，
[[email protected] lib64]# ll libssl.so.10
lrwxrwxrwx 1 root root 16 Dec 4 19:47 libssl.so.10 -> libssl.so.1.0.1e
[[email protected] lib64]#ln -sv libssl.so.1.0.1e libssl.so.6
再次启动，又报错，
[[email protected] /]# /etc/init.d/mysql start
my_print_defaults: error while loading shared libraries: libcrypto.so.6: cannot open shared object file: No such file or directory
Starting MySQL (Percona Server)Couldn‘t find MySQL server ([FAILED]al/Percona-Server-5.6.21-rel70.1-698.Linux.x86_64/bin/mysqld_safe)
只能想法解决版本问题了。
yum provides libcrypto.so.6 会出来是哪个rpm包 包含 这个lib库。
[[email protected] /]# yum provides libcrypto.so.6

顺便刚才那个也检查一下
[[email protected] /]# yum provides libssl.so.6

因为本环境是64位系统
[[email protected] /]# yum install openssl098e-0.9.8e-18.el6_5.2
[[email protected] /]# /etc/init.d/mysql start
Starting MySQL (Percona Server)... [ OK ]
能正常启动了
