Mysqlbinlog can not parse row based events, mysqlbinlogparse

During the recent MHA test, the version of the mysqlbinlog client is lower than that of the server. The error message is mysqlbinlog is 3.2 (encoded in MySQL Client 5.0 or lower), but MySQL server version is 5.6.22-log. mysqlbinlog can not parse row based events. This should be a common error. This is mainly because mysql-related rpm packages are usually installed on your own during Linux installation, and later versions of mysql are installed on higher versions. The following describes the problem.

2. Fault Analysis
### View the current mysqlbinlog
# Which mysqlbinlog
/App/soft/mysql/bin/mysqlbinlog

### Mysqbinlog version, which is 3.4
# Mysqlbinlog -- version
Mysqlbinlog Ver 3.4 for Linux at x86_64

### Check whether mysqlbinlog exists in the default path. The following query does exist:
# Ls-hltr/usr/bin/mysqlbinlog
-Rwxr-xr-x 1 root 97 K 2013-01-23/usr/bin/mysqlbinlog

### View the default version number of mysqlbinlog, Which is 3.2, which is consistent with the fault description. The version is too low.
#/Usr/bin/mysqlbinlog -- version
/Usr/bin/mysqlbinlog Ver 3.2 for redhat-linux-gnu at x86_64

3. troubleshooting
### Directly use soft links to set the mysqlbinlog version called by MHA to version 3.4
# Mv/usr/bin/mysqlbinlog. bk
# Ln-s/app/soft/mysql/bin/mysqlbinlog/usr/bin/mysqlbinlog
#/Usr/bin/mysqlbinlog -- version
/Usr/bin/mysqlbinlog Ver 3.4 for Linux at x86_64

### You can also uninstall the current mysql rpm package of the system. If there is no mysql instance in the default path, follow these steps:
# Rpm-qa | grep mysql
Mysql-5.0.95-5.el5_9
# Rpm-e -- nodeps mysql-5.0.95-5.el5_9
Warning:/etc/my. cnf saved as/etc/my. cnf. rpmsave
# More/etc/my. cnf
/Etc/my. cnf: No such file or directory

### Note: After the default rpm package is uninstalled, the default my. cnf is copied to/etc/my. cnf. rpmsave and needs to be copied back.
# Cp/etc/my. cnf. rpmsave/etc/my. cnf
