MySQL galera 安装过程遇到的问题及解决方案

1: 缺乏 libaio 包, libaio是linux下的一个异步非阻塞方式读写文件的接口。
[root@12 mysql]# ./scripts/mysql_install_db --user=mysql
Installing MySQL system tables...
./bin/mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directorynode

解决办法:安装之
mysql

Solution:yum -y install libaio-devellinux

2: 缺乏 openssl 包
sql

[root@12 mysql]# ./scripts/mysql_install_db --user=mysql
Installing MySQL system tables...
./bin/mysqld: error while loading shared libraries: libssl.so.6: cannot open shared object file: No such file or directoryapp

解决办法:先检查全部全部的 $PATH 目录是否包含libssl*连接库,若是有,能够作软连接改变名字,若是没有,安装之
异步

Solution:yum -y install openssl-devel
[root@12 mysql]# cd /usr/lib
[root@12 lib]# ls libssl.so
libssl.so
[root@12 lib]# ln -s libssl.so libssl.so.6
[root@12 lib]#ln -s libcrypto.so libcrypto.so.6测试

3:在安装过程当中,检查配置文件的错误ui

[root@12 mysql]# ./scripts/mysql_install_db --defaults-file=my_wresp.cnf --user=mysql
Installing MySQL system tables...
131213 17:13:28 [ERROR] WSREP: Query cache is not supported (size=67108864 type=1)
131213 17:13:28 [ERROR] Abortinglua

解决办法:测试过程当中就按照错误信息修改便可,至于缘由,过后再行计较。
code

Solution:
删除全部query cache相关的配置选项
[root@12 ]# cat /etc/my.cnf | grep queyr_cache
query_cache_size = 64M
query_cache_limit = 2M

4:与上面相同处理

131213 18:03:21 [ERROR] WSREP: Parallel applying (wsrep_slave_threads > 1) requires innodb_autoinc_lock_mode = 2.
131213 18:03:21 [ERROR] Aborting
add in my_wsrep.cnf:innodb_autoinc_lock_mode=2

5:缺乏相关的模块
131215 0:15:31 [Note] WSREP: Requesting state transfer: success, donor: 0
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors
WSREP_SST: [ERROR] Error while getting data from donor node: exit codes: 0 2 (20131215 00:15:34.320)
WSREP_SST: [ERROR] Cleanup after exit with status:32 (20131215 00:15:34.332)
WSREP_SST: [INFO] Removing the sst_in_progress file (20131215 00:15:34.349)
131215 0:15:34 [ERROR] WSREP: Process completed with error: wsrep_sst_xtrabackup --role 'joiner' --address '192.168.1.46' --auth '' --datadir '/usr/local/mysql/var/' --defaults-file '/etc/my.cnf' --parent '2714': 32 (Broken pipe)
131215 0:15:34 [ERROR] WSREP: Failed to read uuid:seqno from joiner script.
131215 0:15:34 [ERROR] WSREP: SST failed: 32 (Broken pipe)
131215 0:15:34 [ERROR] Aborting

Solution :
yum install perl-Time-HiRes
yum -y install perl-DBD-MySQL.x86_64
yum -y install libaio*

6. 端口被占用

WSREP_SST: [INFO] Evaluating socat -u TCP-LISTEN:4444,reuseaddr stdio | tar xfi - --recursive-unlink -h; RC=( ${PIPESTATUS[@]} ) (20140128 15:35:07.478)
2014/01/28 15:35:07 socat[10521.3077941584] E bind(11, {AF=2 0.0.0.0:4444}, 16): Address already in use
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

解决办法,找到占用端口的程序,杀掉(比较暴力,也能够换端口,可是初次安装为简单起见,暴力)

Solution: [root@12 ~]# lsof -i :4444 lsof: no pwd entry for UID 503 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME lsof: no pwd entry for UID 503 socat 5256 503 11u IPv4 13450 0t0 TCP *:krb524 (LISTEN) [root@12 ~]# kill -9 5256 [root@12 ~]# lsof -i :4444 [root@12 ~]# lsof -i :4444
