ERROR: [3] bootstrap checks failed

解决方法
[root@localhost ~]# vi /etc/security/limits.conf
在文件的末尾加上
esyonghu soft nofile 65536
esyonghu hard nofile 65536
esyonghu soft nproc 4096
esyonghu hard nproc 4096
进入到下面文件夹
[root@localhost ~]# cd /etc/security/limits.d
[root@localhost limits.d]# ll
total 4
-rw-r--r--. 1 root root 191 Nov 6 2016 20-nproc.conf
[root@localhost limits.d]# vi 20-nproc.conf
# Default limit for number of user's processes to prevent
# accidental fork bombs.
# See rhbz #432903 for reasoning.
* soft nproc 4096
root soft nproc unlimited
~
~
将上面内容的*号改成用户名
# See rhbz #432903 for reasoning.
esyonghu soft nproc 4096
root soft nproc unlimited
修改下面文件加上内容
[root@localhost security]# vi /etc/sysctl.conf
vm.max_map_count = 655360
对于上面的内容让其生效
[root@localhost security]# sysctl -p
vm.max_map_count = 655360
