mysql - Mariadb 没有启动。控制进程退出

Question

我正在尝试使用 systemctl start mariadb 启动 mariadb，也尝试使用 sudo。

是这样写的

Job for mariadb.service failed because the control process exited with error code. See "systemctl status mariadb.service" and "journalctl -xe" for details.

我在很多地方都看到了这一点，但没有任何帮助。

它失败了，我删除了，重新安装，没有任何反应。

这是/var/log/messages 的一部分

Jun 17 18:04:13 controller systemd: Unit mariadb.service entered failed state. 
Jun 17 18:04:13 controller systemd: mariadb.service failed.

我是 CentOS 和 mariadb 的新手，所以我不知道如何进行。

mariadb.log 说

2016-06-17 19:24:39 140652810123392 [Note] Server socket created on IP: '::'.
2016-06-17 19:24:39 140652810123392 [ERROR] Can't start server: Bind on TCP/IP port. Got error: 98: Address already in use
2016-06-17 19:24:39 140652810123392 [ERROR] Do you already have another mysqld server running on port: 3306 ? 2016-06-17 19:24:39 140652810123392 [ERROR] Aborting

这是我的.cnf

#
# This group is read both both by the client and the server
# use it for options that affect everything
#
[client-server]

#
# This group is read by the server
#
[mysqld]
port=5555
bind-address = 10.23.77.68
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0

#
# include all files from the config directory
#
!includedir /etc/my.cnf.d

我尝试在 my.cnf 中添加一行

port=5555

没有帮助，mariadb.log 说的和我之前提到的一样。

Answer 1

我是这样解决的:

1. 安装后

2. 运行:> mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/

3. 然后:>mysql_secure_installation

4. 然后:systemctl start mariadb

有了这个这个，我就可以解决了。
